This is an appeal from a decision of the Patent and Trademark Office (PTO) Trademark Trial and Appeal Board (board),1 in which the board (1) granted the motion of appellee-applicant (Hardigg) for partial summary judgment, (2) denied the motion of appellant-opposer (Toro) for summary judgment, and (3) granted Toro’s motion for suspension of proceedings. The board considered res judicata inapplicable. We reverse and remand.
Background
Hardigg filed application serial No. 341,-386 (application I) on October 22, 1969, seeking registration of TORO-PAD for “Plastic Pads for Absorbing and Otherwise Dissipating Shocks.” Toro opposed and adduced testimony. Hardigg took no testimony.2 The opposition was sustained, the board having found a likelihood of confusion in the simultaneous use of the marks on Hardigg’s goods as described and on Toro’s replacement shock absorbers. On June 19, 1972, Hardigg appealed to this court. We affirmed on January 17, 1974.3
On July 21, 1972, without notice to Toro, or to this court in which its appeal was pending, Hardigg filed the present application, serial No. 430,451 (application II), seeking registration of TORO-PAD for “Plastic Cushioning Pads for Bumpers and Packaging Applications,” alleging the same dates of use and submitting the same specimens (photos of pads bearing the mark) as in application I.
Application II was published for opposition on July 23, 1974. Toro opposed on September 13, 1974. Paragraph 8 of Toro’s notice of opposition claimed res judicata as a basis for sustaining the opposition. On April 11,1975, Toro sued Hardigg for trademark infringement and unfair competition in the federal district court in Minnesota. In the PTO, Toro filed a motion to suspend the present proceedings. Hardigg opposed the motion to suspend and filed a motion to strike paragraph 8 of the notice on the ground that res judicata was inapplicable. *787Toro filed, and Hardigg opposed, a motion for summary judgment based on res judicata.
The Board
The board characterized the board decision in the previous opposition as follows:
An examination of the Board’s decision in the previous opposition reveals that although applicant’s goods there involved were identified as plastic pads for absorbing and otherwise dissipating shocks, nevertheless when faced with evidence of opposer’s prior use of the mark “TORO” for, inter alia, replacement parts for lawn mowers, including shock absorbing devices, applicant sought to avoid a finding of likelihood of confusion by arguing that it, unlike opposer, sold its shock absorbing devices not to the home owner but to “packaging engineers and experts.” The Board, in rejecting applicant’s argument, pointed out not only that applicant had taken no testimony to establish the nature and use of its product or the class of purchasers for whom it was intended but also that applicant’s application contained no restrictions in these respects except to the extent that its product was described therein as being made of plastic. * * *
It then stated the res judicata issue in these terms:
As a result of that decision, applicant filed its present application to register the mark “TORO-PAD”, wherein its product, which is apparently the same product as that involved in applicant’s prior application, is identified more narrowly as “plastic cushioning pads for bumpers and packaging applications.”
Thus the basic question raised by the pending motions for summary judgment is whether the issue of likelihood of confusion presented in this proceeding, wherein applicant’s goods are described as “plastic cushioning pads for bumpers and packaging applications” was or could have been litigated in the prior opposition, wherein applicant’s goods were described more broadly as “plastic pads for absorbing and otherwise dissipating shocks.”
The board then stated that Hardigg could not have obtained consideration of its argument that its goods were not actually similar to Toro’s, even if Hardigg had submitted evidence thereof because “ * * * it is well established that the question of likelihood of confusion in a proceeding of this nature must be determined solely upon a consideration of the goods identified in applicant's application, regardless of the uses or specific nature thereof revealed by the evidence of record.” The board considered the rationale of that statement in numerous cited authorities to be the applicability of the presumptions of Section 7(b) of the Act of 1946 to all goods listed in the application. The board then said:
* * * In the same vein, the Board has on a number of occasions held that the identification of goods in an application involved in an opposition proceeding may not be amended in the absence of opposer’s consent thereto since opposer is entitled as a matter of right to a determination of the issues set forth in the pleadings, including the identification of goods in applicant’s application as published in the Official Gazette for opposition purposes. See, for example: Cool-Ray, Inc. v. Eye Care, Inc., 183 USPQ 618 (TT&A Bd., 1974), and Economics Laboratory, Inc. v. Estee Lauder Inc., 183 USPQ 443 (TT&A Bd., 1974).
The board held res judicata inapplicable on the view that “under the existing decisional law” Hardigg was bound in the first opposition by its description of goods and “thus could not obtain a determination of the issue of likelihood of confusion based on the asserted actual nature of its goods,” and that the present question of likelihood of confusion is thus one “which neither was nor could have been litigated in the prior opposition.”
Accordingly, the board granted Hardigg’s motion, in effect striking paragraph 8 (res judicata) from the notice, and denied Toro’s motion for summary judgment. Opposer’s *788motion to suspend was granted in view of Trademark Rule 2.117, 37 CFR 2.117.4
Issue
The dispositive issue is whether the board erred in holding res judicata inapplicable.
OPINION
Jurisdiction
Confessing inability to find authorities in point, Hardigg nonetheless expresses “doubt” concerning the jurisdiction of this court to entertain the present appeal. We hold jurisdiction present. In Knickerbocker Toy Co., Inc. v. Faultless Starch Co., 467 F.2d 501, 59 CCPA 1300 (1972), citing Gillespie v. United States Steel Corp., 379 U.S. 148, 85 S.Ct. 308, 13 L.Ed.2d 199 (1964), we looked to whether the goal of judicial economy would be truly served by allowance of the appeal and whether the cause left unadjudicated was sufficiently distinct from the claim stricken. Those questions being answered in the affirmative, we affirmed the action of the board in striking claims to copyright infringement and unfair competition from a petitioner/opposer’s cancellation and opposition pleadings and reversed its action in striking other claims.
As we recognized in Knickerbocker and more recently in SCOA Industries, Inc. v. Kennedy & Cohen, Inc., 530 F.2d 953, 189 USPQ 15 (Cust. & Pat.App.1976), the general proposition is that this court does not have jurisdiction over appeals from interlocutory orders of the board, or over a board decision striking some but not all of a party’s pleadings, or, as sometimes expressed, over decisions not “final.” United States Treasury v. Synthetic Plastics Co., 341 F.2d 157, 52 CCPA 967 (1965); Seamless Rubber Co. v. Ethicon, Inc., 268 F.2d 231, 46 CCPA 950 (1959); and Master, Warden, etc. v. Sheffield Steel Corp., 215 F.2d 285, 42 CCPA 726 (1954). In the present case, however, an early decision on res judicata would advance the goal of judicial economy, and the res judicata claim is, in our view, sufficiently distinct from the issue of likelihood of confusion to warrant the present appeal.
Like the situation in SCOA, proceedings have been suspended in the PTO. Hence a ruling by us on the propriety of the board’s summary judgment decisions would not promote justice by cutting off delay. Our ruling would, however, avoid the continuing pendency and possible conduct of an unnecessary and burdensome proceeding in the PTO. To force the same parties, even potentially, through a complete trial in a second proceeding involving the same marks and issues would be to nullify the judicial economy residing in our decision on the earlier appeal and defeat the goal of finality of litigation sought by the doctrine of res judicata. More importantly, unlike the situation in SCOA but like that in Knickerbocker, the res judicata issue is distinct and separate from the remaining issues in the notice of opposition. Indeed, in granting a motion by Toro to defer decision on the motion to suspend, pending determination of the motions for summary judgment, the board described the res judicata motions as “any outstanding motionfs] which may be dispositive of the case.” A ruling on res judicata is clearly among the class of matters described in Gillespie, supra, as “fundamental to the further conduct of the case,” 379 U.S. at 154, 85 S.Ct. at 312.
Applicability of Res Judicata
The res judicata issue is one of law and is determinable by a mere comparison of the descriptions of goods appearing in Hardigg’s two applications. The board read the second description as identifying Hardigg’s product “more narrowly.” We do not agree. The words which describe what the goods are and what they do, “plastic cushioning pads,” are not more narrow than the corresponding words, “plastic pads for absorbing and otherwise dissipating shocks.” Both phrases say the goods are “plastic *789pads.” The words regarding the function of the goods, “cushioning” and “absorbing * * * dissipating shocks,” are 'interchangeable. Thus Hardigg merely substituted synonyms in describing the goods and their function.
The words “for bumpers and packaging applications” do not restrict the nature or function of the goods, but merely indicate two possible places where the goods might be used. The goods remain precisely the same “cushioning” or “shock absorbing” pads previously described.5 Describing the goods in an application for trademark registration is not a semantic game and is not equatable to an effort to obtain the broadest possible claim in a patent application. The description of goods in a trademark registration neither expands nor limits a registrant’s right to use its mark or to exert any rights it may have against a user of the same or similar mark. A description including a limitation to specific trade channels limits only the exertion of the particular rights evidenced by the registration containing such description. See Commerce Drug Co. Inc. v. Kirkman Laboratories, Inc., 461 F.2d 833, 59 CCPA 1085 (1972).
Though we express no opinion on limitations which might avoid the effect of res judicata herein, we note that nothing in Hardigg’s application II limits use of its mark in connection with sales of its pads for use on bumpers or for use in packaging applications. Nothing therein indicates that its goods are specifically or solely designed for such use. Most importantly, nothing in the present description of goods limits their channels of trade. Hardigg argues as though the words of its present description were “plastic cushioning pads sold only for use in packaging applications,” but that is not the case. The board in the prior opposition held that the description therein of Hardigg’s goods “contained no restrictions” regarding sale to “packaging engineers and experts.” We detect no such restrictions in the present description. If “for packaging applications” be read to mean “sold only for use in packaging applications,” Hardigg’s description is still not restricted to packaging applications. It includes “bumpers,” which are shock absorbers and are encompassed within its earlier description.6
We do not hold, as Toro would apparently have us do, that identity of the goods is sufficient of itself to require invocation of the doctrine of res judicata. The rule is clear that registration must be determined in the light of an applicant’s goods as described in the application. But the goods must be those on which the mark is actually in use and must be accurately and truthfully described. 15 U.S.C. § 1051(a)(1). CTS Corporation v. Cronstoms Manufacturing, Inc., 515 F.2d 780, 185 USPQ 773 (Cust. & Pat.App.1975). Applicants may file new applications after adverse court decisions, but, as was said more than 60 years ago in D. H. Burrell & Co. v. Simplex Electric Heating Co., 44 App.D.C. 452 (1916), in an effort to arrest a “mischievous practice”:
After an applicant has been defeated in an opposition proceeding, he may be permitted. to amend his application, but he must eliminate therefrom every ground of controversy which was involved in the opposition proceeding, for, unless he does so, that proceeding is rendered abortive and a second controversy started over a question that the prior decision put at rest.
In the present case, Hardigg simply did not revise the description of its goods to *790limit their nature, function, use, or channels of trade, though, if the facts so warranted, it could have easily done so. Neither the goods nor their description being effectively changed, the issue remained unchanged, and Hardigg was not entitled to retry that issue by insisting upon the conduct of Toro’s present opposition to final determination.
Thus this second action between the parties was not on “a different cause or demand.” Commissioner of Internal Revenue v. Sunnen, 333 U.S. 591, 68 S.Ct. 715, 92 L.Ed. 898 (1947). Because “bumpers” are shock absorbers, and likelihood of confusion when the mark is applied to any of the goods described is sufficient, the board could have disposed of the case on the doctrine of collateral estoppel, the cause being unchanged and the “packaging” language being superfluous and irrelevant. The board did not, however, apply the doctrine of collateral estoppel to the dispositive issue, as it did to the priority and similarity-of-marks issues unquestionably tried in the prior action. Hence we treat of the reasoning below as it appears in the opinion supporting the appealed decision.
If it be thought that Hardigg’s present description does more narrowly describe its goods, the outcome is the same in this particular case. As the board recognized, the doctrine of res judicata means that parties to a suit and their privies are bound by the judgment of the court, not only with respect to every matter litigated but also with respect to every admissible matter which might have been offered to sustain or defeat a claim. Commissioner v. Sunnen, supra, at 597, 68 S.Ct. 715. The board thus considered that the dispositive question is whether the issue of likelihood of confusion between TORO on shock absorbers and TORO PAD on “plastic cushioning pads for bumpers and packaging applications” might have been litigated in the prior opposition.
As above indicated, the effective identity in breadth of the descriptions of goods would indicate that the issue was in fact litigated in the prior opposition. The description of Hardigg’s goods there involved was broad enough to encompass plastic pads capable of use in an infinite variety of shock absorbing applications. Because the present description merely says Hardigg’s goods are capable of use in two such applications and does not limit them to such use, the finding of likelihood of confusion in the prior opposition and affirmed by this court determined a “matter litigated” between the parties, making the first part of the doctrine of res judicata applicable.
However that may be, the doctrine is equally applicable in this case if attention be focused, as was the board’s, upon the second part of the doctrine, i. e., “matter which might have been offered.” It is clear that Hardigg could have litigated in the prior opposition the defense, if it had one, that its pads move in different channels of trade from those in which the shock absorbers of Toro move.7 It elected to submit no exhibits and to adduce no testimony in support of that defense.8
The board erred in its view that Hardigg could not have obtained consideration of its present contention in the prior opposition, even if it had submitted evidence in support thereof. That view was based on an erroneous linkup of two established rules: (1) that likelihood of confusion must be determined solely upon consideration of the goods identified in the application, and (2) that an applicant may not amend the description of goods without opposer’s con*791sent. The critical fact in this regard is Hardigg’s failure to submit its evidence and thereafter to seek appropriate amendment of its application in the prior opposition. It was error for the board to assume that opposer would have withheld consent to such amendment, and to conclude, on the sole basis of that assumption, that Hardigg was “bound by its broad identification of goods and thus could not obtain a determination of the issue of likelihood of confusion based on the asserted actual nature of its goods.”
It was Hardigg, not Toro, which precluded the opportunity for consideration of the true nature of Hardigg’s goods in the prior opposition. It will not do for a litigant to refrain, by choice, from even attempting to litigate a matter brought to its attention and clearly litigable without injury to itself in a first inter-partes proceeding and then, in a subsequent inter-partes proceeding against the same party, be relieved of the effect of res judicata on the ground that the matter could not have been litigated.9
The board stated, “To apply the doctrine of res judicata inflexibly in situations such as this would create an injustice in cases where an applicant's goods may in fact so differ from those in connection with which opposer uses its pleaded mark that there is no likelihood of confusion.” We think, on the contrary, that situations such as this, wherein all the evidence is that Hardigg’s goods do not in fact differ, and the only “difference” lies in the words of substantially equally unrestricted descriptions of goods, are precisely the type of situations requiring application of res judicata. To require an opposer, who had been successful in a prior opposition and appeal to this court, to undergo a second opposition proceeding and potential appeal solely because of insignificant word changes in the description of goods would defeat the goal of judicial economy and would work an injustice upon that opposer.
Accordingly, the decision of the board in which it granted Hardigg’s motion for partial summary judgment and denied Toro’s motion for summary judgment is reversed and the case is remanded for further proceedings consistent with this opinion.
REVERSED and REMANDED.
. 187 USPQ 689 (1975).
. Hardigg relied in this prior opposition on argument that its pads were sold only to “packaging engineers and experts.” The board correctly dismissed the argument for lack of support in the record.
. 180 USPQ 403 (1974).
. Hardigg did not appeal the grant of the motion to suspend. In view of our decision herein, and absent some consideration not here involved, it would appear that the opposition would be sustained upon remand and the matter of suspension would become moot.
. Hardigg’s brief is replete with statements that its second application relates to “different goods.” Its argument and case citations assume a difference in goods. Yet Hardigg has never submitted evidence tending to establish a difference in goods, despite numerous opportunities to do so. No affidavit was submitted in support of Hardigg’s motion to strike. The board referred to Hardigg’s product as “apparently the same product.” The specimens in both applications are photos of identical goods. It is clear that the only “difference” in the record is a change of words in the description of the goods.
. That bumpers are shock absorbers, is not denied by Hardigg, whose arguments ignore the point and concentrate on “packaging applications,” a tactic apparently successful below.
. Though Hardigg does not so argue, its case for non-likelihood of confusion necessarily rests, on this record, upon a difference in channels of trade. Conveniently ignoring “bumpers,” Hardigg would have us infer, from its mere addition of the phrase “and packaging applications,” that its goods are sold only to packaging engineers. See n. 2.
. The notion that an applicant may retain an unnecessarily broad description of goods while he employs the judicial process, at the expense of the taxpayers, to “try” the sole issue of dissimilarity of the marks alone, when an accurately amended description would have enabled trial of the whole case, is anathema to the doctrine of res judicata and to the goal of judicial economy it was designed to achieve.
. A situation distinguishable from the statutorily permissible refiling of ex parte applications for patent or trademark registration, after affirmance on appeal of a rejection in a first application. Even then, the applicant’s pocketbook and the imperative of judicial economy require maximum effort toward full consideration of as many apparent and alternative positions as possible in connection with the first application, and an applicant attempting to retread the same ground in a refiled application should anticipate the same result. The present situation is also distinguishable from that in which a properly broad description of goods overlaps with the goods of a prior user, and the applicant, having lost an appeal filed in the bona fide belief that the overlap would not be likely to lead to confusion, files an application containing a description of goods which unequivocally eliminates the overlap. In such event, the overlap issue was litigated and the amended description raised a new issue not litigable in the first proceeding, there being no provision for alternative descriptions in trademark applications.
