Evelyn Li-Jin Chang

I'll research this attorney before drafting the summary.

Evelyn Li-Jin Chang — Associate, Morrison Foerster (Palo Alto)

Focus areas. Chang's public case work spans two distinct technology areas: consumer-electronics/camera technology and biopharmaceuticals. She was a team member in the ITC Section 337 investigation over 360-degree camera features — image stabilization, horizon leveling, distortion correction, and aspect-ratio conversion (Inv. No. 337-TA-1400). Earlier she worked on Morrison Foerster's trial team for Seagen in antibody-drug conjugate (ADC) patent litigation over U.S. Patent No. 10,808,039, and on related PTAB proceedings. Her firm bio describes a practice focused on patent disputes and litigation, with additional work on contract disputes over patent and technology rights for biopharmaceutical companies. Her M.S./B.S. in chemical engineering (Stanford) is consistent with the life-sciences/chemistry side of that docket; there is no indication in the available record of Wi-Fi/standards-essential patent work or mechanical-arts work.

Side preference. The tracked data shows one appearance, entirely on the defense side (defending Insta360 against GoPro). That single data point understates her range: her most prominent documented work was for plaintiffs/patent owners — Seagen as plaintiff in E.D. Tex. and as patent owner before the PTAB — so her experience is best described as mixed-side rather than a consistent defense or NPE-oriented practice. She appears in an associate/team-member role rather than as lead counsel in the matters identified.

Firm context. She has been at Morrison Foerster (now branding as "Morrison Foerster") in the Palo Alto office throughout her tracked career. No prior firm history was found in the sources reviewed. There is no indication she has been in-house.

Notable matters and outcomes.

• GoPro, Inc. v. Insta360 (Arashi Vision (U.S.) LLC) — ITC Investigation No. 337-TA-1400. The Commission's February 26, 2026 final determination cleared Insta360 on all five asserted utility patents (invalid, not infringed, or both), reversed the ALJ's infringement finding on the '052 patent, and left the asserted design patent (D'435) reaching only certain older Ace-series models, with current products outside its scope. Team led by partners Lily Li and Mark Whitaker; Chang was among the listed team members. GoPro reportedly had 60 days to appeal; no appeal was confirmed in the sources reviewed.
• Seagen Inc. v. Daiichi Sankyo Co. — E.D. Tex. jury verdict, April 8, 2022: willful infringement of the '039 patent, $41.8 million in damages plus an 8% running royalty, the full amount Seagen sought (National Law Journal Top 100 Verdicts of 2022). Chang is listed among the trial team. Important caveat: on December 2, 2025, the Federal Circuit reversed the denial of JMOL, held all asserted claims of the '039 patent invalid for lack of written description and enablement under §112(a), and vacated the infringement finding and damages award. Her participation in the appellate phase is not documented in the sources reviewed.

PTAB / IPR experience. Yes, at least at the patent-owner side: Morrison Foerster's team representing Seagen persuaded the PTAB to deny institution of Daiichi/AstraZeneca's post-grant review under the Fintiv framework (PGR2021-00030), a decision that followed a rehearing reversal — Chang was listed among counsel. The Board later issued a final written decision holding the claims unpatentable, and the Federal Circuit dismissed Seagen's appeal of that decision as moot. Separately, a Federal Circuit docket (In re Amgen Inc., No. 25-2193) lists an "Evelyn L. Chang" as retained counsel; I could not verify that this is the same attorney or what the proceeding concerned, so I would not rely on it.

Bar and education. Admitted to the State Bar of California on December 4, 2019 (No. 329053); registered to practice before the USPTO (Reg. No. 79051, per USPTO OED-derived data). J.D., Harvard Law School (digest submissions editor, Harvard Journal of Law and Technology; Cyberlaw Clinic); M.S. and B.S., chemical engineering, Stanford University.

Sourcing note: the firm bio, State Bar of California record, and Morrison Foerster case announcements are the primary sources here. Because her tracked appearance count is only one, the picture of her practice is necessarily built partly on firm press releases where she is listed as a team member rather than as counsel of record.
