Ari B. Rafilson

I'll research Ari B. Rafilson's professional background before drafting.

Ari B. Rafilson — patent litigation summary

Focus and technology areas. Rafilson's practice centers on patent litigation and related licensing, with a technical emphasis on software, networking, and electronics rather than life sciences. Firm bios describe work spanning video streaming content delivery, internet search methods, object-oriented/object-relational software, integrated circuits, field programmable gate arrays, LED displays, motion-sensing systems, and magnetic resonance imaging. He is a registered patent practitioner (USPTO Reg. No. 58,693), and his bios note pre-law experience in computer science as an instructor, systems integrator, consultant, and project manager — consistent with the software/streaming subject matter of the tracked cases.

Side preference. The tracked docket is weighted to the plaintiff/patent-owner side (6 plaintiff to 2 defendant). The public record matches: his earliest appearances were for NPE-style plaintiffs (PA Advisors/nXn Tech and Bright Response matters in E.D. Tex., 2009; Reconstructor Holdings in N.D. Cal., 2016), and later work has been for patent owners such as VideoShare in the Western District of Texas and for university/licensing patent owners in PTAB proceedings. He is not, however, a one-sided practitioner — his own bios state that he represents "plaintiffs and defendants" including universities, research institutes, individual inventors, software companies, and patent-licensing firms, and that prior licensing and litigation efforts produced several seven- and eight-figure settlements for patent holders.

Firm context. The tracked data lists Cherry Johnson Siegmund James, PLLC (Waco, Texas), where he is identified as a partner and entered an appearance as additional counsel for VideoShare, LLC as recently as June 2024. Prior Dallas-centric stops documented in press and court filings include McKool Smith, which announced him as a principal in its Dallas office in August 2022; Shore Chan DePumpo / Shore Chan LLP (appearances c. 2016–2021, and his email appears on Shore Chan correspondence into 2022); his own Rafilson Law Firm, PLLC; and Sidley Austin LLP, where he handled IP litigation and patent prosecution. Caveat: the tracked list also attributes three SportsCastr matters to King & Spalding (counsel of record / district court counsel). I could not independently verify a King & Spalding affiliation from firm press releases, bar listings, or the firm's own site, and King & Spalding's public PTAB filings in the SportsCastr IPRs name other attorneys (e.g., B. Eutermoser) as patent-owner counsel. That attribution should be confirmed before it is relied on.

Notable matters and PTAB/IPR experience. His firm bios credit him as co-lead counsel in a trial that produced a $25.9 million jury verdict against Google; the underlying case is not named in the bio, though his docket presence in VideoShare LLC v. Google LLC / YouTube (W.D. Tex. No. 6:19-cv-00663) and VideoShare LLC v. Meta Platforms (W.D. Tex. No. 6:21-cv-00254) suggests the VideoShare litigation, and the attribution is worth verifying. The most prominent tracked matters are the SportsCastr Inc. (d/b/a PANDA Interactive) streaming disputes against Genius Sports (E.D. Tex. No. 2:23-cv-00471) and Sportradar Group (No. 2:23-cv-00472), which generated a parallel IPR family (IPR2024-01305, -01307 through -01311; IPR2025-00251 and -00252; IPR2025-00273) in which SportsCastr is patent owner — institution was granted on several patents. He also appears as IPR patent-owner counsel for STC.UNM (IPR2020-00009), UNM Rainforest Innovations (IPR2020-01578), and CyWee Group (IPR2019-00143), so PTAB work is a recurring part of his practice rather than occasional. A Federal Circuit appeal, No. 26-1809, is tracked with him as attorney of record; no public outcome is available.

Bar and education. Licensed in Texas (2007); USPTO Reg. No. 58,693; admitted to the U.S. Court of Appeals for the Federal Circuit and the W.D., E.D., and N.D. of Texas. J.D., cum laude, SMU Dedman School of Law (2007); B.S. in Computer Information Systems, magna cum laude, Bradley University (1988).
