Adam Powell

I'll research this attorney and verify the tracked case.

Let me dig into the tracked case and his PTAB/trial record.

Adam Powell — Patent Litigation Practice Summary

Focus areas. Adam B. Powell is a litigation partner at Knobbe Martens (San Diego office; California Bar No. 272725, USPTO Reg. No. 70,367), where he also co-chairs the firm's antitrust practice group. His practice is a mix of patent, trade secret, antitrust, copyright, and contract litigation. Firm and press descriptions place his technology experience in medical device, software, electronics, chemistry, and biotechnology matters. He has published and spoken on the patent/antitrust interface (e.g., FTC v. Endo Pharmaceuticals), prosecution laches in Google v. Sonos, and the Federal Circuit's expert-testimony ruling in Finesse Wireless v. AT&T Mobility, indicating a standards/technically complex electronics dimension to his work alongside life sciences.

Side preference. His single tracked appearance in this dataset is defense-side (Unified Patents v. Brain Corp, as counsel for Brain Corp), which skews the counts to 0 plaintiff / 1 defendant. That thin tracked record is not representative, however: public filings show Powell doing substantial patent-owner (plaintiff-side) work, most prominently on the Masimo/Cercacor side of the long-running Masimo v. Apple dispute. In practice he should be viewed as working both sides — defending operating companies against validity challenges and asserting patents for patent owners — rather than as an NPE/PAE-side prosecutor. Note the caveat that the tracked one-case sample is too small to draw a side-preference conclusion on its own.

Firm context. Powell's patent litigation career is at Knobbe, Martens, Olson & Bear, LLP, the IP boutique where the tracked appearance places him; I found no public record of prior firms relevant to this practice. He is based in the firm's San Diego office.

Notable matters. The most prominent publicly verified matter is Masimo Corp. v. Apple Inc. (C.D. Cal.), where a jury returned a $634.3 million infringement verdict against Apple in November 2025 on Masimo's pulse-oximetry/heart-monitoring patents; Powell is listed among the Knobbe team, though press accounts identify Brian Horne as lead trial counsel and Joseph Re, Stephen Jensen, and others as trial presenters, so his role was as part of a large team rather than as first chair. The same firm team secured an ITC import ban on infringing Apple Watches (2024) and a permanent injunction for Masimo. The tracked Unified Patents v. Brain Corp matter involves Unified Patents, a defensive aggregator that challenges patents via IPR; details of that specific case beyond the tracked record were not independently verifiable in my search.

PTAB / IPR experience. Powell appears in PTAB proceedings as backup counsel on the patent-owner side, including for Masimo in the Apple-filed IPRs (e.g., IPR2024-00293, IPR2024-00294). This is consistent with IPR experience but, on the public record I located, as a team member rather than as a frequent lead petitioner or lead patent-owner counsel.

Bar / education. Admitted to the State Bar of California on December 3, 2010 (license active); registered to practice before the USPTO (Reg. No. 70,367); J.D. from UC College of the Law, San Francisco (formerly UC Hastings).
