Paul T. Ehrlich

I'll research this attorney before drafting.

Let me verify the notable outcomes and the DivX/Hulu matter.

Let me check for other notable matters and PTAB activity.

Paul T. Ehrlich — Tensegrity Law Group LLP

Focus areas. Ehrlich's tracked matters sit at two ends of the technology spectrum: video streaming and digital rights management (DivX, LLC v. Hulu, LLC, C.D. Cal.) and spatial genomics/life sciences (10x Genomics, Inc. et al. v. Vizgen, Inc., D. Del.). That range is consistent with his firm biography and third-party rankings, which describe a practice spanning biotechnology and medical devices, mobile phones and consumer electronics, computer networking, operating systems and database software, VoIP, memory manufacture and packaging, and Wi-Fi and location services. His Yale undergraduate degree is in biomedical engineering, which aligns with the biotechnology/medical-device side of the docket. Searches of public dockets show additional work beyond the two tracked matters, including DivX's ITC enforcement action against Amazon and VIZIO and Wi-Fi positioning litigation for Skyhook Wireless against Google in D. Massachusetts (Wi-Fi/location-patent summary judgment rulings), plus DNA-sequencing/spatial-biology suits for 10x Genomics and Harvard against Curio Bioscience, Scale Biosciences/Parse Biosciences, and Element Biosciences.

Side preference. Both tracked appearances are plaintiff-side (2 plaintiff, 0 defendant), and the clients are technology operating companies and patent owners/licensees — 10x Genomics, Harvard, DivX, and Skyhook — rather than NPEs or PAEs. That said, public records show he also does defensive/validity-side work, for example representing Arista Networks as petitioner in IPRs against Cisco networking patents. The fairest characterization from the available record is a patent-owner/enforcement orientation with regular defense-side representation, not a pure one-way practice.

Firm context. Ehrlich is a founding partner and Co-Managing Partner of Tensegrity Law Group LLP (Redwood Shores, CA, with a McLean, VA office), which he helped launch in 2011; Chambers lists him as head of the firm's IP department. Before founding Tensegrity he was an associate at Weil, Gotshal & Manges LLP. Tensegrity is a patent-trial boutique founded by former Weil Gotshal lawyers, described by World IP Review as strongest in patent enforcement and monetization work.

Notable matters. In 10x Genomics v. Vizgen (D. Del.), the court granted summary judgment dismissing Vizgen's antitrust counterclaims and all of Vizgen's claims against 10x in January 2025, and the case was dismissed with prejudice in February 2025 after three days of trial (reported damages sought: about $9.2 million by plaintiffs; Vizgen's counterclaim exposure was reported in the $91–374 million range). The docket lists Ehrlich among 10x/Harvard's counsel. He is also listed as counsel for DivX in the DivX v. Hulu litigation, where Hulu's IPRs largely failed to knock out the asserted claims and DivX successfully moved to lift the stay.

PTAB / IPR experience. Yes — he appears regularly in PTAB proceedings, including pro hac vice admissions in Arista Networks v. Cisco (IPR2016-00303/306/308/309), the 10x/Harvard-side proceedings against Bruker (IPR2024-00526) and in IPR2023-00955 (Parse Biosciences/USPTO docket) and IPR2024-01289. World IP Review identifies him as a team member on 10x's PTAB challenge to NanoString, which terminated in May 2025 following a global settlement.

Bar / education. Admitted in California (2003), the U.S. Courts of Appeals for the Federal Circuit and Ninth Circuit, and numerous district courts including N.D./C.D./S.D. Cal., E.D. and W.D. Tex., and W.D. Wis.; J.D., Berkeley Law (2003); B.S., Biomedical Engineering, Yale University (2000).

Caveats: the tracked-appearance list is limited to two cases and is narrower than his publicly documented docket; the Skyhook, Curio, Element Biosciences, and counsel-of-record details above come from court filings, PTAB papers, and legal-directory profiles rather than the authoritative list. Firm-profile claims such as service as trial counsel in "billion-dollar matters" are the firm's own characterization and are not independently verified here.
