Sarah Casey

I'll research this attorney, carefully disambiguating given the common name.

Confirmed: Sarah Ann Casey moved from Goodwin Procter to Maschoff Brennan. Let me verify her cases and PTAB experience.

Let me verify the Nike v. New Balance matter and her broader case history.

Sarah Ann Casey — patent litigation summary

Specialty / focus. Casey is an IP litigator whose practice spans patent and trade-secret disputes over a broad range of technologies. Her Maschoff Brennan bio lists remote controls, IoT/connected-home and home-security systems, antennas, printing mechanisms, cybersecurity packet encryption, vehicle telematics, DSL, electronic messaging, EV batteries, pathogen-testing methods, optical lenses, and "knit running shoes" — the last matching the footwear-knitting subject matter of the Nike–New Balance dispute. Her earlier Goodwin Procter profile (IAM, California bar listing) describes general IP litigation with some experience assisting German Regional Court patent cases. Her educational background is in environmental science rather than engineering, so her patent work appears to be litigation-focused rather than prosecution-heavy.

Side preference. The tracked record shows a genuinely two-sided practice (1 plaintiff, 1 defendant), but weighted toward defending operating companies. In the Nike matter she was on the defense side for New Balance against Nike, and her Goodwin-era docket also included defendant work for Ziff Davis and Recreational Equipment against patent-assertion plaintiffs (Peter Pedersen v. Ziff Davis; RECOG IP LLC v. Recreational Equipment, W.D. Tex.). Her plaintiff-side appearance is Vivint's declaratory-judgment action against SB IP Holdings — which is the mirror image of an operating-company defense: Vivint was the accused party in the broader SB IP/SkyBell campaign and preemptively sued for non-infringement. In other words, both tracked appearances put her on the operating-company side of the "v." — she does not appear as NPE/PAE counsel.

Firm context. Casey is currently an associate at Maschoff Brennan (Maschoff Brennan Gilmore & Israelsen; Orange County/Salt Lake City-based IP boutique) after earlier serving as an IP litigation associate at Goodwin Procter in Los Angeles. Her public bios are consistent across both firms, indicating a straightforward associate-level move between private-practice IP litigation groups rather than an in-house role.

Notable matters. The most prominent tracked matter is the Vivint / SB IP Holdings (SkyBell) smart-doorbell and video-monitoring litigation — a multi-patent E.D. Tex. dispute in which a jury found Vivint willfully infringed two SB IP patents and awarded roughly $45.4M (later not enhanced), and which was accompanied by a large parallel IPR campaign. Casey's tracked role sits in the declaratory-judgment/non-infringement action (Vivint Inc. v. SB IP Holdings, transferred from C.D. Cal. to E.D. Tex.). The Nike v. New Balance matter concerned Nike's knit-footwear patents; note that I could not verify a specific outcome for that case from the sources available, so any result should be confirmed against the docket.

PTAB / IPR. I found no PTAB filing naming Casey personally. The IPRs tied to the Vivint–SB IP dispute were filed by Foley & Lardner for Vivint, with other Maschoff Brennan attorneys (e.g., R. Parrish Freeman, Eric Maschoff) handling related Patent Owner matters. Her verifiable track record is therefore district-court litigation, not a documented IPR/PGR practice.

Bar / education. Admitted in California (bar no. 334839, 2021), New York, and D.C.; J.D., UC College of the Law, San Francisco (Hastings), 2020; B.S. Environmental Science, UCLA, 2017. (Sources: Maschoff Brennan and Goodwin Procter/IAM bios, California State Bar listing.)
