Rose S. Lee

Specialty / Focus Areas. Rose S. Lee is a registered patent attorney whose practice centers on complex IP litigation — patent, copyright, and trade secret matters — across high-technology sectors. Per her Morrison Foerster bio, her matters have spanned computer software, video encoding, semiconductors, underwater imaging, electrostatic digital printing, and medical devices, with experience in U.S. district courts and Section 337 proceedings at the ITC. Her tracked work in Parus Holdings, Inc. v. Apple Inc. (W.D. Tex.) involved voice-recognition/browser technology patents.

Side Preference / Firm Context. Both tracked appearances are on the defense side (2 of 2), representing operating companies against patent assertions — she appeared for Apple in the Parus matter as lead/defense counsel while at O'Melveny & Myers. Her broader record is consistent: representing Palo Alto Networks, Raymarine, International Laser Group, and C. R. Bard as defendants/respondents, rather than prosecuting claims for NPEs/PAEs. She is currently based in Morrison Foerster's Los Angeles office (she joined MoFo at the start of her career as a litigation associate, later spending time at O'Melveny per the tracked case data). She previously externed for Judge R. Gary Klausner, C.D. Cal.

Notable Cases / Outcomes. The tracked cases are the Parus Holdings v. Apple voice-browser patent suits. From web sources: she helped secure dismissal with prejudice of a copyright/trade secret suit against Palo Alto Networks (C.D. Cal.); represented International Laser Group against Canon in ITC 337-TA-918, which settled favorably allowing continued U.S. sales of remanufactured toner cartridges; represented Raymarine in ITC 337-TA-898 (underwater imaging); and has represented C. R. Bard in power-injectable port patent litigation in Delaware. She was also admitted pro hac vice in The Intercept Media v. OpenAI (S.D.N.Y., 2024).

PTAB / IPR Experience. Her bio states she represents clients in adversarial PTAB proceedings, and her litigation has run parallel to IPR challenges (e.g., the related Apple v. Parus Holdings IPR2020-00686). However, I could not verify specific IPR appearances attributable to her by name, so her PTAB workload should be characterized as reported by her firm rather than confirmed from dockets.

Bar / Education. California bar and USPTO registration; J.D. 2013 (US News profile). Her undergraduate degree was in chemical engineering per a Morrison Foerster firm profile; law school is not reliably sourced and is omitted.
