Wildcat Licensing v. Atlas Copco & GM: Federal Circuit Affirms Unpatentability
Wildcat Licensing asserted two reissue patents covering multi-location fastening-process monitoring against Atlas Copco, Magna International, Faurecia, and General Motors. The Federal Circuit affirmed the unpatentability finding across both patents in a case that ran 743 days from filing to close.
Automotive assembly-line patents cancelled on appeal
Wildcat Licensing, LLC, a patent assertion entity, appealed to the U.S. Court of Appeals for the Federal Circuit (Case No. 22-1303) after its two reissue patents — RE47220 and RE47232 — were found unpatentable at the proceeding below. The patents-in-suit claim methods for monitoring that fasteners are correctly applied at multiple assembly locations, technology directly relevant to high-volume automotive and industrial manufacturing lines operated by defendants Atlas Copco Tools and Assembly Systems, LLC, Magna International, Inc., Faurecia Automotive Seating, LLC, and General Motors, LLC.
The Federal Circuit issued its order on January 9, 2024, affirming the unpatentability determination on both asserted patents. An affirmance at this level means the appellate court found no reversible legal or factual error in the decision below, leaving the cancellation of RE47220 and RE47232 intact. For Wildcat Licensing, the ruling extinguishes the enforceable patent rights that formed the basis of its infringement claims against the four defendants.
The 743-day duration from filing (December 27, 2021) to close suggests the parties engaged in substantial appellate briefing, consistent with the complexity of patentability challenges involving reissue patents. Reissue proceedings introduce additional scrutiny around whether the broadening or correction of original claims introduced new invalidity issues. The public record does not disclose whether any licensing negotiations occurred in parallel or whether further en banc or Supreme Court review was sought.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means the lower unpatentability finding stands
When the Federal Circuit affirms, it concludes there was no reversible error — legal or factual — in the tribunal below. The appellate court does not retry the case; it reviews whether the correct legal standards were applied and whether factual findings were supported by substantial evidence. An affirmance of an unpatentability ruling gives that determination the same force as the original cancellation decision, with appellate authority behind it.
No reversible error foundWildcat Licensing loses both reissue patents permanently
With the Federal Circuit affirming unpatentability, Wildcat Licensing’s RE47220 and RE47232 are cancelled and unenforceable. The company cannot assert these patents in any parallel or future district court proceedings. Absent a successful petition for en banc rehearing or certiorari — both statistically rare — the cancellation is final. The ruling effectively ends the patent monetisation strategy built around these fastening-method claims.
Patent rights extinguishedAtlas Copco, Magna, Faurecia, and GM walk away clear
The four defendants — spanning industrial tooling and automotive manufacturing — secured a complete defence at the appellate level. With unpatentability affirmed, they face no infringement liability on these specific claims and no obligation to design around or license the patents. The affirmance also raises the bar for any related patent family members Wildcat Licensing might hold, since the underlying invalidity reasoning now carries Federal Circuit imprimatur.
Full appellate defence confirmedStrengthened invalidity precedent for assembly-monitoring methods
The affirmance signals that multi-location fastening-process monitoring claims — at least as drafted in RE47220 and RE47232 — did not survive patentability scrutiny. For OEMs and tier-1 suppliers investing in smart assembly and torque-monitoring systems, this removes a specific assertion risk. Competitors and tooling vendors operating in this space should still monitor any continuation or divisional applications in Wildcat’s portfolio, as those claims may be drafted differently.

Official order — verbatim text
The order’s language — ‘AFFIRMED’ without qualification — indicates the Federal Circuit adopted the unpatentability conclusion in full, without remand or partial reversal. At the appellate level, affirmance on a patentability question typically reflects the court’s application of the substantial-evidence standard to factual findings and de novo review of legal conclusions such as claim construction. The unqualified single-word disposition suggests no contested claim term or procedural issue survived to require further proceedings below.
RE47220 & RE47232 — Multi-location fastening-process monitoring methods
US RE47220 and US RE47232 are reissue patents — a USPTO mechanism that allows correction or broadening of an originally granted patent under 35 U.S.C. § 251. Both patents claim methods for monitoring that an article of assembly is properly fastened at more than one location, a capability central to quality assurance on high-throughput automotive assembly lines. The reissue applications were filed in 2017 (US15/425946 and US15/452306 respectively), suggesting Wildcat sought to adjust claim scope from an earlier patent grant to better capture commercially deployed fastening-verification technology.
In automotive and industrial manufacturing, multi-location fastening verification is a critical error-proofing layer — preventing under-torqued bolts, missed fasteners, or sequencing errors that can cause safety recalls. The patents’ relevance to Atlas Copco’s assembly tooling and GM’s/Faurecia’s/Magna’s production operations explains why defendants contested them vigorously. With both patents now cancelled by Federal Circuit affirmance, the claims no longer represent a licensing or litigation threat — but the underlying technical space remains subject to third-party patents from other holders active in torque-control, poka-yoke, and smart-assembly domains.
Should you run an FTO against RE47220 and RE47232?
For R&D teams and product managers developing fastening-verification systems, multi-station assembly monitoring tools, or torque-management platforms, RE47220 and RE47232 are now cancelled and need not be designed around. However, Wildcat Licensing may hold related applications, and the broader fastening-method patent landscape includes active filings from Atlas Copco, Bosch Rexroth, and other tier-1 tooling OEMs. Any FTO analysis for this product category should extend beyond just these two cancelled patents.

What this case signals for the automotive assembly IP landscape
The Federal Circuit’s affirmance in Wildcat v. Atlas Copco carries implications beyond the four named defendants for anyone in smart manufacturing and fastening systems.
Reissue patent claims face heightened invalidity scrutiny
Reissue patents — granted to correct or broaden original claims — attract additional invalidity arguments, including recapture doctrine and intervening rights. This case’s outcome suggests practitioners should critically evaluate the robustness of reissue claim scope before asserting or licensing such patents in high-value manufacturing contexts.
PAE assertions against tier-1 auto suppliers carry coalition risk
The alignment of Atlas Copco, Magna, Faurecia, and General Motors as co-defendants created a well-resourced, coordinated defence. Patent assertion entities targeting automotive manufacturing ecosystems should anticipate defendants pooling resources and mounting comprehensive invalidity challenges through inter partes review or other proceedings.
Wildcat v Atlas — key questions answered
The Federal Circuit affirmed the unpatentability of both asserted patents — RE47220 and RE47232 — in Case No. 22-1303, closing on January 9, 2024. The affirmance means the lower tribunal’s cancellation decision stands, and Wildcat Licensing cannot enforce these patents against Atlas Copco, Magna, Faurecia, GM, or any other party.
Both are U.S. reissue patents claiming methods for monitoring the proper fastening of an article of assembly at more than one location. Reissue patents are granted by the USPTO to correct or broaden original patent claims under 35 U.S.C. § 251. The underlying technology relates to multi-station fastening verification used in automotive and industrial assembly processes.
The public record identifies ‘Unpatentable’ as the basis of termination, consistent with a finding in an inter partes review or similar validity proceeding. The specific grounds — such as anticipation or obviousness over prior art — are not detailed in the available case data. The Federal Circuit’s affirmance confirms the lower determination was supported by sufficient evidence and correctly applied legal standards.
The defendants were Atlas Copco Tools and Assembly Systems, LLC (industrial assembly tooling), Magna International, Inc. (tier-1 automotive supplier), Faurecia Automotive Seating, LLC (automotive seating manufacturer), and General Motors, LLC (vehicle OEM). All four were represented through Pillsbury Winthrop Shaw Pittman LLP at the appellate stage.
With unpatentability affirmed and no indication of en banc or certiorari petitions in the public record, RE47220 and RE47232 are effectively cancelled. Wildcat cannot assert these specific patents. However, if Wildcat holds related continuation or divisional applications with differently drafted claims that survived or were not challenged, those could potentially be asserted separately — making a family tree review advisable for companies in the fastening-verification space.
