InterGlobe Technologies v. Zynga: Federal Circuit Affirms Patent Unpatentability
InterGlobe Technologies, SA asserted US8795064B2, covering a method and apparatus for outputting messages at a game machine, against Zynga. After 669 days before the Federal Circuit, the court affirmed the underlying unpatentability finding — extinguishing the patent’s enforceability.
Federal Circuit closes the door on InterGlobe’s game machine patent
InterGlobe Technologies, SA, a patent-holding entity, brought appeal No. 23-2263 before the Court of Appeals for the Federal Circuit on August 10, 2023. The dispute centred on US8795064B2, a patent directed to a method and apparatus for outputting a message at a game machine. The underlying challenge was an invalidity/cancellation action on patentability grounds, with the Patent Trial and Appeal Board’s determination forming the decision under review.
On June 9, 2025, the Federal Circuit issued an affirmance, upholding the PTAB’s finding that the claims of US8795064B2 are unpatentable. For InterGlobe, the affirmance means the patent is cancelled and no longer enforceable against Zynga or any third party. For Zynga, the ruling eliminates the litigation risk associated with this patent and validates its challenge strategy, which was handled by Orrick Herrington & Sutcliffe LLP.
The 669-day duration suggests the Federal Circuit undertook careful review, consistent with technically complex patentability appeals. What drove the PTAB’s original invalidity finding — whether prior art, obviousness, or written description — is not specified in the public record. The affirmance forecloses further Federal Circuit review, leaving only a potential Supreme Court petition as a theoretical avenue for InterGlobe, which would face very long odds.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means the lower tribunal’s ruling survives without modification
When the Federal Circuit affirms, it finds no reversible error in the decision below — here, the PTAB’s determination that US8795064B2 is unpatentable. The appellate court is not conducting a fresh patentability analysis; it reviews for legal error and whether substantial evidence supports the PTAB’s factual findings. An affirmance carries the full weight of finality at this court level.
Appellate affirmanceUS8795064B2 is cancelled — InterGlobe loses all enforcement rights
For InterGlobe Technologies, the affirmance is a terminal outcome. The patent is unpatentable and cancelled, meaning it cannot be asserted against Zynga or any other party. InterGlobe’s investment in Baker & Hostetler’s appellate team did not yield a reversal. The only remaining theoretical avenue would be a petition to the Supreme Court, though such petitions in patent validity cases face extremely low grant rates.
Patent cancelledZynga’s IPR or PGR strategy fully vindicated at the Federal Circuit
Zynga, represented by Orrick Herrington & Sutcliffe, successfully defended the PTAB’s unpatentability finding through Federal Circuit review. The affirmance eliminates this specific patent as a future litigation threat not only for Zynga but for any competitor in the game machine or digital gaming space. Zynga’s approach — challenging patentability at the PTAB rather than litigating validity in district court — proved commercially effective.
Full appellate victoryCancelled game-machine patent reduces assertion risk across the gaming sector
With US8795064B2 cancelled, companies operating in the digital gaming and game machine messaging space face one fewer patent assertion risk. The Federal Circuit’s affirmance strengthens the precedent that PTAB invalidity findings will be upheld absent clear legal error. For gaming companies evaluating their FTO position, this outcome suggests that proactive PTAB challenges remain a reliable defensive tool against non-practising entity assertions in this technology area.

Official order — verbatim text
The single-word verdict ‘AFFIRMED’ is the Federal Circuit’s definitive statement that the PTAB’s unpatentability determination contained no reversible legal error and was supported by substantial evidence. Under the appellate standard of review, the court defers to PTAB factual findings unless clearly erroneous. The basis of termination recorded as ‘Unpatentable’ confirms claim cancellation. For InterGlobe, this forecloses any further Federal Circuit relief; for Zynga, it provides finality against this patent assertion.
US8795064B2 — Method and apparatus for outputting a message at a game machine
US8795064B2, filed under application number US13/680852, covers a method and apparatus for outputting a message at a game machine. The patent sits at the intersection of gaming device hardware and interactive messaging functionality — a technical domain that has grown in commercial significance as digital and online gaming platforms have scaled. The patent’s claims were ultimately found unpatentable by the PTAB, a determination the Federal Circuit has now affirmed.
For the gaming sector, this patent’s cancellation removes a potential IP barrier in the game machine messaging space. The patent had been asserted by InterGlobe Technologies, a non-practising entity, against Zynga — one of the largest social gaming companies globally. The cancellation signals that the claimed methods and apparatus lacked the patentability criteria to survive inter partes review or post-grant challenge scrutiny, which has broader implications for similar claims in the NPE portfolio landscape targeting game machine technology.
Should you run an FTO against US8795064B2?
US8795064B2 has been cancelled following Federal Circuit affirmance of PTAB unpatentability — it is no longer enforceable. However, game machine and digital gaming companies should not stop at this single patent. InterGlobe Technologies may hold related patents, continuations, or divisionals covering similar game machine messaging methods. Any company developing game machine software, in-game notification systems, or digital messaging features integrated into gaming platforms should audit the surrounding patent landscape.

What this case signals for the digital gaming IP landscape
The Federal Circuit’s affirmance in InterGlobe v. Zynga reinforces two durable patterns: PTAB unpatentability findings are hard to reverse on appeal, and NPE assertions in gaming face robust institutional challenges.
PTAB cancellations are highly durable at the Federal Circuit
The Federal Circuit applies a deferential substantial-evidence standard to PTAB factual findings. This case is consistent with the general pattern in which affirmed PTAB unpatentability determinations survive appeal at a high rate. Companies defending against patent assertions should weight PTAB proceedings heavily in their strategic calculus.
NPE enforcement risk in game machine technology is materially reduced
US8795064B2 is no longer available as an assertion tool. Any licensing programme built around this patent must now be unwound. Competitors and licensees who may have been paying royalties or negotiating under threat of this patent should reassess their positions in light of the cancellation.
InterGlobe v Zynga — key questions answered
The Federal Circuit affirmed the PTAB’s unpatentability finding for US8795064B2 on June 9, 2025 in case No. 23-2263. The patent, covering a method and apparatus for outputting a message at a game machine, was cancelled. InterGlobe Technologies, represented by Baker & Hostetler, could not secure a reversal of the underlying PTAB determination.
An affirmance of a PTAB unpatentability ruling means the patent claims are cancelled and no longer enforceable against any party — not just Zynga. US8795064B2 cannot be asserted in future litigation. Any existing licensing agreements or negotiations premised on this patent’s validity should be reassessed in light of the cancellation.
The public record does not specify Zynga’s strategic rationale, but PTAB proceedings typically offer a faster and lower-cost path to patent cancellation compared to district court invalidity litigation. A successful PTAB cancellation — as achieved here — eliminates the patent entirely rather than producing a case-specific invalidity finding, providing broader protection across the gaming sector.
The patent at issue is US8795064B2, filed under application number US13/680852. It covers a method and apparatus for outputting a message at a game machine. The patent was asserted by InterGlobe Technologies, SA — a non-practising entity — against Zynga in an invalidity/cancellation action on patentability grounds.
The Federal Circuit reviews PTAB legal conclusions de novo and PTAB factual findings under the substantial evidence standard. An affirmance indicates the court found no reversible legal error and that the record supported the PTAB’s unpatentability determination. The deferential standard applied to factual findings makes reversing PTAB cancellations challenging for patent holders on appeal.
