Arachnid, Inc., appeals the judgment entered on a jury verdict by the United States District Court for the Western District of Washington holding, inter alia, that U.S. Patent No. 4,793,618 (the ’618 patent) is invalid or unenforceable and not infringed, and that the defendants (collectively Medalist) аre not liable under the Washington Consumer Protection Act (WCPA). We affirm.
After the jury trial, Arachnid moved for judgment notwithstanding the verdict, and for a new trial, on the invalidity/unenforce-ability and non-infringement issues. In its February 15, 1991 and July 2, 1991 orders, the district court denied Arachnid’s motions for JNOY and a new trial, respectively. Because neither order discussed the issue of infringement, we must assume that the court concluded that the jury’s finding of non-infringement was supported by substantial evidence and not against the clear weight of thе evidence. On appeal, Arachnid argues that the district court erroneously denied these post-trial motions. It also contends that the jury’s verdict that Medalist is not liable under the WCPA is inconsistent with the factual findings it made as to liability for trade drеss infringement.
I.
A. As to the district court’s denial of Arachnid’s post-trial motions, we reverse a denial of a motion for JNOV only if the jury’s factual findings, presumed or express, are not supported by substantial evidence or, if they are, that the legal conclusion^) implied from the jury’s verdict cannot in law be supported by those findings.
Perkin-Elmer Corp. v. Computervision Corp.,
*1302 B. The issue of infringement turns on the scope of claim 1, which states, in рertinent part:
An electronic dart game apparatus ... comprising ... a first electronic memory storage area containing algorithms for scoring one or more different dart games wherein the value of points earned in а particular turn of said one or more different dart games is dependent upon the scoring segments hit during previous player turns....
Arachnid contends that electronic dart game machines like the alleged infringing machines that score both рoint dependent and non-point dependent dart games infringe claim 1. Thus, in finding non-infringement, the jury must have construed the claim as limited to machines that score point dependent games only. The question before us is whether that construction was proper.
Claim scope is determined not only by the claim language, but also by examining the specification and the prosecution history.
ZMI Corp. v. Cardiac Resuscitator Corp.,
In this case, there is substantial evidence from whiсh a jury could find that the examiner rejected the claim as Arachnid construes it. During prosecution the examiner rejected claim 1 as first amended. The applicant and examiner then agreed that the subject matter of then claim 14 would be incorporated into claim l. 1 Pursuant to this agreement the applicant filed a second amended claim 1 which clearly covered both point dependent and non-point dependent games. 2 The examiner rejected this language, suggested the language that appears in the issued claim, and allowed the claim. Since the allowed claim does not clearly allow for both point dependent and non-point dependent games, a jury сould reasonably find that the examiner allowed a claim limited to a memory storage area containing point dependent games only. Such a finding is supported by the specification, which discloses point dependent dart gаmes only and describes no embodiment of any machine containing both point dependent and non-point dependent games.
Based on the disclosure in the specification, and the prosecution history described above, we agree with the district court’s ruling on the JNOV motion that there was substantial evidence supporting facts from which the jury could conclude that claim 1 covered electronic dart machines that play point dependent games only. Accordingly, we affirm the district court’s denial of Arachnid’s motion for JNOV for infringement. For similar reasons, we do not find that the district court abused its discretion in denying Arachnid’s motion for new trial on the issue of infringement.
C. Arachnid also objects to the district court’s denial of its post-trial motions on the invalidity/unenforceability issue. In a thorough and well-reasoned opinion, the district court concluded that there was substantial evidence to support at least four of *1303 the asserted grounds for finding the pаtent invalid or unenforceable. We have closely examined the court’s reasoning and the record, and we discern no error in the court’s conclusions.
Arachnid argues that even if most of the possible grounds for the invalidity/unenforceability verdict are supported by substantial evidence, we must order a new trial on the invalidity/unenforceability issue if any one of the possible grounds is unsupported by substantial evidence. However, Arachnid delayed raising this “general-verdict-multiрle-defenses” (GVMD) argument until five months after it filed its post-trial motions. Arachnid contends that under
Roy v. Volkswagen-werk Aktiengesellschaft,
II.
Arachnid’s final argument is that the portion of the judgment entered pursuant to the jury’s general verdict that Medalist was not liable under the WCPA violates Fed.R.Civ.P. 49(b). Rule 49(b) states, in pertinent part:
When the answers [to special interrogatories] are consistent with each other but one or more is inconsistent with the general verdiсt, judgment may be entered pursuant to Rule 58 in accordance with the answers, notwithstanding the general verdict, or the court may return the jury for further consideration of its answers and verdict or may order a new trial.
Fed.R.Civ.P. 49(b).
The judgment violates Rule 49(b), Arachnid argues, because the jury’s WCPA general verdict in favor of Medalist is inconsistent with special interrogatories that underlie the jury’s general verdict in favor of Arachnid on its claim for trade dress infringement.

In support of this argument, Arachnid cites
Nordstrom, Inc. v. Tampourlos,
Medalist argues on two grounds that Arachnid waived its right to object on appeal to the portion of the judgment relating to its WCPA claim. First, Medalist argues that Arachnid waived its right because it failed to raise the alleged inconsistency before the jury was discharged. In the alternative, Medalist argues that Arachnid *1304 waived its right because it failed to raise the alleged inconsistency in either of its post-trial motions.
Because “the issue of inconsistent jury findings is a procedural matter not unique to patent law ... we apply the discernable law of the forum.”
Beckman Instruments, Inc. v. LKB Produkter AB,
Ninth Circuit law is less clear with respect to Medalist's second waiver argument. In attempting to refute Medalist’s second argument, Arachnid quotes from
Pierce v. Southern Pacific Transp. Co.,
When no post-trial motions have been made, aрpellate review of judgments entered pursuant to a jury trial is limited.
See Johnson v. New York, N.H. & H.R. Co.,
AFFIRMED.
Notes
. At the time of this rejection, claim 1 stated:
An electronic dart game apparatus ... comprising ... a first electronic memory storage area containing rules and instructions for one or more different dart games individually selectable for play by one or more of said players. ...
Claim 14 stated:
An electronic dart game apparatus as claimed in claim 1 wherein said different dart games include inter-player dependent games wherein the scoring of one plаyer is dependent upon the scoring segments hit during previous turns.
. Applicant amended claim 1 to state:
An electronic dart game apparatus ... comprising ... a first electronic memory storage area containing algorithms for scoring one or more different dart games where at least one of said different dart games provides for scoring that is dependent upon the scoring segments hit during previous player turns.
. Arachnid refers to the special interrogatories as special "verdicts." The distinction between special verdicts and special interrogatories is unclear.
