Matthew J. Berkowitz

I'll research this attorney before drafting.

Let me verify a few more specifics.

A couple more checks on his PTAB work and prior firm matters.

Matthew J. Berkowitz — Reichman Jorgensen Lehman & Feldberg LLP (Redwood Shores, CA)

Focus areas. Berkowitz is a patent litigator whose published practice description covers consumer electronics, memory systems, automotive systems, and software and networking technologies, with additional ITC Section 337 experience. Recent matters cluster around data center/cooling hardware, cloud and distributed storage, and Wi-Fi/IEEE 802.11 standard-related patents. His B.S. in industrial engineering (Penn State) underpins the mechanical/hardware-heavy docket, and he is Chambers-ranked in California for patent litigation.

Side preference. The structured case list shows a single tracked appearance, on the plaintiff side as lead counsel. That undercounts a practice that runs in both directions: at RJLF he has represented patent owners/asserters including Valtrus Innovations and Malikie Innovations/Key Patent Innovations (BlackBerry-derived Wi-Fi portfolio), while separately serving as lead counsel for Dawgs Footwear in its long-running defense against Crocs and as lead petitioner counsel in IPR proceedings. In short, he is not a single-side specialist — his recent book of business leans toward patent-owner enforcement, but he also defends and challenges patents.

Firm and notable matters. He joined RJLF in April 2023 from Shearman & Sterling, where he launched and built the firm's IP litigation practice; he moved with a four-lawyer team including partner Patrick Colsher. Notable verifiable results: in Crocs, Inc. v. Effervescent, Inc., No. 2022-2160 (Fed. Cir. Oct. 2024), he was RJLF's lead counsel for Dawgs Footwear in a Federal Circuit reversal that revived Lanham Act false-advertising claims over Crocs' "patented" Croslite marketing, remanding to the District of Colorado. The tracked matter, Valtrus Innovations Ltd. v. Dawn Acquisitions LLC d/b/a Evoque Data Center Solutions, No. 2:24-cv-00142 (E.D. Tex.), involves data center atmospheric-control and cooling patents. Note that Valtrus's standing to sue under 35 U.S.C. § 281 was contested in a parallel Valtrus action, where the court found Valtrus had transferred substantial rights to Key Patent Innovations — a point worth checking in the Evoque case. He also appears as counsel for Malikie in its Wi-Fi assertion campaign (including the Malikie v. Core Scientific case in E.D. Tex. and a Malikie v. Toast matter that was dismissed with prejudice in September 2025).

PTAB/IPR and credentials. Berkowitz is a registered practitioner (Reg. No. 57,215) and is active before the PTAB — he served as lead counsel for a petitioner in IPR2023-00867 and appears as backup counsel for Malikie patent owner in IPR2026-00120; five Nintendo IPRs against Malikie patents were terminated on settlement in December 2025. His RJLF bio states he has been lead counsel in more than 20 district court and post-grant proceedings and has argued multiple appeals before the Federal Circuit. Education: J.D., Temple University (cum laude, ~2005) and B.S., Industrial Engineering, Pennsylvania State University. Bar admissions: California, New York, the USPTO, the Federal Circuit and Ninth Circuit, and several federal district courts.

Caveat: the case list supplied covers only one tracked appearance, so the additional matters above are drawn from firm announcements, PTAB filings, and court dockets rather than the tracked dataset; public docket entries are the most reliable confirmation of his role in each.
