Frank Yang — patent litigation practice summary

Specialty / focus areas. The tracked record contains a single matter, IPValue Management, Inc. v. Western Digital Corporation (C.D. Cal., No. 8:25-cv-00119, filed Jan. 22, 2025). The asserted patents (originally from Cypress Semiconductor, owned by Longitude Flash Memory Solutions Ltd. and enforced by IPValue) concern 3D NAND flash memory and read on a broad range of accused devices — embedded flash, HDDs, SSDs, USB flash drives and memory cards. That places the practice in data-storage / non-volatile-memory and semiconductor technology rather than Wi-Fi standards, pharma or mechanical arts. Beyond this one case there is no reliable public record of the technology breadth of his docket, so any broader characterization would be speculation.

Side preference. The tracked data show 0 plaintiff-side and 1 defendant-side appearance, with the role listed as "senior patent counsel." That is an exclusively defensive posture, and the title is more consistent with in-house counsel than with an outside litigation firm; there is no tracked record of representing NPE/PAE plaintiffs.

Firm context. No current or prior firm is reliably verifiable from public sources. The most plausible inference from the case list is that he is (or was) in-house patent counsel at Western Digital, which is the named defendant. A USPTO-registered practitioner named Frank B. Yang (Reg. No. 65788) shows a filing history concentrated in Western Digital Technologies, Inc. and Applied Materials, Inc., which would be consistent with an in-house prosecution/litigation role in the semiconductor and storage industry — but I could not confirm that this is the same individual, and it should not be treated as verified. Searches for "Frank Yang" also surface unrelated attorneys (e.g., a junior attorney profile referencing Fenwick & West/Norton Rose Fulbright; Finnegan's Ming-Tao Yang), none of which can be attributed to this attorney.

Notable cases, PTAB and bar/education. The only tracked matter is the IPValue/Western Digital action. IPValue filed a First Amended Complaint adding SanDisk as a co-defendant in April 2025; the court docket shows Western Digital moving to dismiss and to stay in favor of a related N.D. Cal. action, so no outcome on the merits is yet reflected in the sources reviewed. There is no public evidence of IPR/PGR participation by this attorney, and no reliably sourced bar admission(s) or law-school/undergraduate education could be confirmed — those fields are therefore left blank rather than estimated.

Sourcing note: Because the profile rests on one tracked appearance and the attorney's name is common, several of the above items are inferences flagged as unverified. Confirming the current employer, bar admissions and PTAB history would require a PACER docket check and the USPTO patent-practitioner register for the specific individual.
