General Motors

I'll verify what's actually behind this entry before writing, since the entity named is an automaker rather than a law firm.

Initial results confirm my concern. Let me try to verify the specific tracked case and the named attorney.

Important framing correction: the entity in the authoritative record is not a law firm. General Motors (General Motors LLC, together with patent-holding subsidiary GM Global Technology Operations LLC) is a publicly traded automaker headquartered in Detroit, Michigan. It is an operating company with an in-house legal and IP department, so the usual law-firm metrics — office footprint, AmLaw/Chambers firm ranking, partner roster, billable IP litigation practice — do not apply. There is no sourced basis for a "firm size" indicator; GM's IP work is handled by salaried in-house counsel supported by outside counsel retained case by case.

IP profile and side preference — as reflected in the tracked data. The tracked record contains exactly one appearance, and it is on the defendant side, in an in-house capacity. That is the classic operating-company posture: absorbing patent assertions rather than prosecuting them for a contingency fee, and using in-house counsel as counsel of record. With a single data point, however, this should not be read as a statistical preference — it is simply the one matter captured. GM's far more visible patent activity in public dockets runs the opposite direction: it is an active plaintiff enforcing its own design and utility patents.

Notable tracked case. The single entry is DataServe Technologies LLC et al. v. General Motors LLC, with GM as defendant and David S. Willoughby listed as in-house counsel. I was unable to independently verify this matter through public web searches; docket databases may not surface it, and the "et al." plaintiff group suggests a multi-defendant assertion, but I cannot confirm the court, filing date, patents-in-suit, or disposition. Treat the case name and counsel attribution as drawn from the structured record only.

Verified public patent litigation activity (as plaintiff). GM's documented enforcement profile centers on automotive design patents against aftermarket and collision-repair parts suppliers. In the first week of February 2026, GM filed a coordinated set of complaints in the Northern District of Illinois, District of Delaware, and Eastern District of Michigan, plus an ITC Section 337 action (In re Certain Vehicle Parts, Components Thereof, and Vehicles Containing Same, 337-TA-3884), naming LKQ Corporation, Mitchell International, Best Value Auto Body Supply, Quality Collision Parts, and others. GM is also the patent owner in the long-running LKQ Corp. v. GM Global Technology Operations LLC dispute, which produced an en banc Federal Circuit decision on the obviousness standard for design patents — the "landmark Federal Circuit design patent case" referenced in the bio of GM senior IP counsel Angela Caligiuri. Technology areas in that docket are mechanical/ornamental automotive components (bumpers, fenders, hoods, fascias, headlamps) rather than Wi-Fi, semiconductors, or pharma.

PTAB / IPR and personnel. There is a clear but modest public signal of PTAB involvement: GM's in-house IP leadership describes handling "related PTAB" proceedings alongside district court and ITC matters in the design-patent campaign. I found no public report supporting a specific IPR/PGR filing volume, so no scale figure should be asserted. Verified in-house IP names include Angela Caligiuri (Senior Counsel, IP — trademarks, design patents, brand protection, Detroit) and the record's David S. Willoughby. Note that several former GM IP lawyers have since moved to private practice — David P. Hudyma Jr. and Karl F. Barr (both now at Cantor Colburn) — which can create attribution confusion when a matter is tagged "in-house."

Bottom line: this entry describes an in-house legal department of a major automaker as a defendant in one tracked patent suit, not a law firm's patent litigation practice. Any "practice summary" in the conventional sense would need a different entity as the subject.
