Fan Zhang — Patent Litigation Summary

Specialty / focus. The tracked record places Fan ("Frances") Zhang in electronics- and software-centric patent disputes. Her one tracked litigation appearance, Mozido, Inc. v. Apple Inc., arose from a PTAB inter partes review involving mobile-payment/digital-wallet technology, and her USPTO filings of record as Ropes & Gray backup counsel appear in the LG Electronics IPR petitions IPR2023-01269 and IPR2023-01270 (Ropes & Gray, USPTO Customer No. 28120) — a wireless/consumer-electronics context. Her practice is best described as patent litigation and PTAB work for technology-sector clients rather than pharma, biotech, or mechanical arts. No published practice-area description from the firm was located, so this characterization rests on the docket record.

Side preference. The authoritative counts show 0 plaintiff-side and 1 defendant-side appearance, and the identifying matters are consistent with that: she represented Apple as appellee in the Federal Circuit and appears as petitioner's counsel in the LG Electronics IPRs. On the available record she acts for operating companies defending against patent claims and challenging patents at the Board, not for NPEs/PAEs asserting patents.

Firm context. She is at Ropes & Gray LLP, with USPTO correspondence directed to the firm's Washington, DC office (2099 Pennsylvania Avenue NW); a third-party directory also lists her at Ropes & Gray's Boston office. No prior firm history for the patent-litigation practice could be verified from reliable sources.

Notable cases / outcomes. Mozido, Inc. v. Apple Inc. is the standout tracked matter: Fan Zhang was on Apple's appellee team (Fed. Cir. Nos. 24-1741 and 24-1742, appeal from PTAB IPR2022-01149), alongside Sheppard Mullin and other Ropes & Gray counsel. The Federal Circuit affirmed under Rule 36 by per curiam judgment (Moore, C.J., Taranto and Hughes, JJ.) on December 8, 2025, a win for Apple. Her LG Electronics work is PTAB-side rather than merits-verdict work.

PTAB / IPR experience. Yes — she is a registered patent practitioner (USPTO Reg. No. 73,589) and appears in IPR proceedings, including as backup counsel on LG Electronics petitions (IPR2023-01269, IPR2023-01270) and in the Mozido IPR that reached the Federal Circuit. IPR work should be treated as a regular part of her practice.

Bar / education. Not reliably sourced. Her USPTO registration number is confirmed from filed powers of attorney, but no verified bar-admission list or law-school/undergraduate record was located — omit any specific claim here.

Disambiguation note. At least two other attorneys named "Fan Zhang" appear in public records and are not this lawyer: a cross-border commercial-litigation attorney admitted to the N.D. Cal. and Ninth Circuit in 2025 (lawyerfanzhang.com), and a former Qihoo 360 general counsel (ex-Kirkland & Ellis/Latham & Watkins). Neither is affiliated with Ropes & Gray's patent practice. Sources for the above are the Federal Circuit Rule 36 judgment and Justia/CourtListener dockets for Mozido v. Apple, PTAB powers of attorney for IPR2023-01269/-01270, and a directory listing; the firm bio page could not be retrieved.
