Gamevice Eyes Supreme Court Cert Petition Over Procedural Contradictions in Nintendo Switch Patent Case

The long-running patent dispute between Gamevice, Inc. and Nintendo Co., Ltd. over handheld gaming accessories reached a new stage in April 2026, with Gamevice indicating on April 23 that it is considering filing a petition for certiorari to the U.S. Supreme Court. The case, Federal Circuit Case No. 24-1467, has attracted attention from patent practitioners for the procedural contradictions that emerged when the district court simultaneously found that the Nintendo Switch did not infringe Gamevice’s patents and that the Nintendo Switch anticipated — and thus invalidated — those same patents.

Background

Gamevice holds patents relating to grip-style gaming accessories that attach controllers to both sides of a tablet device. The company sued Nintendo in the Northern District of California, alleging that the Nintendo Switch infringed those patent claims. The district court entered summary judgment on two issues: first, that the Nintendo Switch does not infringe Gamevice’s patent claims; and second, that the Nintendo Switch constitutes prior art that renders those same patent claims invalid. The logical tension between these two holdings became the central procedural controversy of the appeal.

Federal Circuit Proceedings

In January 2026, the Federal Circuit affirmed the district court’s ruling in Case No. 24-1467. The panel directed Nintendo to file a motion in district court to vacate the anticipation findings. Gamevice challenged this approach, arguing that the Federal Circuit relied on a representation made by Nintendo during oral argument rather than on an established procedural basis. On March 23, 2026, the en banc Federal Circuit declined to rehear the case.

April 2026 Developments

On April 6, 2026, Nintendo filed a motion in the Northern District of California seeking to vacate the portions of the judgment containing the anticipation findings. On April 20, Gamevice filed its response opposing Nintendo’s motion. Gamevice pointed to two procedural defects. First, Federal Rule of Civil Procedure 59 requires motions to alter or amend a judgment to be filed within 28 days of the judgment. Second, Gamevice argued that the Federal Circuit’s reliance on Nintendo’s oral argument representations to structure a remand exceeded the court’s statutory jurisdiction under 28 U.S.C. § 1295(a)(1), which limits Federal Circuit jurisdiction to final decisions of district courts in patent cases.

Gamevice further argued that allowing contradictory noninfringement and invalidity findings to coexist creates a patent-specific exception to the doctrine of judicial estoppel, which normally prevents a party from advancing contradictory legal positions. The filing disclosed that Gamevice is considering a certiorari petition to the Supreme Court on these procedural grounds.

Significance for Patent Practice

The coexistence of noninfringement and invalidity findings is not inherently improper — defendants routinely plead both in the alternative. The issue here is the downstream procedural treatment: once both findings are entered and affirmed, it is unclear which constitutes a binding final judgment for collateral estoppel purposes, and whether a remand instruction predicated on an oral argument representation provides an adequate procedural foundation for post-judgment modification. If the Supreme Court grants certiorari, the decision could clarify how Federal Circuit remand authority interacts with district court judgment rules in patent cases.
