Adam P. Daniels

I'll research this attorney's background and practice.

Let me gather more detail on his cases and practice.

Let me check outcomes and the PTAB footprint.

Adam P. Daniels — Polsinelli (Los Angeles) — patent litigator with an electrical engineering background; his tracked docket is concentrated in consumer-electronics input/interface technology and, more recently, AI/machine-learning software.

Specialty / focus. Daniels is a member of Polsinelli's Intellectual Property group and describes his practice as spanning patent and trademark litigation, patent prosecution, post-grant proceedings at the USPTO, licensing and investment funding. His technical profile is electrical/computer engineering (BS ECE, Worcester Polytechnic Institute) and he worked as an engineer at Sikorsky Aircraft before law school, which aligns with his case mix: optical/photodetector-based touch and input-sensing systems for smartphones and consumer devices (Power2B), and AI inference software — transformer models, dynamic batching, cache memory (FriendliAI v. Hugging Face). He also handles trademark and copyright work and licensing; his firm profiles note clients ranging from start-ups to large tech and financial institutions.

Side preference. Both sides, with a measurable tilt toward patent-owner/plaintiff work. Of his three tracked appearances, two are plaintiff side and one is defendant side — and both plaintiff entries arise from his lead role representing Power2B, Inc., a Los Angeles start-up patent owner, in its assertion campaign against Samsung. The "defendant" entry corresponds to the parallel PTAB proceedings, where Polsinelli represented Power2B as patent owner (respondent), so his Power2B work as a whole is patent-owner-side. He also does conventional operating-company defense: he was admitted pro hac vice in the District of Delaware to represent defendant Hugging Face, Inc. in FriendliAI Inc. v. Hugging Face, Inc., No. 1:23-cv-00816-MN (D. Del.), which was terminated by a stipulated dismissal with prejudice (D.I. 136). A third tracked plaintiff-side matter is not identified in the data I have.

Notable cases / outcomes. Power2B, Inc. v. Samsung Electronics Co. et al. is his most prominent matter. He led Polsinelli's assertion of five Power2B patents ('570, '364, '994, '369, '070) in the Western District of Texas before Judge Albright (6:20-cv-01183) and the Eastern District of Texas before Judge Gilstrap (2:21-cv-00348), litigating in parallel with a substantial IPR campaign Samsung brought against the same patents (motion to disqualify Polsinelli was filed by Samsung in the district case in August 2021). He appeared as counsel for Power2B on appeal in three Federal Circuit appeals (Nos. 23-1629, 23-2184, 24-1399); the 2025 decisions were mixed — panels affirmed the Board's obviousness findings on most challenged claims but reversed as to certain claims, including claim 20 of the '364 patent, over a dissent — and Power2B sought panel or en banc rehearing. I did not verify a final judgment, trial verdict, or settlement in the underlying Texas district court cases; treat their status as unresolved.

PTAB / IPR experience. Yes — post-grant work is a documented part of his practice, not occasional. He was counsel for Patent Owner Power2B in Samsung's IPRs, including IPR2021-01220 ('675), IPR2021-01257, and the consolidated IPR2022-00315 ('070) and IPR2022-00325 ('369), which proceeded to a combined oral hearing and resulted in the Federal Circuit appeals above. Note: Hugging Face filed IPR2024-01234 against FriendliAI's '775 patent while the Delaware case was pending; my sources confirm Fenwick & West represented the patent owner but do not confirm whether Daniels or Polsinelli appeared for petitioner Hugging Face in that IPR.

Firm, bar, education. He is a Principal in Polsinelli's Los Angeles office; an earlier profile lists prior experience at Edwards Wildman Palmer LLP (a lower-confidence source, since that firm combined into Locke Lord in 2015). Bar: first admitted 2010, California since 2014, also admitted in Connecticut, Massachusetts, and New York, and registered before the USPTO (D. Mass. and S.D.N.Y. admissions per directory listings). Education: J.D., University of Connecticut School of Law (2010), with certificates of study in intellectual property and taxation; B.S. in electrical engineering and computer engineering, Worcester Polytechnic Institute.
