Wing H. Liang

I'll research this attorney's background before writing the summary.

Let me look into his current firm and education.

Let me verify his post-Perkins Coie role and the Flexiworld case details.

Professional Summary — Wing H. Liang

Specialty / focus areas. Liang's practice centers on patent litigation and counseling in electrical engineering, computer hardware and software, and mechanical engineering, with additional experience in pharmaceutical litigation and trademark/trade-dress matters and some patent prosecution (software, hardware, business methods, and mechanical devices). His tracked case list is consistent with that technical profile: all four recorded appearances are in the Flexiworld Technologies wireless-printing disputes against Amazon.com (Wi-Fi/Bluetooth wireless data transfer and printing technology) — i.e., electronics and software rather than life sciences. Web-searchable PTAB filings also show him working on wireless device monitoring/tracking patents (the M2M Solutions v. Amazon matters) and an Adobe Systems case involving a graphics/software patent, reinforcing a software- and electronics-heavy docket.

Side preference. On the tracked record he is exclusively a defense-side attorney representing operating companies: 0 plaintiff-side vs. 4 defendant-side appearances, all on behalf of Amazon.com as defendant/petitioner. That matches his PTAB work, where he served as backup counsel for Amazon as petitioner challenging NPE/PAE-owned patents. His archived Perkins Coie bio does list at least one plaintiff-side representation (speaker assemblies), and his practice description referenced managing both "offensive and defensive" patent matters, so he should not be characterized as a pure defense specialist — but publicly verifiable appearances skew heavily defensive.

Firm context. Liang spent the bulk of his career at Perkins Coie LLP (Palo Alto), where he was counsel in the Intellectual Property practice; PTAB filings from the 2014–2020 period list him at Perkins Coie's 3150 Porter Drive, Palo Alto office. Before that he was an associate at Fish & Richardson P.C. (2006–2011; summer associate 2005). A secondary directory site lists a "Wing Liang" as a lawyer at RPX Corporation in San Francisco, and a Feb. 11, 2021 PTAB motion to withdraw counsel states he "is no longer associated with the law firm Perkins Coie LLP." I could not confirm from a reliable source that the RPX listing refers to this same attorney, so his current employer should be treated as unverified; if the RPX identification is correct, it would place him in-house at a patent risk-management/defensive-aggregation company rather than private practice.

PTAB / IPR experience. This is a notable strength. His sworn PTAB affidavits show repeated pro hac vice admissions in inter partes reviews, including IPR2014-00153/00154, IPR2015-01802, IPR2017-01891 through 01896, IPR2019-00627/0628/0629/0646, and the Amazon v. M2M Solutions proceedings IPR2019-01204 and IPR2019-01205. He was subsequently admitted to practice before the USPTO (Registration No. 78,846), after which he served as backup counsel for Amazon without needing pro hac vice status. He states experience with IPR, CBM, reexamination, and reissue work. Note that a 2020 Federal Circuit Rule 36 affirmance of related prior IPR final written decisions is referenced in those proceedings, but it is a one-word per curiam affirmance and does not constitute a substantive win attributable to him.

Bar / education. Member of the California and New York state bars; Benjamin N. Cardozo School of Law, J.D. 2006 (Senior Articles Editor, Law Review); Binghamton University (SUNY), B.S. Electrical Engineering, 2003.

Caveats: the tracked case list contains duplicate/imperfectly labeled entries for the same Flexiworld–Amazon dispute, so the "four appearances" do not necessarily reflect four distinct matters. No verified verdicts, settlements, or Federal Circuit outcomes attributable to Liang individually were located.
