Wing Hay Liang

Summary — Wing Hay Liang (Wing H. Liang)

Practice focus. Wing Liang is a patent litigator whose docket is concentrated in electrical/computer technologies. Case-data aggregators attribute most of his matters to communications, software/security, and semiconductor/optics cases, and his verifiable litigation work centers on color-imaging and computer-networking patents (e.g., U.S. Patent Nos. 7,312,897 and 7,791,761). He has handled the full life cycle of district-court patent cases — discovery, Markman, jury and bench trials, and appeals — and is a co-author of Perkins Coie's Northern District of California Patent Law Blog.

Side preference and firm context. The tracked appearance data shows Liang solely on the defendant side (one pro hac vice appearance for Perkins Coie; zero plaintiff-side matters). Web-verifiable work is consistent: he has represented operating company Adobe Inc. against patent-assertion entity RAH Color Technologies LLC, both in district court and before the PTAB. He is currently Counsel at Perkins Coie LLP in Palo Alto, and data aggregators show a prior stint at Fish & Richardson. He is a member of the California and New York bars and a registered USPTO practitioner (Reg. No. 78,846).

Notable matters and PTAB/IPR experience. Liang's most prominent verified engagement is RAH Color Technologies LLC v. Adobe Inc. (N.D. Cal. 3:18-cv-03277, part of MDL No. 2874), a coordinated color-management patent campaign, which he defended alongside related IPRs — including IPR2019-00646 (U.S. Patent 7,791,761), IPR2019-00629 (U.S. Patent 7,312,897), and sibling proceedings — serving as back-up/pro hac vice counsel for petitioner Adobe. His IPR practice is substantial: PTAB filings confirm pro hac vice admissions in at least seven proceedings between 2017 and 2019 (IPR2015-01802; IPR2017-01891 through -01896; IPR2019-00627/-00628), after which he obtained full USPTO registration.
