Guy Ruttenberg

Practice focus. Ruttenberg is a patent litigator whose work centers on software and computer-networking disputes — including the tracked SportsCastr Inc. v. Genius Sports Ltd. case (E.D. Tex., filed Oct. 2023), which involves SportsCastr's live sports-video streaming and synchronized data-feed patents — with historical depth in wireless/telecom (Wi-Fi/WiMAX, satellite, and wireless communications standards), medical devices/life sciences, and chemical/mechanical matters. Chambers USA's spotlight profile of his firm describes it as handling complex patent disputes in the technology, communications, and life sciences sectors for clients in Asia and Israel. All two tracked appearances are defendant-side (0 plaintiff), representing accused operating companies — he is listed as trial counsel for defendant Genius Sports in SportsCastr — though his published biography also shows earlier assertion work for clients such as Abbott and j2 Global.

Firm context. Ruttenberg is the founder and principal of Ruttenberg IP Law, APC, a Century City, Los Angeles IP litigation boutique he established in 2012 after 12 years at Kirkland & Ellis LLP (Oct. 2000–Oct. 2012), including seven as a partner in Los Angeles focused on IP litigation and Pacific Rim matters. He also spent stints as a visiting attorney at Broad & Bright in Beijing and Nagashima Ohno & Tsunematsu in Tokyo, and clerked for the Alaska Supreme Court. Note a data nuance: the case-tracking record attributes both tracked appearances to Kirkland & Ellis, whereas public sources place him at his own firm since 2012; public docket entries I reviewed for SportsCastr primarily list other Kirkland attorneys, so I could not independently verify how that appearance is attributed.

Notable cases. His firm bio (self-reported) highlights a fully favorable defense verdict for Honeywell invalidating Solvay's foam-blowing-agent patent on three independent grounds (Solvay v. Honeywell); a jury defense verdict for Limelight in CDN patent litigation that survived post-trial motions and Federal Circuit review (Level 3 Communications v. Limelight); summary judgment of invalidity for DIRECTV affirmed on appeal (Northpoint Technology v. DIRECTV); representation of Intel against Wi-LAN in Wi-Fi/WiMAX suits; and defense of Samsung against Ericsson across parallel ITC Section 337 investigations and E.D. Tex. actions involving roughly 60 wireless patents. The tracked SportsCastr litigation runs parallel to six Genius Sports IPR petitions against SportsCastr's patents.

PTAB/IPR and credentials. His PTAB exposure is real but modest: a 2023 Board order in IPR2019-01094 (AMP Plus, Inc. d/b/a Elco Lighting v. DMF, Inc.) substituted Ruttenberg IP Law's Bruce Kuyper as lead and Ruttenberg as backup counsel — he is not, on this record, a high-volume IPR lead. Bar/education: California Bar (2000); J.D., Harvard Law School (1999, cum laude); B.A., UCLA (1996, summa cum laude); admitted to the Federal Circuit and Ninth Circuit.
