concurring in part and dissenting in part:
I do not agree with the 10 percent royalty rate used by the majority. I also believe that the methodology used by the majority to arrive at that rate is not proper. Rather, it is my opinion that the graduated'rate recommended by the Government is the proper rate.
This court has held that where the patentee has by agreement established a royalty rate, that established rate is the measure of reasonable and entire compensation under 28 U.S.C. § 1498 (1970). In Calhoun v. United States, 197 Ct. Cl. 41, 55-56, 453 F. 2d 1385, 1393-1394 (1972), this court held as follows:
A. Claimants prefer to have compensation fixed by the Government’s cost-savings attributable to the invention; this has been found to be about $0.73 for each use. We agree, however, with the commissioner that while this court has, at times, looked to cost savings in determining compensation (Shearer v. United States, 101 Ct. Cl. 196, 60 USPQ 414, cert. denied, 323 U. S. 676 (1944); Olsson v. United States, 87 Ct. Cl. 642, 25 F. Supp. 495, 37 USPQ 767 (1938), cert. denied, 307 U. S. 621 (1939)), it has used a reasonable royalty as the basis in all cases where the evidence established a royalty rate used by the patentee in commercial licensing. * * * Here, the evidence shows that, starting in the 1940’s Christensen licensed the patent throughout the industry at a royalty of 0.25 cent for each O-ring used in an infringing structure. Furthermore, Christensen filed in the U. S. Patent Office in 1947, for announcement to the public, a form of license by which he offered to license the patent to anyone at a *282royalty of 0.25 cent per "packing construction.” Many licenses were so granted; and between 1946 and 1956, Christensen and his successors were paid royalties by commercial users at the rate of 0.25 cent per O-ring for 261,938,168 infringing structures. See Calhoun v. State Chem. Mfg. Co., 153 F. Supp. 293, 115 USPQ 120 (N.D. Ohio 1957). Thus, the patentee established a royalty which he deemed to be appropriate for use of the invention; and that royalty should form the basis for determining the compensation due plaintiffs.

See also Carley Life Float Co. v. United States, 74 Ct. Cl. 682 (1932); Saulnier v. United States, 161 Ct. Cl. 223, 314 F. 2d 950 (1963); Badowski v. United States, 150 Ct. Cl. 482, 278 F. 2d 934 (1960); Pitcairn v. United States, 212 Ct. Cl. 168, 547 F. 2d 1106 (1976). For convenience the above rule will be hereinafter referred to as the Calhoun rule. The rationale behind the rule is that where the patent owner voluntarily grants a license for consideration, it is only logical to conclude that he considers the consideration to be reasonable. It is a simple and just rule.
The Calhoun rule is also easy to apply. So in this case if it is shown that plaintiff, the patent owner, granted a license or licenses to others for consideration within the time frame relevant to this case, the royalty rate so established must be used to compute reasonable and entire compensation under 28 U.S.C. § 1498. Proof that plaintiff voluntarily granted three such licenses in this case is not only uncontradicted but admitted by plaintiff. Unfortunately, there has been a misinterpretation of the effect of the licenses because the label "royalty free cross license” is used to describe these licenses. I refer to portions of the majority opinion wherein these misinterpretations are apparent. The majority in the first sentence of Part II in its opinion states:
The parties are in agreement that plaintiff has no established licensing program or royalty applicable to the patents in this accounting. [Footnote omitted; emphasis supplied.]
The majority reiterates what the trial judge states in his opinion. However, I believe the majority’s amendment to the trial judge’s Findings of Fact 5 to be inconsistent with *283this statement. The majority’s change to Findings of Fact 5 is as follows:
2. In finding 5, insert the following after the first sentence: "However, the plaintiff granted to the Western Electric Company and RCA a royalty-free license in its patents in return for a license in certain groups of patents of those firms. Plaintiff also licensed the Hewlett-Packard Company, a major competitor, with a royalty-free cross-license in all patents of each firm.” [Emphasis supplied.]
By cross licenses plaintiff granted RCA, Western Electric and Hewlett-Packard the right to use plaintiffs patents in return for plaintiffs right to use their patents. The quid pro quo was the license each company exchanged. Therefore, if the licenses granted to plaintiff can be valued, their respective values, in turn, would establish the royalty value of plaintiffs license herein issue. This court must then, under the Calhoun rule, use the established rate to compute reasonable and entire compensation. In analyzing the cross license arrangement between plaintiff and RCA, Mr. Glassman, the expert Government witness, succinctly phrased it:
* * * under the royalty-free cross license, which included a royalty-free license to RCA under the Plaintiffs oscilloscope patents, RCA was giving up in return the opportunity to receive an effective royalty of 1.375 percent from the Plaintiff, and the Plaintiff was therefore in effect licensing RCA at an effective royalty rate of 1.375 percent of the Plaintiffs own sales. [Tr. 3876.]
In other words, in a royalty free cross license consideration passes between the parties. If the consideration is reduced to monetary terms, the established royalty of plaintiffs license to RCA, Western Electric or Hewlett-Packard may be effectively determined.
Plaintiff, by entering into cross license agreements with RCA, Western Electric and Hewlett-Packard, evaluated its own license; that value should now bind the plaintiff in the instant reasonable and entire compensation determination. Plaintiffs contracts with RCA, Western Electric and Hewlett-Packard should bind plaintiff as the .25 cent per O-ring license bound the patent owner in Calhoun and the *2842 percent United license bound the patent owner in Pitcairn, supra. In Pitcairn this court decided the effective royalty rate under aircraft patents there in issue mainly on the 2 percent United agreement voluntarily entered into by plaintiff-patent owner in that case. The court focused upon the United 2 percent agreement even though it was the only reliable agreement outstanding. This court held as follows:
It is a truism that patents can change or decline in value, and that seems to have been the case for Autogiro, even in its own eyes, during the post-war years. It wanted a package deal for any and all of its patents, and some of these were expiring from time to time. Engineering data for autogiros (manufactured in the pre-war era) were not useful for helicopters (the article made after the war). The post-war procurement of devices using plaintiffs inventions was bound to be very much larger than the pre-war purchases — and the royalty rates could therefore decline significantly. Nor is it a sign of invalidating compromise that, especially where a packet of patents is involved, there may have been some doubts as to the validity of some of the claims. Autogiro probably had some of those doubts itself and adjusted its demands accordingly. For these reasons the 2% United agreement seems to us highly probative under the rule we reiterated in Calhoun v. United States, 197 Ct. Cl. 41, 55-57, 453 F. 2d 1385, 1393-94 (1972). Calhoun teaches that the mere surmise that a bargained license may possibly include some discount for litigation-avoidance does not per se preclude use of an accepted commercial rate as establishing reasonable and entire compensation. Earlier, Saulnier v. United States, 161 Ct. Cl. 223, 314 F. 2d 950 (1963), took heavy account, in setting compensation, of the plaintiff’s previous settlement of infringement claims against the British government where that settlement appeared to be satisfactory and reasonable. See 161 Ct. Cl. at 226-27, 314 F. 2d at 951-52. [Footnote omitted; emphasis supplied.] [212 Ct. Cl. at 184-86, 547 F. 2d at 1117-18.]
In the instant case, there are three royalty agreements outstanding, but the majority elects to perfunctorily dismiss them as not relevant. They did not even refer to the Calhoun rule in summarily avoiding the three cross licenses. However, the Government’s expert witness, Mr. Glassman, used these three cross licenses and testified that *285in Ms opinion the royalty rate in this case should be as follows:
1.5 percent on the first $2 million,
1.2 percent on the next $3 million, and
1 percent on the remainder.
The majority rejected Mr. Glassman’s rates. It appears that the majority in taking that position did not seriously consider the three cross licenses by plaintiff with RCA, Western Electric and Hewlett-Packard, apparently because these licenses were labeled royalty free cross licenses. The following reasoning given by the majority at p. 266 bears this out:
The Government’s proposal is rejected because the evidence on which it is premised is not at all analogous to the facts here. Defendant relies on the licensing programs of RCA and Western Electric but it seems clear that plaintiff — which was not a company comparable in size to those corporate giants, nor possessed of either a comparable patent portfolio or a comparable product line, nor under the spur of an anti-trust decree — should not be governed by the same considerations. Items such as transistors, tubes, and similar electronic components are comparatively simple in structure, have a relatively low per-unit cost, and are sold and used in very large quantities. Plaintiffs oscilloscopes, on the other hand, are much more complex, have a much higher per-unit cost, and the quantities sold are much lower. [Footnote omitted; emphasis supplied.]
The majority intimates that the percentages presented by the Government have no relevance to plaintiffs oscilloscope patents. But as shown below, the three cross licenses were tied into plaintiffs oscilloscope patents by the testimony of defendant’s expert witness. Furthermore, the majority’s reference to the irrelevancy of transistor tubes in this litigation shows that the majority did not consider the portion of the record in this case in which the defendant’s expert witness analyzed the transistor license values; transistor values were tied into plaintiffs license of its oscilloscope patents by the cross licenses. Nevertheless, corporate sizes, patent portfolio sizes, anti-trust decrees, simplicities of transistors, volumes of sales and complexities of oscilloscopes are all of no relevance under the *286Calhoun rule where it is shown that plaintiff by its three cross license agreements established a royalty for its patents.
Mr. Glassman showed that from 1953 up to September 1, 1957, plaintiff was a licensee under RCA’s licenses which covered measuring and testing devices (Tr. 3812). Licenses for measuring and testing devices included patents on oscillographs. Plaintiff actually paid RCA royalties for these RCA licenses from 1953 to 1957; this was shown by royalty reports made by plaintiff to RCA. (Defendant’s Ex. DA-31E, F and G.) The royalty plaintiff paid RCA in said years was based on 1.5 percent for commercial units but 1 percent for Government sales (see Ex. DA-31D). On September 1, 1957, plaintiff and RCA entered into a cross licensing agreement (Ex. DA-31D) (Tr. 3874). Mr. Glass-man considered the prior payments to RCA by plaintiff to establish the reasonable royalty value of plaintiffs patents under the cross license.
As for the plaintiff-Western Electric cross license, Mr. Glassman showed that Western Electric owned patents on transistors which plaintiff used in the manufacture of its oscillographs. Plaintiff. found the use of these patents necessary. Western’s patents on the transistors were licensed to plaintiff by Western Electric. The rates on these one-way Western Electric to plaintiff transistor licenses were high; so plaintiff negotiated a lower, 1.5 percent, rate in exchange for royalty free use of plaintiffs patents by Western. This was the Western Electric-plaintiff cross license (Tr. 262, 264, 270). Defendant’s witness also used the value of royalties on the transistor patents owned by Western Electric to establish the values of royalties on plaintiffs patents in issue in this case.
No one questioned Mr. Glassman’s expertise in the field of royalty rates on patents, especially in the electronics field. His testimony covered 219 pages (Tr. 3773 to 3992). In Pitcairn, supra, his qualifications are fully listed at 219-20. I do not think it necessary to repeat his qualifications. In the instant case, Mr. Glassman testified that in establish*287ing his graduated royalty rate, starting with 1.5 percent, he considered eight elements which I list in the margin.1
I feel that the majority, when they rejected the above-quoted rates suggested by the Government, were overly influenced by plaintiffs profits. They stated at 266:
* * * Moreover, the evidence is that during the -1960’s, plaintiff was realizing on its commercial sales an average profit of 23.7% on the 535 scope and 27.7% on the 545 scope, those figures reflecting plaintiffs margin on these products after both direct and indirect costs had been considered. In view of those figures, defendant’s suggestion that plaintiff should be forced to accept a declining royalty starting at 1%% for its inventions could not, without the greatest difficulty, be accepted as just compensation for use of the patents.
The majority’s view above expressed conflicts with Mitchell v. United States, 267 U. S. 341 (1925), the leading case in the federal law of eminent domain on the subject whether business profits may be used as evidence in an eminent domain proceeding to determine reasonable compensation. In Mitchell v. United States, supra, at 345, the Court held:
* * * The settled rules of law, however, precluded his considering in that determination consequential damages for losses to their business, or for its destruction. Joslin Manufacturing Co. v. Providence, 262 U. S. 668, 675. Compare Sharp v. United States, 191 U. S. 341; Campbell v. United States, 266 U. S. 368. No recovery therefor can be had now as for a taking of the business. There is no finding as a fact that the Government took *288the business, or that what it did was intended as a taking. If the business was destroyed, the destruction was an unintended incident of the taking of land. There can be no recovery under the Tucker Act if the intention to take is lacking, Tempel v. United States, 248 U. S. 121. Moreover, the Act did not confer authority to take a business. In the absence of authority, even an intentional taking cannot support an action for compensation under the Tucker Act. United States v. North American Co., 253 U. S. 330.
Mitchell has been followed for 52 years2 as the federal law of eminent domain: excluding business profits of the condemnee owner to prove reasonable value of the condemned property. The majority argues that Almota Farmers Elevator & Warehouse Co. v. United States, 409 U. S. 470 (1973), stands for the broad proposition that "basic equitable principles of fairness are the governing consideration in determining just compensation for an eminent domain taking” but I do not think that it permits departure from the Mitchell rule. In Almota in footnotes 2 and 3, at pages 475-476, the majority Justices of the Court remind the dissenting Justices that Almota "is not a case where the petitioner is seeking compensation for lost opportunities.” The majority of the Court in Almota does not overrule Mitchell; rather, it assures the dissenting Justices in footnote 2 that Mitchell is still the federal law of eminent domain. Applying the Mitchell rule to the present case, defendant did not take plaintiffs business. Defendant took only a nonexclusive license under plaintiffs patents in issue in this case. It was highly improper for the majority to refer to plaintiffs percentage of profit.
In 4 Nichols, Eminent Domain (3d ed. rev. 1976), § 12.3121, relating to Profits as criteria of value, it is stated:
Past profits.
If the owner of property uses it himself for commercial purposes, the amount of profits from the business conducted upon the property depends so much upon the capital employed and the fortune, skill and good manage*289ment with which the business is conducted, that it furnishes no test of the value of the property. It is, accordingly, well settled that evidence of the profits of a business conducted upon land taken for the public use is not admissible in proceedings for the determination of the compensation which the owner of the land shall receive. * * * [Footnote omitted.]
Future profits.
The admission of evidence as to anticipated future profits is objectionable, not only upon the grounds stated with respect to past profits, but also on the further ground that such profits are necessarily conjectural. Future profits depend on so many contingencies that an accurate valuation cannot be based thereon. Experience and observation both show that paper future profits are more often illusory than real. [Footnote omitted.]
* * * * *
Capitalization of hypothetical income.
The capitalization of hypothetical income method of valuation has generally been rejected by the courts. In Matter of City of New York (Blackwell’s Island Bridge), a leading decision in this area, the court said:
"In regard to the vacant lots, parcel No. 31, a witness was asked what would be the best use to which these lots could be put; he replied: The erection of 'three apartment houses, * * * making each building about 33 feet’. He was then allowed to testify, over objections and exceptions, that the cost of constructing three such buildings would be $75,000, and that the rental value of such buildings would be between $14,000 and $15,000 a year. This was clear error. It involved so much of. the elements of uncertainty and speculation as to be inadmissible as proof of any fact. * * *” [Footnote omitted.]
In view of the Calhoun rule, it may not be necessary to discuss plaintiffs hypothetical profit computation using Hickok as the hypothetical licensee. Nevertheless, I make the following interesting observations. The hypothetical method used by the majority was adopted from the approach in Georgia-Pacific Corp. v. United States Plywood Corp., 318 F. Supp. 1116 (S.D. N.Y. 1970), aff’d, 446 F. 2d 295 (2d Cir.), cert. denied, 404 U. S. 870 (1971). The district court clearly stated that the hypothetical method may be employed only where there is no established royalty, citing *290a Supreme Court case for support. The district court held at 1121:
The parties agree that there was no "established” royalty for USP’s Weldtex or GP striated. Consequently, it is necessary to resort to a broad spectrum of other evidentiary facts probative of a "reasonable” royalty.
Two of the earlier and typical cases relied upon by both parties are Dowagiac Mfg. Co. v. Minnesota Moline Plow Co., 235 U. S. 641, 35 S. Ct. 221, 59 L. Ed. 398 (1915) and United States Frumentum Co. v. Lauhoff, 216 F. 610 (6th Cir. 1914). In Dowagiac Mfg. Co. supra, 235 U. S. at 648, 35 S. Ct. at 224, the Supreme Court said that, where a patentee could not prove lost profits, infringer’s profits or an established royalty, the patentee could "show the value by proving what would have been a reasonable royalty, considering the nature of the invention, its utility and advantages, and the extent of the use involved.” * * * [Emphasis supplied.]
In Dowagiac Manufacturing Co. v. Minnesota Moline Plow Co. 235 U. S. 641, 648 (1915), the Court stated:
* * * So, had the plaintiff pursued a course of granting licenses to others to deal in articles embodying the invention, the established royalty could have been proved as indicative of the value of what was taken, and therefore as affording a basis for measuring the damages. Philip v. Nock, 17 Wall. 460, 462; Birdsall v. Coolidge, 93 U. S. 64, 70; Clark v. Wooster, 119 U. S. 322, 326; Tilghman v. Proctor, 125 U. S. 136, 143. But, as the patent had been kept a close monopoly, there was no established royalty. In that situation it was permissible to show the value by proving what would have been a reasonable royalty, considering the nature of the invention, its utility and advantages, and the extent of the use involved. * * *
Therefore, even Georgia-Pacific does not permit using the hypothetical Hickok profit analysis approach where there is an established royalty shown, as in this case, by plaintiffs three cross licenses. I am also of the opinion that the hypothetical Hickok profit approach used by the majority cannot be used because it is a departure from the federal law of eminent domain. Hickok was an infringer but unlike defendant it was a non-Governmental infringer subject to damages only under 35 U.S.C. § 284 (1970). The history of the use of an infringer’s profits to determine a *291patent owner’s damages under 35 U.S.C. § 284 has been a stormy one.3 There still remains the question as to what Congress intended when it eliminated infringer’s profits in 1946 from section 284. It was thought that Aro Manufacturing Co. v. Convertible Top Replacement Co., 365 U. S. 336 (1961), resolved the ambiguity but Georgia-Pacific was one of the first cases to hold that Aro did not eliminate use of infringer’s profits to compute reasonable royalty by means of a "willing buyer-willing seller” hypothetical negotiation. See a discussion of this 1946 change in 3 White, Patent Litigation: Procedure & Tactics (1976), § 9.01[2]. White, at page 9-34, warns that use of the infringer’s profits under the Georgia-Pacific approach has resulted in "unusually high” awards in comparison to older cases. He also warns, at pages 9-24 to 9-25, that this infringer’s profit approach may again raise questions of allocation or apportionment of infringer’s profits under Dowagiac Manufacturing Co. v. Minnesota Moline Plow Co., supra, and Westinghouse Elec. and Mfg. Co. v. Wagner Elec. and Mfg. Co., 225 U. S. 604 (1912), and the "entire market” doctrine. White definitely tags the hypothetical approach in Georgia-Pacific as an anticipated profit approach. At page 9-33 he states:
Although the concept of the infringer’s profits does become involved in determining a reasonable royalty, it should be observed that the point of interest is not the profit which actually was realized but that which was anticipated. The Georgia-Pacific case illustrates the point, for G-P apparently contended that the market for the products involved in the suit, and presumably their profitability, decreased during the period of infringe*292ment. The court, however, emphasized the situation at the time the reasonable royalty would have been negotiated, and relied on the anticipated profits rather than those actually realized. [Footnotes omitted.]
I submit that since in Georgia-Pacific damages were assessed under 35 U.S.C. §'284, the limitations in establishing market value under the federal law of eminent domain were not considered. As shown above, the Mitchell rule which prescribes the use of profits as a measure of damages also limits use by this court of the hypothetical Hickok profit approach. The majority’s sole statutory authority for allowing plaintiff compensation is 28 U.S.C. § 1498, under the federal law of eminent domain. Therefore, Mitchell applies and prevents such a hypothetical profit approach.4
In addition, the following "apportionment rule” prevents the use of the Hickok hypothetical profit approach. In Westinghouse Elec. and Mfg. Co. v. Wagner Elec. and Mfg. Co., supra, involving an electrical converter to promote the efficiency of transformers, the Court stated at 614-615:
(d) But there are many cases in which the plaintiffs patent is only a part of the machine and creates only a part of the profits. His invention may have been used in combination with valuable improvements made, or other patents appropriated by the infringer, and each may have jointly, but unequally, contributed to the profits. In such case, if plaintiffs patent only created a part of the profits, he is only entitled to recover that part of the net gains. He must, therefore, "give evidence tending to *293separate or apportion the defendant’s profits and the patentee’s damages between the patented feature and the unpatented features, and such evidence must be reliable and tangible, and not conjectural or speculative; or he must show, by equally reliable and satisfactory evidence, that the profits and damages are to be calculated on the whole machine, for the reason that the entire value of the whole machine, as a marketable article, is properly and legally attributable to the patented feature.” Garretson v. Clark, 111 U. S. 120.
The Government’s expert witnesses described plaintiffs patent as .only an improvement patent (Tr. 3863) and plaintiffs own witnesses deposed that plaintiffs patents were improvement patents. Oscillographs were in use prior to and during World War II, before plaintiffs patents were ever in the picture. In fact, Jetronic Industries, Inc. was already in the business of manufacturing oscillographs before plaintiffs improvement patents were obtained. The war itself generated a tremendous amount of basic research in electronic circuitry, much of it financed under wartime Government contracts. Much of this basic work, performed at Radiation Laboratory at the Massachusetts Institute of Technology, related to the wartime need for improved radar and fire control systems. This pioneering work generated a large postwar spinoff in the form of a growing civilian electronics industry. Some of this basic work at the Massachusetts Institute of Technology Radiation Laboratory produced two basic oscilloscope patents to Chance and Washburn owned by the Government, which have previously been the subject of controversy in this case. Tektronix, Inc. v. United States, 173 Ct. Cl. 281, 351 F. 2d 630 (1965) [DA3-44, DA3-47, DA3-21A, DA3-21B], These patents are fundamental to the accused oscilloscopes and are cited as prior art references in many of the patents in suit [DA3-34, DA3-35, DA3-45, DA3-46, DA3-48, DA3-49, see deposition of Gunnar P. Ohman, DA3]. In this environment of radically changing technology during a period of tremendous growth for the entire electronics field, the plaintiff corporation was founded by Howard Vollum in 1946 specifically to design and ultimately to manufacture improved oscilloscopes. Tektronix, Inc. v. United States, 188 USPQ 25, 27 (Ct. Cl. Tr. Div., 1975); *294Finding 3. It is undisputed that during the period from 1946 to 1954, the plaintiff developed several improved circuits which, taken together, produced a technically advanced oscilloscope. Id. However, it is also clear that much of this improved circuitry was based on the Government’s wartime research work which had been generally made available to the public at large [DA3-46, DA3-49, see generally DA3].
In the second Georgia-Pacific district court decision, reported in 318 F. Supp. 1116, the court held at 1132:
This case does not permit application of the principle of apportionment inasmuch as the Deskey patent was not one for an improvement on an article nor was GP’s infringement of a patented feature sold together with unpatented parts. Decisions illustrating the rule applicable to patented improvements or to patented parts of articles also embodying unpatented parts are not apposite for the reason that the Deskey patent covered and Weldtex represented a marketable article — a panel of striated fir plywood — as an entirety. *****
In terms of a structural test, for example, the contribution of the Deskey invention cannot be isolated as a separate physical part. The invention permeated the plywood panel to such a degree that it should be considered as covering the article as a whole. In this situation, the invention was not only for an improvement.
The article involved in Georgia-Pacific was plywood so it could be said that the invention "permeated” the plywood panel, but the present case is like the transformer improvement patent in Westinghouse Elec. and Mfg. Co. v. Wagner Elec. and Mfg. Co., supra, where the Court recognized that electrical equipment is fundamentally made of many parts. The majority revived the much-feared problem of allocation of infringer’s profit, which Congress attempted to eliminate (see supra, footnote 3). The Chance patent and the Washburn patent owned by the Government were recited as prior art in the patents involved in the present case, and the said Government-owned patents were fundamental to the accused oscilloscopes. The mere fact that in Tektronix, Inc. v. United States, 173 Ct. Cl. 281, *295this court held that these two Government patents were not subject to counterclaim damages by the Government does not mean that under the Westinghouse Elec. and Mfg. Co. apportionment rule, this court need not apportion values attributable to the Chance and Washburn patents in computing eminent domain compensation under 28 U.S.C. § 1498. I believe that United States v. Fuller, 409 U. S. 488 (1973), is a leading eminent domain case for the proposition that the Government in a condemnation case may not be required to compensate a condemnee for elements of value that the Government has created. In Fuller the alleged added value was by 31,461 acres of Government-owned grazing lands adjacent to the condemnee’s ranch property of 1,280 acres owned in fee simple by the condemnee. In Fuller, at pages 492-493, the Court said:
These cases go far toward establishing the general principle that the Government as condemnor may not'be required to compensate a condemnee for elements of value that the Government has created, or that it might have destroyed under the exercise of governmental authority other than the power of eminent domain. If, as in Rands [389 U. S. 121 (1967)], the Government need not pay for value that it could have acquired by exercise of a servitude arising under the commerce power, it would seem a fortiori that it need not compensate for value that it could remove by revocation of a permit for the use of lands that it owned outright.
*****
We hold that the Fifth Amendment does not require the Government to pay for that element of value based on the use of respondents’ fee lands in combination with the Government’s permit lands.
I submit that the Chance and Washburn patents added value to plaintiffs patent, as were the Government-owned grazing lands added value to Fuller’s land. The grazing charges for those grazing lands were very minimal, virtually free.
With relation to the "entire market value rule” which the majority has suggested and used to avoid the apportionment of infringer’s profits under the Westinghouse rule, I answer by quoting from Marconi Wireless Telegraph Co. v.
*296United States, 99 Ct. Cl. 1, 46-47 (1942), modified on other grounds, 320 U. S. 1 (1943), where it is stated:
The status of a patent in the art with which it is associated is of importance in determining the base which is to be used in an accounting. The reason for this is succinctly set forth in Garretson v. Clark, 111 U. S. 120, in which it is stated:
When a patent is for an improvement, and not for an entirely new machine or contrivance, the patentee must show in what particulars his improvement has added to the usefulness of the machine or contrivance. He must separate its results distinctly from those of the other parts, so that the benefits derived from it may be distinctly seen and appreciated. The rule on this head is aptly stated by Mr. Justice Blatchford in the court below: "The patentee,” he says, "must in every case give evidence tending to separate or apportion the defendant’s profits and the patentee’s damages between the patented feature and the un-patented features, and such evidence must be reliable and tangible, and not conjectural or speculative; or he must show, by equally reliable and satisfactory evidence, that the profits and damages are to be calculated on the whole machine, for the reason that the entire value of the whole machine, as a marketable article, is properly and legally attributable to the patented feature.” [Italics ours.] '
From a consideration of subsequent cases, the application of this rule relates more directly to an accounting based upon profits rather than the type of accounting which is based on reasonable royalty and which has been followed in the present case with reference to the Lodge patent. This becomes apparent if we consider a theoretical instance, in which the profits, due to the patented portion of a machine, have on apportionment been found to be 25 percent of the total profits on the machine, the remaining 75 percent being due to extraneous elements or elements patented by others. In such a case plaintiff would be entitled only to the profits on the features or elements covered by his patent. If, however, the recovery of compensation in the same instance were measured by a reasonable royalty, such a procedure would take into consideration both the nature of the patented invention and its relation to the entire machine as a whole. Thus, in applying a reasonable royalty rule to the same situation just outlined, the differential between the patented and unpatented features of the machine would *297be taken into account by scaling down the percentage of royalty accordingly. It would make no difference in the ultimate compensation to plaintiff if the reasonable royalty were fixed at 5 percent of the selling price of the complete machine rather than 20 percent of one quarter of the sales price of the machine. [Emphasis supplied.]
In the present case, in its attempt to establish a royalty rate of a "willing-buyer/willing-seller,” the majority uses and depends on an accounting which is based upon profits of Hickok. Under jthe above-quoted passage from Marconi, before the majority can construct a hypothetical profit figure for Hickok, the majority must apportion the hypothetical profits between profits generated solely by plaintiffs oscillograph patents and profits attributable to "extraneous elements or elements patented by others.” In determining the "willing-buyer/willing-seller” royalty rate, the majority may use only the portion of Hickok’s profits allocable to plaintiffs patent; the majority may not include profits allocable to "extraneous elements or elements patented by others.” The "entire market value rule” may not be used to establish a rate which is based on unapportioned profits. Therefore, by using the unappor-tioned profits of Hickok without first segregating that portion of Hickok’s profits allocable to plaintiffs patents from that portion allocable to "extraneous elements or elements patented by others,” the majority repudiated the Marconi rule. Under the Marconi analysis, the majority should have allocated the gross profit figure of $118 between the portion attributable to plaintiffs patents and the other portions attributable to "extraneous elements or elements patented by others.” The record shows that patents "by others” in this case include patents by Chance (oscillographs), Washburn (oscillographs), Western Electric (transistors, photo transistors and diodes), RCA (oscillo-graphs) and Hewlett-Packard (oscillographs). In this respect, plaintiffs vice president, Mr. Weber, testified that the Western Electric, Hewlett-Packard and RCA patents were material considerations in plaintiffs cross license agreements. Mr. Glassman testified that an application of the lost profit theory in this case would be inappropriate because
*298* * * there was considerable uncertainty about what the Plaintiffs profits would have been even if they had been capable of accepting these contracts, and I have already referred to the impracticality of trying to determine the exact costs of those parts of the oscilloscope which used the patents in suit. So all these things put together, it seems to me, indicate that the lost profits theory is quite inappropriate. [Emphasis supplied.] [Tr. 3884.]
Therefore, I submit that in order to be consistent with the Calhoun rule and Saulnier, supra, Badowski, supra, and Pitcairn, supra, where a royalty rate is established by plaintiffs own cross licenses, that royalty rate established is the measure of reasonable and entire compensation. The total recovery computed using such established rate should not be summarily upset or changed by comparing the final figure to plaintiffs total profits or rate of profit from plaintiffs business, as the majority did. Plaintiffs business profits should not be an element in establishing plaintiffs recovery because defendant did not take plaintiffs business. We must not depart from Mitchell v. United States, supra. Under the Calhoun rule, in view of the existence of an Established royalty determined by reference to the three cross licenses between plaintiff and RCA, Western Electric and Hewlett-Packard, the Government’s suggested graduated rate, 1.5 percent on the first $2 million, 1.2 percent on the next $3 million and 1 percent on the remainder, should have been accepted by the majority.
I submit that use of the Hickok hypothetical profit approach by the majority was in error. Even Georgia-Pacific discusses the necessity of considering apportionment of infringer’s profits (Hickok) where the patent in issue is only an improvement patent; the majority, however, did not take up this problem of apportioning Hickok’s gross profit figure of $118. Defendant’s witness testified that if the Hickok profit were apportioned, the resulting rate would be much less than the 7.65 percent rate selected by the majority (Tr. 3908).
I submit that a willing buyer-willing seller approach using a hypothetical infringer’s profits as a basis of analysis is not only novel but without precedent in a suit under 28 U.S.C. § 1498 governed by the federal law of *299eminent domain. I submit that the majority erred in using the infringer’s profit approach for the reasons above stated.
Under the Government’s graduated rate, plaintiff is entitled to recover $185,445. ((Tr. 3845), Ex. DA-25, -26 - 27A.) As for the method of compensating delayed compensation, I agree with the majority.
FINDINGS OF FACT
The court, having considered the evidence, the findings of former Trial Judge Hal D. Cooper, and the briefs and arguments of counsel, makes findings of fact as follows:
1. The oscilloscopes (hereafter scopes) for which plaintiff seeks compensation are the following models: 1805, 1805A, USM/81, LA261, LA265, LA265A, LA545, AN/USM-105, AN/USM-140 series, and AN/USM-141 series.
2. All of the scopes here in issue are covered by one or more claims of one or more of the patents in suit. The patents in issue cover only portions of the accused scopes. None of the patents cover the preamplifier units, referred to as plug-ins, used with the scopes and scopes can be purchased without plug-ins; however, the scope has no utility without a plug-in and the practice most often followed is to order plug-ins from the same source as the scopes. The plug-ins are financially dependent on the market created by the patented scopes. Patent No. 2,883,619 is directed to an electrical probe. Plaintiffs evidence is insufficient to make any determination with respect to the probes.
3. Plaintiffs 535 and 545 scopes which embody the circuitry disclosed and claimed in the patents here in suit were the culmination of 7 years of research and development and were first offered for sale in 1954. Up to the time of the liability trial in 1965, plaintiff had sold more than 26,000 type-535 and more than 40,000 type-545 scopes producing revenues in excess of $100 million. The inventions of the patents in suit made a substantial contribution to oscilloscope technology, increasing the reliability and precision of measurements made with scopes and making it possible to do jobs which were practically impossible otherwise. Despite attempts by others to produce high-performance oscilloscopes with Government funding, plaintiffs scopes employing the patented circuitry in suit were the most technically advanced scopes available in 1958 and for several years thereafter. Oscilloscopes which did not have the patented circuitry were technically obsolete after *300introduction of the patented scopes. The wide range of sweep speeds and the plug-in versatility of plaintiffs scope made it possible to replace two or more older scopes or other instruments with one patented scope. No one else was able, in the late 1950’s and early 1960’s to manufacture a competitive scope of the same high performance and technical sophistication as plaintiffs scopes without using the patented circuitry.
4. (a) Defendant was not interested in procuring a scope which the third-party defendants designed and built. Defendant’s procurement procedure made it clear that it would accept only plaintiffs scope or a virtual copy thereof manufactured by one of the third-party defendants. In its early requests and invitations, defendant described the product it was seeking in language such as "Tektronix, Inc. Model 535 as manufactured by Hickok,” "Jetronic Model to meet characteristics of Tektronix Model 535,” "Tektronix Model 535 or equal,” or "Tektronix Model 545 or equal.” Later, when the third-party defendants had their own nomenclature describing their copy of plaintiffs scopes, defendant’s requests were phrased in the alternative such as "Tektronix 545A or Hickok 1805A or Lavoie LA265A.”
(b) In order to meet defendant’s requirements, Jetronics found it necessary to copy the physical layout and circuit design of the Tektronix 535 and used the Tektronix 535 performance specifications in manufacturing the USM/81. To comply with defendant’s requirements, Hickok copied the physical layout and circuit design of the Tektronix 535 in manufacturing its USM/81. Likewise, to meet defendant’s requirements, Hickok manufactured its 1805 as a copy of the Tektronix 545. Oh at least one occasion, in competing against plaintiff for a contract involving a Tektronix 545A-type oscilloscope, Hickok actually submitted to defendant a Tektronix-manufactured oscilloscope with a Hickok face plate and represented the scope as a bid sample of the scope that Hickok intended to manufacture. The three Lavoie scopes LA545, LA265, and LA265A are essentially the same instrument. No distinction was made by the court during the liability trial and the LA265 was considered representative of all. A comparison of the LA265 scope with the Tektronix 545A scope shows that the scopes are virtually identical in appearance and internal structure. A comparison of the LA261 scope and the LA261 manual with plaintiffs 516 scope and plaintiffs manual shows that the Lavoie LA261 is a copy of the Tektronix 516 in structure, appearance, specifications, and that in all material respects the two are identical. In addition to copying the mainframes of the scopes, both *301Hickok and Lavoie copied plaintiffs plug-in components which are inserted into the mainframe of the scope as part of the integral structure of the scope. Lavoie even used the same nomenclature as plaintiff to designate its plug-ins.
(c) Because the copies of plaintiffs instruments so closely resembled genuine Tektronix instruments, many of defendant’s employees thought the copies were made by plaintiff. When problems arose with the copies, plaintiffs field engineers were often called to fix the instruments. When they were called upon by defendant’s employees and asked for assistance, plaintiffs field engineers usually assisted defendant and provided information, service, and even repaired some of the copies of plaintiffs instruments. Often it was only after having made a special trip to a Government installation that plaintiffs field engineer realized he had been asked for assistance relating to a non-Tektronix instrument. Some employees of defendant asked plaintiffs field engineers for assistance relating to the copies even after realizing that the instruments were not made by plaintiff when they were unable to get help from the third-party defendants. Plaintiffs field engineers and instructors conducted training classes on plaintiffs instruments, many of which were attended by military personnel who then used the copies of plaintiffs instruments manufactured by Hickok or Lavoie. On some occasions, plaintiffs field engineers, at defendant’s request, drove great distances to remote military installations to teach military personnel how to use plaintiffs instruments, only to find that mainly copies were being used.
(d) Plaintiffs commercial scopes could have satisfied defendant’s needs for the USM/81, 1805, 1805A, LA545, LA265, LA265A, and LA261 types of scopes. The AN/USM-105 and the AN/USM-140 and 141 series were militarized versions which plaintiff did not make and on which plaintiff did not seek to bid.
5. Although plaintiff has a policy of actively seeking patent protection for its inventions, it does not use its patent portfolio for the purpose of producing revenue by licensing; rather, it employs patents to protect its market position as a leading manufacturer of oscilloscopes. However, the plaintiff granted to the Western Electric Company and RCA a royalty-free license in its patents in return for a license in certain groups of patents of those firms. Plaintiff also licensed the Hewlett-Packard Company, a major competitor, with a royalty-free cross-license in all patents of each firm. The few instances in which plaintiff did enter into licenses, and the unique circumstances surrounding those licenses, lead to the conclusion that *302plaintiff has no discernible licensing policy upon which this court can predicate a "reasonable royalty.” Defendants concede this to be the fact.
6. Extensive testimony by Mr. E. E. Swanson, controller for plaintiff since 1961, as well as by others,, has satisfactorily established plaintiffs sales, its accounting procedures and methods, its cost-accounting techniques, its discount policies, its catalog prices, and, where necessary, the reason for the absence of certain records and the basis on which certain subsidiary records may be used to ascertain the needed information. This evidence establishes that:
(a) Plaintiffs policy was to sell its oscilloscopes to all customers, including defendant, at the catalog price less its standard discount. That discount policy provided no discount on the first nine units purchased, a 2% discount on the tenth unit through the twenty-fourth, a 4% discount for the twenty-fifth unit through the forty-ninth, and a 6% discount on all units beyond the forty-ninth. Plaintiffs catalog prices, which remained the same at all relevant times, were $1,400 for the 535, $1,550 for the 545, and $1,130 for the 516.
(b) Plaintiffs costs to produce scopes consist of material, labor, variable burden, and fixed burden. Fixed burden is the burden that does not vary with the volume of production but varies with or is related to a period of time. Fixed burden includes the capacity expenses and direct-period expenses of nonmanufacturing areas. Capacity expenses are the expenses associated with a general level of production or an ability or capacity to operate or produce at a certain level. Depreciation, insurance, and property taxes are capacity expenses and thus are part of fixed burden. Marketing, administration, and engineering expenses are direct period or fixed expenses and thus part of fixed burden.
(c) Other possible costs that may be incurred are expenses in making a sale, shipping, warehousing, field support, order processing, billing, carrying higher inventory, and accounts receivable.
(d) The difference between the selling price and the total variable cost or out-of-pocket cost is the contribution which a product makes toward fixed burden and profit.
(e) Sales to defendant have generally been about 10% of plaintiffs total sales. Even including indirect sales, defendant’s business has never exceeded 25% of plaintiffs total sales. If defendant had procured from plaintiff all of the nonmilitarized scopes, including plug-ins and accessories, that it procured from the third-party defendants, plaintiffs annual sales would have increased an average of *303approximately 3% during the period 1959-1966. The increase would not have exceeded 6% in any year. During the period 1959 to 1968, plaintiff sold 14,230 model 535 or 535A scopes and 20,485 model 545 and 545A scopes.
7. The evidence, including the testimony of plaintiffs witnesses Scott and Park, established that the increase in production required to fill the contracts for nonmilitarized scopes awarded to others could have been handled by plaintiff, with its existing facilities and personnel, either then currently employed or from a readily available labor pool. This was true throughout the period of infringement. The commercial models which plaintiff sold to its other customers would have met the requirements of defendant. However, plaintiff has failed to prove by clear and convincing evidence that, if the defendant had confined itself to authorized sellers, plaintiff would have actually made the sales to the Government which were made by the third-party defendants, or that if it had made such sales it would have made and retained the "lost” profits it seeks in the present suit.
8. Defendant’s gross cost for procuring the scopes, plug-ins, accessories, and spares under the 42 contracts was approximately $10,409,730. This represented a savings to defendant of more than $4,891,000, as compared to the cost of the scopes and plug-ins had they been procured from plaintiff. These contracts covered procurement of 9,105 scopes. Based on the scopes only, defendant’s procurement cost it $9,115,068, as compared to $12,542,617 at plaintiffs prices, a savings of $3,427,549 for defendant. For scopes and plug-ins together, excluding all else, defendant’s procurement costs were $9,740,385.
9. Based on the information available at trial, defendant, under 30 separate contracts, procured 8,437 militarized scopes from Hickok and Lavoie. These procurements were spread over the following period:
Year Oscilloscopes
1961 1,079
1962 645
1963 359
1964 1,609
1965 ' 639
1966 2,607
1967 1.499
Total 8,437
This represented a total procurement of $11,557,695, of which $7,829,772 was the cost of the scopes.
*30410. (a) Defendants concede there is no established royalty for the patents in this accounting. Defendant relies principally on certain commercial radio apparatus licenses granted by Radio Corporation of America (RCA), which licenses included oscilloscopes as one of the types of apparatus licensed. Plaintiff is a licensee of RCA under this type of license. The RCA license had a commercial royalty rate of VA% and a Government rate of 1%. Plaintiff also had a cross-license with Western Electric, which had a royalty rate of 2% on commercial sales and 1% on sales to the Department of Defense. Also in evidence is a Raytheon license with defendant which provided a sliding royalty ranging from 2% to 1% on subminiature tubes. Based on these licenses, defendant recommends a royalty program of 1.5% on the first $2 million of procurement, 1.2% on the next $3 million procurement, and 1% on the remainder, with the royalty base restricted to the scope, omitting all plug-ins, probes, accessories, packing, data, etc. Those figures would yield a total royalty of $185,445 for all of the scopes, both military and commercial, procured by defendant.
(b) The RCA, Western Electric, and Raytheon licenses on which defendant relies are not analogous to the situation present here. Each of those companies is, as compared to plaintiff, a corporate giant with a diverse product line and extensive patent portfolios. The licensing program of both RCA and Western Electric was in the context of an antitrust consent decree. The subminiatu-rized tubes of Raytheon are not in any way related to oscilloscopes. Items such as transistors, tubes, and similar electronic components have a relatively low per-unit cost but are sold and used in large quantity. That is distinguishable from an instrument such as an oscilloscope where the per-unit cost is much higher and the quantities sold are much lower. Defendants have not carried their burden of establishing any meaningful pattern of licenses, or royalty rates, that would be relevant in this case.
11. (a) Plaintiff offered the testimony of Elmer Gorn to assist the court in establishing a reasonable royalty rate to be used in determining the basic compensation due plaintiff for infringement on contracts involving the AN/USM-105, AN/USM-140, and AN/USM-141 scopes. Gorn proposed to establish a reasonable royalty on a "willing buyer-willing seller” model. That model contemplates a supposititious meeting prior to any infringement between the patent owner and the potential manufacturer of the infringing items in order to negotiate a license agreement. The prospective licensee and the prospective *305licensor in this hypothetical meeting would agree upon a royalty equal to the difference between the expected sale price and the expected cost of the infringing item minus the normal nonproprietary profit of the infringing manufacturer. In postulating what the potential licensor might suggest during the hypothetical meeting as his expected sale price of the infringing item, the actual sale price of the infringing item may be considered if it is reasonable and consistent with the assumptions and expectations of the parties governing the hypothetical negotiation. Where the patentee has manufactured the patented item and has adequate cost data with respect thereto and where the prospective licensee has not manufactured the patented item, the prospective licensee has not manufactured the patented item, the parties would adopt the patentee’s costs as a reasonable estimate of the prospective licensee’s costs. Those costs would include all of the factors thought necessary, i.e., materials, labor, variable manufacturing burden, fixed manufacturing burden, marketing expense, administration expense, and research and engineering expenses.
(b) This formula presented by plaintiff, when properly used, furnishes a good starting-point for the determination of a reasonable royalty which would be agreed upon by a "willing buyer” and "willing seller.”
12. (a) Cost/price studies were made by plaintiff during the period of 1959-1967. The purpose of these studies was to evaluate the profit performance of each product and to aid in pricing new products. These studies compiled actual manufacturing costs for each product sold by plaintiff; in addition, each product was allocated a certain percentage of the nonmanufacturing costs including research and development, marketing, and administration. The allocation is based on a percentage of the standard manufacturing cost of each product and merely represents a method of spreading these expenses across the entire product line. The "Total Company Cost” is a sum of both the actual costs for each product and the allocated costs assigned to that product. To determine the actual manufacturing costs for that product, the allocated costs should not be included.
(b) Plaintiffs cost for the model -545 scope during 1959 was $1019. That figure is based on the variable manufacturing cost of $486 plus $533 for fixed burden, marketing and administrative costs, etc. (including plaintiffs profit-sharing program).
(c) Hickok’s average profit during the period 1960-68 was 2.7%. In 1961, its profit was 4.7% of sales.
*306(d) Plaintiff has a profit-sharing program in which 35% of the profits each year is distributed to its employees.
13. The result of the formula described in finding 11, when appropriately applied to this case, leaves a residual share of 7.65% of unit price as royalty (or part of the royalty) for the plaintiff as the presumed willing seller. Based on all the considerations applicable to the case it is concluded, however, that 10% would be the reasonable royalty accepted by the supposititious willing seller and willing buyer.
14. (a) Where it is not practicable to determine with certainty the cost of portions of a device, the general practice in the electronics industry is to use the cost of the entire "black box” or device as a royalty base. If only a minor portion of the device is covered by the patent, a lower royalty rate in recognition of this fact is usually adopted. While, in the present case, less than the entire scope is covered by the patents in suit, the patented circuits cover the major elements that make the scope a success so no diminution in royalty would be appropriate.
(b) It is the practice in the industry to negotiate the base to which the royalty rate is to be applied. In some instances, unpatented items such as plug-ins and accessories are included in the base while, in other instances, they would be excluded. There is no exact formula for determining this, the practice varying from license to license. One reasonable approach is to include in the base everything required for an operative device, which, in this case, would include plug-ins, probes, and accessories. Another reasonable approach would be to exclude from the base all unpatented items which are readily separable and for which separate prices are readily ascertainable; this would exclude plug-ins, probes, and accessories. Items such as packing and instruction manuals are not normally included in the royalty base.
15. Hickok presented some cost estimates it had made in early 1961 for an unsuccessful bid on a contract for production of the 1805 scope. No records were produced by Hickok to show either what its actual costs were or what its actual profits were on the sale of these scopes. Nor did Hickok produce any estimated costs for any contracts actually awarded to it.
16. As a part of its periodic cost/price, studies, plaintiff projected, for each product, an anticipated profit margin as a percent of the catalog price. During 1961-67, those margins were:

At the rate of 10%, applied to a base of $21,298,080 ($9,740,385 for the "commercial” scopes plus plug-in accessories; $11,557,695 for "militarized” scopes plus plug-in accessories), the reasonable and entire compensation to plaintiff for the patents infringed amounts to $2,129,808 plus compensation for delay in payment.
18. Compensation for delay in payment shall be made at the rates prescribed in Pitcairn v. United States, 212 Ct. Cl. 168, 547 F. 2d 1106 (1976).
CONCLUSION OF LAW
Upon the foregoing findings of fact which are made a part of the judgment herein, the court concludes as a matter of law that plaintiff is entitled to recover the sum of $2,129,808 plus interest as part of just compensation. The exact amount of recovery will be determined under Rule 131(c).
Mr. Glassman based his testimony on eight criteria:
"Yes. I believe that there are eight pertinent criteria to be used here in determining a reasonable royalty. The first one is the degree of importance, or the advance over the prior art, to put it a little differently, of the patents on which the compensation is to be based.
"Second, the total volume of infringing procurement. Third, the portion of the device which utilizes the patents held valid and infringed. Fourth, whether the royalty base is to be the entire device or only a portion of it. Fifth, the features of the device or related items, such as accessories and data, whose costs are to be deducted in arriving at the royalty base. Sixth, the Court of Claims decisions, and to a lesser extent the decisions of other Federal Courts, on the determination of reasonable royalty rates. Seventh, any licenses which were granted by the Plaintiff under the patents before the filing of the suit. And finally, eight, typical license agreements on electronic testing and measuring apparatus under patents of other companies.” [Tr. 3843-3844.]

See Hearings on H.R. 5231 (later reported as H.R. 5311) Before the House Comm. on Patents, 79th Cong., 2d Sess. 2-3 (1946) (remarks of Rep. Henry explaining the prime reason for the elimination of infringer’s profits):
"Now, however, by far the greater number of patents that are in litigation are on special and often relatively insignificant parts of complex structures to which the patented feature is so related that it is absolutely impossible to apportion the profits due to the invention, those being the only profits to which the patentee is entitled.
"The result is that there is a complete failure of justice in almost every case in which supposed profits are recovered or recoverable.
"Absolutely artificial and unsound rules have been invented to solve the impossible problem of how to apportion profits.”
Portions of the hearing, including the above quotation and other pertinent information, are quoted at length in footnotes in Georgia-Pacific Corp. v. United States Plywood Corp., 243 F. Supp. 500, 521-527 (S.D. N.Y. 1965).
The majority in its footnote 7 states that:
"This willing-buyer/willing-seller technique in determining a reasonable royalty has not been a stranger to the Court of Claims. Olsson v. United States, supra; Badowski v. United States, 150 Ct. Cl. 482, 485, 278 F. 2d 934 (1960); Ushakoff v. United States, 179 Ct. Cl. 780, 785-86, 375 F. 2d 822, 825, 153 U.S.P.Q. 410 (1967); Amerace Esna Corp. v. United States, 199 Ct. Cl. 175, 462 F. 2d 1377, 174 U.S.P.Q. 517 (1972). For cases from other courts, see, e.g., Jenn-Air Corp. v. Penn Ventilator Co., 394 F. Supp. 665, 185 U.S.P.Q. 410 (E.D. Pa. 1975).”
None of the Court of Claims cases uses the infringer’s profit hypothetical approach. Olsson uses the willing buyer-willing seller approach using Government savings as a basis. In Badowski the willing buyer-willing seller approach was used using prior commercial licenses granted by the patent owner as a basis. In Ushakoff the willing buyer-willing seller approach was implemented using prior commercial licenses as a basis. Amerace Esna Corp. uses the willing buyer-willing seller approach using cost savings to defendant as a basis. Jenn-Air Corp. uses the willing buyer-willing seller approach but it was a damage determination under 35 U.S.C. § 284 and a suit between private parties; the federal rules of eminent domain are not applicable in such cases.
