221 U.S.P.Q. 289
BALL CORPORATION, Appellee,
v.
The UNITED STATES, Appellant.
Appeal No. 84-680.
United States Court of Appeals,
Federal Circuit.
March 15, 1984.
Joseph A. Hill, Washington, D.C., for appellant.
Allen Kirkpatrick, Washington, D.C., for appellee.
Before BALDWIN, BENNETT and SMITH, Circuit Judges.
EDWARD S. SMITH, Circuit Judge.
This case presents the question whether a patentee is barred by the recapture rule from securing, through reissue, claims to subject matter previously canceled from the original application. Plaintiff-appellee, Ball Corporation (Ball), brought suit against the Government in the United States Court of Claims under 28 U.S.C. Sec. 1498(a) (1976) for unauthorized use of the invention claimed in U.S. patent No. Re. 29,296 (July 5, 1977) to Krutsinger, et al. (the Krutsinger patent). The Government moved for summary judgment and Ball filed a cross-motion for summary judgment. Both motions were denied.1 The Government appealed denial of its motion to this court. At the time of that first appeal, the judgment of the trial judge was not final and the issues had not been certified for appeal. In view of the uncertified, interlocutory nature of the appeal at that time, this court on March 30, 1983, issued an order dismissing the appeal for lack of jurisdiction with leave to seek certification and to appeal pursuant to 28 U.S.C. Sec. 1292(d)(2). On November 22, 1983, the trial judge certified the questions. Permission was granted on December 12, 1983, to take interlocutory appeal to this court. The Government again appeals. We conclude that the trial judge properly denied the Government's motion for summary judgment, and we remand the case for trial.
Background
The invention covered by the Krutsinger patent relates to a dual slot antenna assembly (Fig. 1) intended for use on missiles.
NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE
The antenna (Fig. 2) consists of two thin cylindrical concentric conductors [20, 24] assembled so that they are radially spaced slightly apart to form a cavity . The cavity may be void or may be filled with a dielectric material. The axial length of the conductors is substantially equal to one-half wavelength at the anticipated operating frequency of the antenna. The conductor assembly can be mounted around the outer skin of the vehicle (Fig. 1).
The circumferential edges of the cylindrical conductors define radiation slots [23, 25] (Fig. 3).
NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE
Because the cylindrical conductors are one-half wavelength long, these radiation slots are, ipso facto, longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna. The radiation slots are excited by signal energy from a source and cooperate to produce an omnidirectional dipole radiation pattern.2 Due to the one-half wavelength spacing between the radiation slots, the electromagnetic radiation emanating from the slots [R1 , R2 ] radiates in the same direction and overlaps in an additive manner to provide a stronger radiation pattern.
Signal energy is supplied to the antenna by a connector (Fig. 4).
NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE
In the preferred embodiment of the invention, the connection of the inner and outer cylindrical concentric conductive elements to the source is accomplished by means of a single coaxial transmission feedline. It is this feedline element around which the present controversy revolves. In particular, this case involves the number of feedlines to the outer conductor that may be properly claimed in the Krutsinger reissue patent in light of the prosecution history of the original patent application.
The Canceled Claims
Dependent claims 8 and 9 are the only claims of the original application critical to this appeal. Claim 8 includes the single feedline, whereas claim 9 does not. Claim 8 calls for "at least one" conductive lead to be connected to the edge of one of the conductors. Claim 9 requires that "a plurality of leads" be connected to the edge of one of the conductors at circumferentially spaced intervals.
In the first office action on the original application the examiner rejected claims 1-8 and indicated that claims 9 and 10 should be limited to a plurality of feedlines. The claims were amended and, on July 14, 1972, the examiner made his second rejection final. The examiner again suggested the allowability of the plurality of feedlines claims if presented in independent form. The remaining claims were rejected over the newly cited reference, Cork, U.S. patent No. 2,234,234. The Cork patent discloses a single feedline (Fig. 5) and is similar in all other material respects to Krutsinger's antenna.
NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE
Following the second office action, Ball added limitations to the claims requiring that a plurality of leads be connected to an edge of the outer conductor. These leads were recited to be spaced-apart at intervals substantially equal to one wavelength at the anticipated operating frequency of the antenna. Ball also canceled claim 7 and dependent claim 8 (the canceled claims), of the original application, which are set forth below:
7. A dual slot antenna assembly comprising: a first substantially cylindrical conductor, the axial length of which is approximately equal to one-half wavelength at the anticipated operating frequency of said assembly; a second substantially cylindrical conductor, the axial length of which is at least equal to the axial length of said first conductor, said second conductor being positioned concentrically within and radially spaced from said first conductor so as to define a pair of circumferential slots spaced one-half wavelength apart at said anticipated operating frequency and providing independent radiation patterns emanating in the same direction; and electrical signal feed means connected with said conductor for electrically exciting both of said slots.
8. An assembly according to Claim 7 wherein said feed means includes at least one conductive lead which terminates connected to the edge of one of said conductors defining one of said slots.
U.S. patent No. 3,810,183 (the original patent) issued on May 7, 1974, to Ball as assignee, on the basis of the original application, as amended.
Subsequently, Ball decided that it was entitled to claims broad enough to include the single feedline. On July 16, 1975, within the 2-year statutory period for broadened reissue provided in 35 U.S.C. Sec. 251, Ball filed a reissue application. Claims 1-4 of the reissue application comprised the four claims of the original patent. New claims 5-7 were added to the reissue application. Only the new claims, 5-7, directed to the single feedline embodiment, are in issue in this proceeding.3
The Alleged Error
In support of its reissue application Ball stated that the original patent was partially inoperative because it claimed less than Ball had a right to claim. Ball identified as error the undue limitation of the claims of the original patent to a plurality of feedlines:
[T]he unwarranted limited scope of our original patent claims were errors [sic] that arose without any deceptive intention as a result of inadequate and/or ineffective communication with our former patent attorney, * * * and/or as a result of an inadequate understanding on our part of the potential effect of recitations in the original patent claim language under United States laws; * * *4
U.S. patent No. Re. 29,296 issued on July 5, 1977, on the basis of the reissue application.
The Reissue Claims
Ball filed an administrative claim with the United States Navy on January 18, 1978, seeking damages and compensation for unauthorized use of, inter alia, the invention covered by claims 5, 6, and 7 of U.S. patent No. Re. 29,296. Claims 5, 6, and 7 of the reissue patent are set forth below:
5. A dual slot antenna assembly comprising:
a pair of laterally spaced-apart conductive elements separated with respect to one another by a sheet of dielectric material,
one of said conductive elements being of larger dimensions and underlying the other element and defining an electrical reference or ground surface;
said conductive elements defining a pair of radiation slots between opposing edges of said other element and said reference surface, said radiation slots being longitudinally spaced-apart a predetermined distance approximately equal to one-half wavelength at the anticipated operating frequency of said assembly,
each of which radiation slots emanates radiation therefrom such that the radiation patterns developed are in substantially the same direction;
said radiation slots having a length dimension equal to the entire length of said opposing edges, which length dimension is greater than the spacing between said conductive elements; and
a single electrical signal feed assembly integrally connected with said other conductive element at only one of said opposing edges for electrically exciting both of said radiation slots from a single signal feed junction.
6. An assembly according to claim 5 wherein said conductive elements and said sheet of dielectric material each comprise part of a single sheet of dielectric material metallically cladded on opposite sides thereof.
7. An antenna structure comprising:
an electrically conducting ground surface,
a single layer electrically conducting surface comprising both an r.f. radiator conducting area and an r.f. feedline conducting area integrally connected thereto and formed therewith,
a dielectric sheet disposed between said ground surface and the single layer electrically conducting surface,
said conducting surfaces defining a pair of radiation slots between opposing edges of said r.f. radiator and said ground surface, said radiation slots being longitudinally spaced apart by a predetermined distance approximately equal to one-half wavelength at the anticipated operating frequency of said antenna structure;
each of which radiation slots emanates radiation therefrom such that radiation patterns developed are in substantially the same direction;
said radiation slots having a length dimension equal to the entire length of said opposing edges, which length dimension is greater than the spacing between said surfaces; and
said r.f. feedline being connected to the outside edge of one only of said opposing edges of said r.f. radiation conducting area to at least one predetermined point on the periphery of said radiator conducting area. [Emphasis in original.]
On March 25, 1981, Ball filed a petition in the United States Court of Claims under 28 U.S.C. Sec. 1498 (1976),5 seeking reasonable and entire compensation for the "infringement" of claims 5, 6, and 7 of U.S. patent No. Re. 29,296. On June 29, 1981, prior to filing an answer, the Government moved for summary judgment. Ball filed a cross-motion for summary judgment.
Judge Colaianni denied both motions. As to the Government's motion, denial of which is on appeal here, the trial judge found that the undisputed evidence of record did not support the Government's arguments; as to Ball's cross-motion, the trial judge found that material issues of fact remained which compelled denial of the motion. Because we agree that neither the recapture rule nor the estoppel doctrine mandate grant of the Government's summary judgment motion, we affirm.
Issues
Two issues are raised in this appeal: (1) whether the error alleged by Ball is sufficient as a matter of law under 35 U.S.C. Sec. 251 (1976) to support reissue; and (2) whether Ball is estopped from securing, through reissue, claims covering the single feedline feature.
The Government contends that Ball's deliberate cancelation of the single feedline claims was not error. That act was taken to avoid a prior art rejection and, in the Government's view, the recapture rule bars Ball from securing similar claims through reissue. The Government also contends that the deliberate nature of Ball's acts estops Ball from securing similar claims through reissue. Ball did not appeal the denial of its summary judgment motion but, rather, defends the trial judge's opinion as correct as a matter of law. Resolution of this controversy involves a substantial body of precedent.6 The parties differ in their interpretation of the law and in their application of it to the facts of this case.
The Recapture Rule
Reissue is not a substitute for Patent Office appeal procedures. Reissue is an extraordinary procedure and must be adequately supported by the circumstances detailed in 35 U.S.C. Sec. 251 (1976)7 and in the implementing regulations, 37 C.F.R. Sec. 1.175 (1982). The Government asserts that the nature of error that will justify reissue is narrowly circumscribed to ensure that reissue remains the exception and not the rule. Relying on Edward Miller & Co. v. Bridgeport Brass Co.,8 the Government contends that "a mere error of judgment" is not adequate to support reissue; rather the error must be "a real bona fide mistake, inadvertently committed."
The 1952 revision of the patent laws made no substantive change in the definition of error under section 251.9 While deliberate cancellation of a claim cannot ordinarily be considered error,10 the CCPA has repeatedly held that the deliberate cancellation of claims may constitute error, if it occurs without deceptive intent.11 In In re Petrow,12 the CCPA went so far as to state that error is sufficient where the deliberate cancellation of claims does not amount to an admission that the reissue claims were not patentable at the time the original claims were canceled. Similarly, in In re Wesseler,13 the CCPA stated that error is established where there is no evidence that the appellant intentionally omitted or abandoned the claimed subject matter. Thus, the CCPA has construed the term error under section 251 broadly.14
The Ninth Circuit employed a more rigid standard in Riley v. Broadway-Hale Stores, Inc.15 stating: "when the chief element added by reissue has been abandoned while seeking the original patent, the reissue is void." The trial judge sought to determine whether Ball had made a deliberate judgment that claims of substantially the same scope as the new reissue claims would have been unpatentable. The Government, arguing from Riley, submits that the trial judge's approach loses sight of the feature given up by a patentee in order to secure the original patent. We decline to adopt the rigid standard applied in Riley, in favor of the more liberal approach taken by the CCPA. Petrow clearly establishes the vitality of the standard employed by the trial judge under this court's precedent.
Further, the Government argues that we need not reach the issue of claim scope because the sufficiency of error is a threshold issue. While claim scope is no oracle on intent, the Government fails to apprehend its role. Rarely is evidence of the patentee's intent in canceling a claim presented. Thus, the court may draw inferences from changes in claim scope when other reliable evidence of the patentee's intent is not available. Claim scope is not the lodestar of reissue. Rather, the court's reliance on that indicator in the case law appears to be born of practical necessity as the only available reliable evidence.
The Government relies heavily on Haliczer v. United States,16 which also involved a suit under 28 U.S.C. Sec. 1498. The Court of Claims in that case held the reissue claims invalid because the patentee sought to acquire through reissue the same claims that had earlier been canceled from the original application. The recapture rule bars the patentee from acquiring, through reissue, claims that are of the same or of broader scope than those claims that were canceled from the original application.17 On the other hand, the patentee is free to acquire, through reissue, claims that are narrower in scope than the canceled claims.18 If the reissue claims are narrower than the canceled claims, yet broader than the original patent claims, reissue must be sought within 2 years after grant of the original patent.
Thus, the applicability of the recapture rule and the sufficiency of error under section 251 turn in this case, in the absence of other evidence of the patentee's intent, on the similarity between the reissue and the canceled claims. Narrower reissue claims are allowable; broader reissue claims or reissue claims of the same scope as the canceled claims are not.19 The subject matter of the claims is not alone controlling.20 Similarly, the focus is not, as the Government contends, on the specific limitations or on the elements of the claims but, rather, on the scope of the claims.21Ball's Reissue Claims
The trial judge required the Government to establish that the applicant has made a deliberate decision that the canceled claims are unpatentable. The Government argues that that standard is not correct because it loses sight of the feature that the patentee gave up during prosecution of the original application. We find the Government's argument entirely unpersuasive. The proper focus is on the scope of the claims, not on the individual feature or element purportedly given up during prosecution of the original application. The trial judge quite properly focused on the scope of the claims and we find no error in this respect. He determined that the reissue claims were intermediate in scope--broader than the claims of the original patent yet narrower than the canceled claims.
The alleged inadequacy of Ball's proffered error is not as clear as the Government contends. The error supporting reissue submitted by Ball comports with the statute and regulations. Further, we fail to perceive the "inconsistency" of Ball's position as asserted by the Government.
The canceled claims, claims 7 and 8,22 define the invention quite broadly. Canceled claim 8 requires feed means including at least one conductive lead. The reissue claims,23 in contrast, include limitations not present in the canceled claims: the cavity is filled with a dielectric material; and an electrical signal feed assembly replaces the feed means of the canceled claims. The electrical signal feed assembly (Fig. 6) is a network of leads with a single coaxial feedline to that network. The network consists of a plurality of thin ribbon-like conductive leads.
NOTE: OPINION CONTAINS TABLE OR OTHER DATA THAT IS NOT VIEWABLE
Feed points to the outer conductor are one wavelength apart at the anticipated operating frequency of the antenna. The leads of this network [52, 54, 56, 58] are dimensioned to provide continuous impedance matching between the cavity and the single coaxial feedline , which feeds into the assembly at the aperture . The signal feed assembly is more limited than the "at least one" feed means limitation of canceled claim 8.
The reissue claims are, however, broader in one respect. The canceled claims are limited to an antenna of cylindrical configuration, whereas the reissue claims are not so limited. We are aware of the principle that a claim that is broader in any respect is considered to be broader than the original claims even though it may be narrower in other respects.24 That rule will not bar Ball from securing the reissue claims here on appeal.
Pursuant to section 251, broadened reissue must be sought within 2 years after issuance of the original patent. The CCPA, in In re Rogoff,25 noted that section 251
contains no exceptions or qualifications as to time or extent of enlargement. The sole issue, therefore, is whether the claims on appeal enlarge, i.e., broaden, the patent claim.
It is well settled that a claim is broadened, so far as the question of right to reissue is concerned, if it is so changed as to bring within its scope any structure which was not within the scope of the original claim. In other words, a claim is broadened if it is broader in any respect than the original claim, even though it may be narrowed in other respects. * * *
Thus, the principle that a claim is broadened if it is broader in any respect than the original claim serves to effect the bar of section 251 against reissue filed later than 2 years after issuance of the original patent. In this case, Ball filed its application for reissue within the 2-year period for broadened reissue specified in section 251.
We know of no authority applying the above rule to reissue claims relative to the scope of canceled claims within the 2-year period for broadened reissue. Nor do we perceive the wisdom of such extension in this case. The rule is rigid and properly so in that it effects an express statutory limitation on broadened reissue. The recapture rule, however, is based on equitable principles. The rigidity of the broader-in-any-respect rule makes it inappropriate in the estoppel situation presented in this appeal.
Hence, we decline to apply that rule here, where the broader feature relates to an aspect of the invention that is not material to the alleged error supporting reissue. In Willingham, the CCPA reversed the rejection of a claim that was narrower than the canceled claim as to one element, although broader as to another element. "The extent to which [deliberate cancellation of a claim from the original application] may also prevent [a patentee] from obtaining other claims differing in form or substance from that cancelled necessarily depends upon the facts in each case and particularly on the reasons for the cancellation."26 Accordingly, we hold that the reissue claims are not substantially identical in scope to the canceled claims.
As noted supra, there is widespread agreement that reissue claims that are narrower than the canceled claims are allowable. In In re Wadlinger,27 the CCPA faced a situation in which the reissue claims were, as the trial judge found here, of "different" scope from the canceled claims. While both the reissue and canceled claims were directed to the same process in Wadlinger, the canceled claims were considered broader, resulting in claims of different scope. The reissue claims were held valid. Similarly, we find that the non-material, broader aspects of Ball's reissue claims do not deprive them of their fundamental narrowness of scope relative to the canceled claims. Thus, the reissue claims are sufficiently narrower than the canceled claims to avoid the effect of the recapture rule.
Estoppel
The Government also argues that Ball is estopped to secure the reissue claims. We do not consider this argument as stating an independent ground for relief. The recapture rule is a creature of equity and it embodies the estoppel notions which the Government now urges upon us.28 We have already resolved this issue against the Government.
We agree with the patentee that the Government's "file wrapper estoppel" argument is equally unavailing. The doctrine of estoppel based on the prosecution history is a corollary to the doctrine of equivalents, a tool in the analysis of infringement. The parties are before this court purely on a controlling issue of law relative to the validity of the reissue claims being asserted by Ball. There has not yet been a full trial on the issue of infringement, let alone on the validity of the reissue claims.29 The Government's estoppel argument does no more than restate the basic equitable principles underlying the recapture rule.
Conclusion
The trial judge properly articulated the law governing reissue. While broader in scope than the original claims, the reissue claims are narrower in scope than the canceled claims. The error supporting reissue appears to be sufficient. On the basis of the facts before us and the reasons given for the cancellation of the claims from the original application, we cannot find, as a matter of law, that Ball is barred from securing reissue claims drawn to the single feedline embodiment of its invention. The case is remanded to the Claims Court for further proceedings consistent with this opinion.
AFFIRMED AND REMANDED.
On October 8, 1982, pursuant to this court's order of October 4, 1982, Judge Colaianni of the U.S. Claims Court entered a judgment denying both parties' motions for summary judgment, corresponding to his earlier report in the case, filed by him as a trial judge of the U.S. Court of Claims on August 23, 1982
Previous missile antennas exhibited signal nulls that made monitoring difficult from a ground tracking station as the missile rolled or changed direction in flight. The claimed antenna exhibits a substantially isotropic radiation pattern which overcomes this problem by eliminating signal nulls

The Government apparently misconstrues Haliczer in this respect. In Haliczer, the court determined that the doctrine of equivalents would require that the original claims, carried over into the reissue patent, would not be entitled to the range of equivalents that were purposely surrendered during prosecution of the original patent.

There is no inconsistency in arguing the broadened scope of the reissue claims and, thus, no estoppel
