Arctic Cat Inc. v. Gep Power Products, Inc., 919 F.3d 1320

Background

Arctic Cat owns U.S. Pat. Nos. 7,072,188 (’188) and 7,420,822 (’822) claiming a power-distribution module with an array of receptacle openings and a distribution harness; the ’822 is a continuation of the ’188 application (priority Oct. 29, 2002).
GEP petitioned for inter partes review of all claims of both patents, asserting anticipation and obviousness grounds (including reliance on U.S. Patent No. 6,850,421 (Boyd)). The PTAB found all claims unpatentable and expunged a full inventor deposition transcript Arctic Cat later filed.
Key claim-construction dispute: whether preamble language referencing a “personal recreational vehicle” limits certain claims of both patents.
Key prior-art dispute: whether Boyd (filed Apr. 1, 2002) is § 102(e) prior art against the patents, which claim priority to Oct. 29, 2002 — resolution turns on whether Arctic Cat’s inventor (Janisch) antedated Boyd by conception and continuous/diligent reduction to practice.
The PTAB (1) rejected the late-submitted full deposition transcript, (2) held the vehicle-referencing preambles non-limiting for the challenged claims, and (3) treated Boyd as prior art after finding Arctic Cat failed to prove continuous diligence to antedate Boyd.
On appeal, the Federal Circuit affirmed the procedural exclusion of the transcript, affirmed that the vehicle preambles are non-limiting, reversed the PTAB’s conclusion that Boyd was prior art (finding sufficient diligence), vacated related PTAB findings that depended on Boyd for the ’188 patent, and affirmed the PTAB’s judgment as to the ’822 patent on the Svette–Matsuoka ground.

Issues

Issue	Arctic Cat (Plaintiff) Argument	GEP (Defendant) Argument	Held
Whether the PTAB abused discretion by expunging Arctic Cat’s late-filed full deposition transcript	Transcript should have been admitted; 37 C.F.R. § 42.53 requires deposition transcripts be filed and adversary may file full transcript	Submission was unauthorized and untimely; PTAB may expunge late filings under 37 C.F.R. § 42.7(a)	No abuse of discretion; PTAB permissibly expunged the late transcript given expedition interests and Arctic Cat’s failure to justify delay
Whether preamble language referring to a “personal recreational vehicle” limits claims in the ’188 and ’822 patents	Preamble limits scope; vehicle language is part of claimed invention context	Preamble is an intended-use descriptor and not limiting where claim body defines a structurally complete module	Preamble language is non-limiting for the challenged claims (claims 1 & 11 of ’188; claim 1 and dependents 2–4 of ’822) because bodies define complete inventions and vehicle reference is conventional intended use
Whether Boyd is prior art under 35 U.S.C. § 102(e) (i.e., whether Janisch antedated Boyd)	Janisch conceived before Apr. 1, 2002 and exercised reasonable, continuous diligence to reduce to practice through Oct. 29, 2002; thus Boyd is not prior art	Antarctic Cat did not show continuous diligence through the critical period; Boyd is an earlier-filed patent application and is § 102(e) prior art	Reversed PTAB on this point: substantial record evidence (tests, emails, revisions, oversight) shows reasonable diligence; Janisch antedated Boyd, so Boyd is not prior art
Remedy / effect on PTAB unpatentability rulings	Vacate rulings that rely on Boyd and remand for proceedings without Boyd as prior art	Maintain PTAB findings where Boyd not required (e.g., ’822 decision on Svette–Matsuoka)	For ’188: reverse in part and vacate PTAB decisions relying on Boyd; remand for further proceedings without Boyd. For ’822: affirmed (Svette–Matsuoka ground unaffected)
