U.S. Ethernet Innovations, LLC (“USEI”) appeals the decision of the United States District Court for the Eastern District of Texas, holding U.S. Patent No. 5,434,872 (“'872 patent”) invalid as anticipated on the basis of collateral estoppel, U.S. Ethernet Innovations, LLC v. Texas Instruments, Inc., No. 6:11-cv-491, 2015 WL 1001637 (E.D.Tex. Feb. 19, 2015) (“TI ”), following a final judgment of invalidity issued by the United States District Court for the Northern District of California, U.S. Ethernet Innovations, LLC. v. Acer, Inc., No. 4:10-cv-3724 (N.D.Cal. Oct. 10, 2014) (“Acer”), affirmed in Appeal No. 2015-1640, -1641 (Fed.Cir. April 25, 2016) (“Acer appeal”). USEI also contends that the district court erred by not allowing USEI to present its willful infringement argument. Because our contemporaneous affirmance of the Northern District’s summary judgment of invalidity of the '872 patent in the companion Acer appeal has issue-preclusive effect, we are compelled to affirm and do not reach USEI’s argument on willfulness.

BACKGROUND

In 2009, USEI sued several computer makers and Ethernet end-users in the Eastern District of Texas for infringement of the '872 patent, U.S. Patent No. 5,732,-094, and other patents no longer at issue. Those cases were transferred to the Northern District of California, and are the subject of the companion Acer appeal.

On September 15, 2011, USEI initiated the present action against Texas Instruments (“TI”) in the Eastern District of Texas for infringement of the '872 patent and other patents no longer at issue. On April 3, 2014, the district court heard and denied a motion by TI for summary judgment of invalidity of the '872 patent as anticipated by a SONIC reference. On April 11, 2014, a jury determined that all of the asserted claims of the '872 patent were not invalid over SONIC. On June 20, 2014, a second jury determined that TI directly infringed and induced infringement of all asserted claims of the '872 patent, and awarded USEI $3,000,000 in damages. On the basis of these jury determinations, the district court entered final judgment for USEI on September 19, 2014. In that judgment, the district court noted: “With the exception of the parties’ post-verdict briefing (Doc. Nos. 346, 348, 421, and 426 [including TI’s Rule 50(b) motion for judgment as a matter of law]), which will be ruled upon separately, all relief not previously granted is hereby DENIED.”

On November 7, 2014, Acer moved for summary judgment of invalidity in the Northern District of California case on the same SONIC reference previously found not to anticipate the claims of the '872 patent in the Eastern District of Texas case. The Northern District of California granted the motion and found the asserted claims of both the '872 and '094 patents invalid as anticipated. The court entered final judgment of invalidity on December 1, 2014.

Following the judgment of invalidity in the Northern District of California case, TI filed a motion in the Eastern District of Texas to compel the application of collateral estoppel and to enter judgment of invalidity of the '872 patent, notwithstanding the earlier contrary judgment entered on the basis of the jury’s verdict. On February 19, 2015, the TI district court granted TI’s motion. The TI district court did not rule on TI’s Rule 50(b) motion for judgment as a matter of law.

USEI challenges the Eastern District of Texas’s application of collateral estoppel in light of the timing of the district court ruling in the Acer case and timely appeals. We have jurisdiction under 28 U.S.C. § 1295(a)(1).

Discussion

USEI argues that Fifth Circuit law not Federal Circuit law governs the question of whether collateral estoppel may be applied after verdict and judgment in the Eastern District of Texas case on the basis of the inconsistent later judgment in the Northern District of California case. See Cycles, Ltd. v. Navistar Fin. Corp., 37 F.3d 1088, 1090 (5th Cir.1994) (holding a district court judgments final and, thus, “strong enough to withstand preclusion by inconsistent later judgments” even when the precluded judgment was not yet ap-pealable). We need not resolve this question, however, because we have contemporaneously affirmed the invalidity of the '872 patent in the Acer appeal, and that ruling itself has issue-preclusive effect. On issues of issue preclusion that implicate the scope of our own previous decisions, we apply Federal Circuit law. See Soverain Software LLC v. Victoria’s Secret Direct Brand Mgmt., LLC, 778 F.3d 1311, 1314 (Fed.Cir.2015) (“We apply this court’s precedent to questions involving substantive issues of patent law, issues of issue preclusion that implicate substantive patent law issues, or issues of issue preclusion that implicate the scope of our own previous decisions.”).

Our decision in Mendenhall v. Barber-Greene Co., 26 F.3d 1573, 1576-76 (Fed.Cir.1994) (“Mendenhall ”) informs the outcome in this case. That decision flowed from a series of cases in which patentee, Mendenhall, sued Astee, Cedarapids, and Barber-Greene, respectively, for infringement of the same patents in various district courts. The Astee case was the first to proceed to trial and resulted in a determination that the patents were not invalid. On September 1, 1989, this court affirmed the no invalidity ruling on interlocutory appeal and remanded for a determination of damages. See Mendenhall v. Astee In dus., Inc., 887 F.2d 1094 (Fed.Cir.1989) (unpublished), aff'g 13 U.S.P.Q.2d 1913, 1988 WL 188449 (E.D.Tenn. Oct. 31, 1988).

The Cedarapids case was the next to proceed to trial, resulting in a final judgment of invalidity on March 4, 1991. This court affirmed the invalidity determination on September 13, 1993. See Mendenhall v. Cedarapids, Inc., 5 F.3d 1557, 1574 (Fed.Cir.1993), cert. denied 511 U.S. 1031, 114 S.Ct. 1540, 128 L.Ed.2d 192 (1994).

Following the invalidity ruling in the Cedarapids case, Astee, in the remand proceedings, argued that Mendenhall was collaterally estopped on the basis of Cedar-apids. The Astee district court disagreed and proceeded to award damages. Astee then appealed.

In the Barber-Greene case, the district court held that Barber-Greene had infringed, and Barber-Greene appealed. The Cedarapids district court decision issued and we affirmed, while Barber-Greene’s appeal was pending. For the first time on appeal, Barber-Greene argued that the infringement determination and injunction should be reversed, based on the invahdity determination in Cedara-pids. Mendenhall, 26 F.3d at 1576. The Astee and Barber-Greene appeals were consolidated. Id. Mendenhall argued “that these cases [Astee and Barber-Greene ] are too far along for [the accused infring-ers] to invoke collateral estoppel.” Id. at 1578.

We disagreed and held that “[i]t would be contrary to the policies expressed in Blonder-Tongue were this court now to enter the judgments Mendenhall seeks in these appeals.” Id. In Blonder-Tongue, the Supreme Court held that non-mutual issue preclusion was generally available to accused infringers where a prior judgment had held that the asserted patent was invalid. Blonder-Tongue Labs., Inc. v. Univ. of Ill. Foundation, 402 U.S. 313, 350-51, 91 S.Ct. 1434, 28 L.Ed.2d 788 (1971). The Court reiterated that “[a] patent by its very nature is affected with a public interest,” id. at 343, 91 S.Ct. 1434 (quoting Precision Instrument Mfg. Co. v. Automotive Maint. Mach. Co., 324 U.S. 806, 816, 65 S.Ct. 993, 89 L.Ed. 1381 (1945)), and explained its “consistent view” “that the holder of a patent should not be ... allowed to exact royalties for the use of an idea that is not in fact patentable or that is beyond the scope of the patent monopoly granted,” such as would occur where a defendant must defend a suit for infringement of a previously adjudged invalid patent, see id. at 350-51, 91 S.Ct. 1434.

Mendenhall is squarely on point here. Like the precluding invalidity determination in Cedarapids, the precluding Acer decision was made and affirmed by this court. Just as Barber-Greene was not immunized from the preclusive effect of Cedarapids while Barber-Greene was on appeal after the district court’s final judgment, the TI decision here is likewise not immunized from the preclusive effect of the Acer appeal. See also Soverain, 778 F.3d at 1315 (“It is also established that issue preclusion applies even though the precluding judgment [ ] comes into existence while the case as to which preclusion is sought (this case) is on appeal.”). The invalidity of the '872 patent has been adjudged — to enforce it against TI in light of our concurrent affirmance in Acer would thus extend the patent beyond its proper scope.

USEI does not argue that it did not have a full and fair opportunity to litigate the validity of the '872 patent in Acer. Instead, USEI attempts to distinguish Mendenhall by asserting that the precluding judgment in that decision was a decision of this court, not a district court decision. Now that we have upheld the invalidity of the '872 patent, this argument is inapposite. Cf. Hart Steel Co. v. R.R. Supply Co., 244 U.S. 294, 299, 37 S.Ct. 506, 61 L.Ed. 1148 (1917) (“The conclusion [of patent invalidity] which we have reached in [the companion] Railroad Supply Co. v. Elyria Iron & Steel Co. this day decided 244 U.S. 285, 37 S.Ct. 502, 61 L.Ed. 1136 .., is such that it leaves our decision in this case [to apply collateral estoppel] uncomplicated by the one in that.”); R.R. Supply Co. v. Elyria Iron & Steel Co., 244 U.S. 285, 37 S.Ct. 502, 61 L.Ed. 1136 (1917).

“[A] patentee, having been afforded the opportunity to exhaust his remedy of appeal from a holding of invalidity, has had his ‘day in court’ and should not be allowed to harass others on the basis, of an invalid claim.” Blonder-Tongue, 402 U.S. at 339, 91 S.Ct. 1434; see also Mendenhall, 26 F.3d at 1578 (“For this court to affirm the findings of infringement and the willfulness of conduct against one appellant, increase damages' against the other, and uphold injunctions against both, appears anomalous in the extreme in connection with patents this court has just held invalid.”). There is no basis for USEI to avoid the application of estoppel in this case.

In short, this court’s affirmance in the Acer appeal of the Northern District of California’s judgment that all of the asserted claims of the '872 patent are invalid compels our affirmance of the Eastern District of Texas’s judgment under the circumstances of this case.

AFFIRMED.
