IOENGINE v. Ingenico: Federal Circuit Partly Reverses PTAB on Tunneling Access Patent
IOENGINE, LLC challenged PTAB’s unpatentability rulings against its US9774703B2 patent covering tunneling client access point technology, with Ingenico, Corp. defending the inter partes review outcome. After 1,255 days, the Federal Circuit reversed the Board on select claims while affirming unpatentability on the remainder — a split result that preserves partial patent protection for IOENGINE.
Split Federal Circuit ruling rescues select tunneling patent claims
IOENGINE, LLC brought this appeal to the United States Court of Appeals for the Federal Circuit (Case No. 21-1332), challenging the Patent Trial and Appeal Board’s determination that claims of its US9774703B2 patent — directed to an apparatus, method and system for a tunneling client access point — were unpatentable. The appeal also implicated related claims in what the court references as the ‘969 patent and the ‘703 patent, both part of the same tunneling access point technology family. The case was filed on 25 November 2020 and ran for 1,255 days before resolution on 3 May 2024.
The Federal Circuit issued a reversed-in-part, affirmed-in-part decision. The court reversed the Board’s unpatentability determinations as to claims 4 and 7 of the ‘969 patent and claims 61–62 and 110–11 of the ‘703 patent, meaning those specific claims survive and are not cancelled. All other challenged claims were affirmed as unpatentable, leaving them invalidated. The basis of termination also notes the appeal was dismissed in part, consistent with the partial disposition. For IOENGINE, the outcome preserves a narrowed but enforceable set of claims; for Ingenico, the majority of the originally invalidated claims remain cancelled.
A 1,255-day appellate timeline is consistent with complex inter partes review appeals at the Federal Circuit, where technical claim construction and prior art issues typically drive extended briefing. The split outcome suggests the court found meaningful patentable distinctions in the reversed claims not present in the broader claim set — though the public record does not reveal the specific prior art combinations or claim differentiation arguments that proved decisive. Whether IOENGINE pursues further enforcement on the surviving claims, or Ingenico seeks en banc or Supreme Court review, remains an open question from the available record.

Federal Circuit reverses-in-part: what the split ruling means for both parties
Reversed-in-part means the Board’s errors were real but limited
A ‘reversed-in-part, affirmed-in-part’ disposition at the Federal Circuit means the court identified specific legal or factual errors in the PTAB’s analysis — but only as to the enumerated claims. The Board’s unpatentability findings on those claims lacked sufficient support under the appellate standard of review. All remaining claims were found free of reversible error and their unpatentability stands. This is not a wholesale vindication of IOENGINE’s patent portfolio.
Partial reversal — select claims surviveIOENGINE retains enforceable claims — but a narrowed arsenal
The reversal on claims 4 and 7 of the ‘969 patent and claims 61–62 and 110–11 of the ‘703 patent restores their validity, making them once again enforceable against potential infringers. IOENGINE can resume or initiate licensing discussions or litigation on those surviving claims. However, the affirmance of unpatentability on the broader claim set significantly constrains enforcement leverage. The commercial value of the patent family depends heavily on the scope of the surviving claims relative to commercially relevant implementations.
Partial patent survival confirmedIngenico wins on most claims — but faces residual exposure
Ingenico secured affirmance of unpatentability across the majority of challenged claims, which is a substantial win in an IPR appeal context. However, the reversal on six enumerated claims means Ingenico retains exposure to patent infringement claims on those surviving claims. If Ingenico’s products or services fall within those claims, a new district court action remains possible. Further appellate options — en banc rehearing or certiorari — are technically available but face a high bar given the mixed outcome.
Majority of claims cancelled; residual risk remainsSplit outcomes reinforce the value of granular claim-by-claim IPR strategy
This outcome illustrates that Federal Circuit appeals of PTAB decisions routinely produce split results, making claim-level analysis essential for both challengers and patent holders. Companies in the tunneling client access point and connected device sectors should assess whether their implementations touch the surviving claims specifically. The decision also signals that the Federal Circuit is willing to correct discrete PTAB errors even within otherwise affirmed invalidity rulings — a reminder that IPR appeal is not merely a long shot for patent owners.

Official order — verbatim text
The court’s ‘reversed-in-part, affirmed-in-part’ disposition reflects a claim-specific appellate review applying the substantial evidence standard to the PTAB’s factual findings and de novo review to legal conclusions such as claim construction. By reversing only the enumerated claims — 4 and 7 of the ‘969 patent and 61–62 and 110–11 of the ‘703 patent — the Federal Circuit signals those claims presented a materially different record before the Board, likely distinct prior art mapping or claim construction outcomes. The explicit rejection of IOENGINE’s remaining arguments confirms the court conducted a full merits review before reaching this split disposition.
US9774703B2 — Tunneling Client Access Point Apparatus and System
US9774703B2 (application number US14/721540) claims an apparatus, method and system for a tunneling client access point — technology directed at enabling secure or structured data tunnelling through client-side access point hardware. The patent sits at the intersection of network connectivity, portable device architecture, and secure data transmission. Its application lineage and the involvement of both a ‘969 and ‘703 patent number suggests a family of related continuations, which is typical of portfolio strategies in the connected device and peripheral hardware space.
This patent family carries strategic weight in the payment terminal and IoT device sectors, where tunnelling architectures underpin secure communication between peripheral access points and backend systems. Ingenico’s involvement as an IPR petitioner — a major payment hardware vendor — underscores the commercial relevance of the technology. With select claims now reinstated, the patent represents a live enforcement asset that could implicate a range of connected device manufacturers, payment terminal OEMs, and secure access point technology providers beyond Ingenico alone.
Should you run an FTO analysis against US9774703B2?
Any R&D team or product manager working on tunneling client access point technology, portable secure access hardware, or connected payment device architectures should treat US9774703B2 as a live risk following this Federal Circuit ruling. Claims 4, 7, 61–62, and 110–11 are now valid and enforceable. Even if your product was cleared based on PTAB cancellation, the reversal means that clearance may no longer hold for the surviving claims.

What this case signals for the connected device and access point IP landscape
A split Federal Circuit ruling in an IPR appeal reshapes enforcement risk for tunneling access point technology across the payment and connected device sectors.
Surviving claims demand immediate FTO analysis for payment terminal makers
Any company producing or integrating tunneling client access point technology — particularly in the payment device and IoT connectivity space where Ingenico operates — should immediately assess whether their products fall within claims 4, 7 of the ‘969 patent or claims 61–62, 110–11 of the ‘703 patent. These claims are now valid and enforceable following the Federal Circuit’s reversal.
IPR petitioners should not treat PTAB wins as final without Federal Circuit review risk
This case confirms that PTAB unpatentability determinations are not immune from reversal at the Federal Circuit, even on a selective claim-by-claim basis. Companies relying on IPR outcomes to clear the path for product launch or market entry should factor in appellate reversal risk and monitor appeal filings by patent owners before treating IPR cancellation as definitive.
