Jason Rawnsley

I'll research this attorney before drafting.

Let me verify the tracked case and PTAB activity.

Jason J. Rawnsley — Richards, Layton & Finger (Wilmington, DE)

Focus areas. Rawnsley's practice centers on IP and complex commercial litigation in Delaware's federal and state courts (D. Del. is the venue for most of it) plus arbitration. His patent docket skews toward electronics and life sciences: semiconductor components and medical-device electronics (Greatbatch v. AVX), digital signal processors (FastVDO v. Texas Instruments), genomics/spatial-biology tools (10x Genomics matters), pharmaceuticals (Millennium v. Actavis), and streaming/media-delivery technology (the Adeia matter). Firm and directory descriptions characterize his sectors as telecommunications, bioscience, and entertainment, with additional experience in trademark, copyright, trade-secret, non-compete, and domain-name disputes. Chambers USA ranks him Band 4 for Intellectual Property in Delaware; he also appears in IAM Patent 1000 and Best Lawyers (Commercial Litigation; Litigation–IP).

Side preference. Predominantly defense-side. The tracked record shows 0 plaintiff and 1 defendant appearance, and much of his documented work is defending operating companies against infringement claims (AVX, Texas Instruments, NanoString's adversary posture aside). That said, he is not exclusively a defense lawyer — the Richards Layton team represented 10x Genomics and Prognosys as patentees pursuing infringement claims, so he has meaningful plaintiff-side/patent-enforcement experience as well.

Firm context. Rawnsley is a Director at Richards, Layton & Finger, P.A., Delaware's largest firm, where he has practiced since at least 2009 (admitted to the Delaware bar in 2009) and was elevated to director in January 2021. He appears as Delaware local counsel alongside out-of-state lead firms, a common Delaware role. No prior firm history surfaced in the sources reviewed; there is no indication he has been in-house.

Notable cases. The most prominent tracked matter is Adeia Media Holdings LLC et al. v. BAMTech, LLC et al. (D. Del. 1:24-cv-01231), in which Adeia (a patent-assertion entity, formerly TiVo/Rovi) asserted six streaming and interactive-program-guide patents against Disney entities including BAMTech, Hulu, and ESPN. Rawnsley served as Delaware counsel for the defendants; the case was dismissed with prejudice on December 29, 2025 following settlement, with no merits ruling. Also notable is 10x Genomics v. NanoString Technologies (D. Del. 1:21-cv-00653), where Richards Layton was co-counsel with Tensegrity Law Group and the jury returned a November 17, 2023 verdict for 10x — willful infringement of seven spatial-biology patents and more than $31 million in damages, followed by post-trial proceedings against successor Bruker Spatial Biology. He also worked on 10x Genomics v. Celsee, 10x Genomics & Harvard v. Vizgen, and FriendFinder Networks v. Penthouse Global Media (domain-name recovery).

PTAB / IPR. IPR activity appears in his cases but I could not reliably confirm him as lead PTAB counsel from public sources. In the 10x/Bio-Rad-Celsee dispute he was counsel on 10x's motion to stay the district court case pending institution of four IPRs; in the Adeia matter, the Disney defendants filed six IPR petitions in late 2025 and moved to dismiss them pre-institution after the settlement. Treat his PTAB work as adjacent litigation support rather than a documented standalone IPR practice.

Bar / education. Admitted in Delaware (2009). J.D., magna cum laude, Notre Dame Law School (2009), articles editor of the Notre Dame Law Review; M.A., Bryn Mawr Graduate School of Arts and Sciences (2005); B.A. in Classics, Villanova University (2003), Phi Beta Kappa.

Sourcing note: background drawn from the Richards Layton firm profile and bios, Chambers USA, IAM Patent 1000, and Delaware federal dockets. Several third-party attorney-analytics aggregators were excluded as unreliable. Confirm IPR participation directly with the attorney if it matters to the engagement.
