`Case 3:10-cv-00954-MO Document 524 Filed 06/04/14 Page 2 of 3
`
`MOSMAN, J.,
`
`EVE-USA, Inc., and Synopsys Emulation and Verification S.A. (collectively,
`
`“Synopsys”) move for partial summary judgment on Mentor Graphics Corporation’s (“Mentor
`
`Graphics”) counterclaims in case no. 13-579 on grounds of claim preclusion. (Mot. [371] at 2.)1
`
`I took the motion under advisement [416] after hearing oral argument on September 24, 2013.
`
`On March 5, 2014, I ordered [482] supplemental briefing on the question whether the ZeBu
`
`emulators at issue in Mentor Graphics’s counterclaims are “essentially the same” as those it
`
`accused of patent infringement in a 2006 action against EVE-USA, Inc. Mentor Graphics’s
`
`supplemental brief also raises the issue of whether, in light of recent Federal Circuit opinions, the
`
`claim preclusion inquiry no longer turns on whether the presently and formerly accused products
`
`are “essentially the same.” (Supp. Opp. [490] at 2–4.) I now GRANT Synopsys’s motion.
`
`For at least two decades, the Federal Circuit has held that judgment on a claim of
`
`infringement against a product bars a later infringement claim against a different product if the
`
`two products are “essentially the same.” Nystrom v. Trex Co., Inc., 580 F.3d 1281, 1285 (Fed.
`
`Cir. 2009); Roche Palo Alto LLC v. Apotex, Inc., 531 F.3d 1372, 1379 (Fed. Cir. 2008); Foster v.
`
`Hallco Mfg. Co., Inc., 947 F.2d 469, 479–80 (Fed. Cir. 1991). By contrast, in two recent, three-
`
`judge panel opinions, the court has held that claim preclusion does not bar an infringement claim
`
`against a product that did not exist as of the prior judgment, “essentially the same” or not. Brain
`
`Life, LLC v. Elekta Inc., 746 F.3d 1045, 1054 (Fed. Cir. 2014); Aspex Eyewear, Inc. v. Marchon
`
`Eyewear, Inc., 672 F.3d 1335, 1342 (Fed. Cir. 2012). Synopsys correctly observes that the
`
`Foster line of cases cannot be reconciled with Aspex and Brain Life. (Supp. Resp. [502] at 2–3.)
`
`Because one three-judge panel cannot overrule another, Newell Cos., Inc. v. Kenny Mfg. Co., 864
`
`F.2d 757, 765 (Fed. Cir. 1988), Foster controls until the Federal Circuit sitting en banc says
`
`1 All docket numbers refer to the lead case, no. 10-954.

`

`Case 3:10-cv-00954-MO Document 524 Filed 06/04/14 Page 3 of 3
`
`otherwise. Mentor Graphics’s counterclaims are barred if they accuse products that are
`
`“essentially the same” as those accused in the 2006 action.
`
`The evidence that the parties have presented permits only one conclusion: the presently
`
`and formerly accused ZeBu emulators are “essentially the same.” Mentor Graphics identifies
`
`only two new features of the modern emulators: a user-friendly software tool for generating
`
`“transactors” called ZEMI-3 and a device allowing multiple ZeBu units to function as a single
`
`emulator called Fast Internal Bus. (Supp. Opp. [490] at 6–9.) Synopsys correctly observes that
`
`neither of these features materially alters the manner in which the newer ZeBu emulators
`
`allegedly practice Mentor Graphics’s patents. (Supp. Resp. [502] at 6–9.)
`
`Synopsys’s Motion for Partial Summary Judgment [371] is GRANTED. Claim
`
`preclusion bars Mentor Graphics’s counterclaims [382] to the extent that they allege
`
`infringement of U.S. Patent Nos. 6,009,531 and 5,649,176.
`
`IT IS SO ORDERED.
`
`DATED this 4th day of June, 2014.
