William E. "Bo" Davis III

Practice focus. William E. "Bo" Davis III is an East Texas–based patent and IP litigator whose practice centers on federal court patent, copyright, and commercial litigation, with a particular emphasis on the Eastern District of Texas. His firm bio describes experience spanning "pharmaceuticals to semiconductors," and his docket reflects that breadth: the Implicit, LLC matters involved data demultiplexing/network communications patents asserted against audio-networking and network-security companies (Sonos, D&M Holdings, McAfee, Sophos, Huawei, Juniper), while the tracked Valtrus matters involve patent assertions against an IT infrastructure services provider. He is known primarily as regional/local counsel in Texas patent venues rather than as a technology-specific specialist.

Side of the docket. His two tracked appearances are split one plaintiff / one defendant, and both are as local counsel — he represented NTT Data Services as a defendant in Valtrus Innovations Ltd. v. NTT Data Services, LLC, and represented Vertiv Corporation as plaintiff in its declaratory judgment action Vertiv Corporation v. Valtrus Innovations Limited (E.D. Tex.), a mirror-image dispute against the same patent-holder group. Beyond the tracked list, public records show substantial plaintiff-side work for the licensing entity Implicit, LLC, where he acted as lead district-court counsel rather than merely local counsel. The overall picture is a genuinely two-sided practice, with a heavier concentration on representing patent owners/asserters plus defense-side work for operating companies.

Firm and background. Davis founded The Davis Firm, P.C. (Longview, Texas) in 2008, described by the firm as bringing "big law" patent litigation capability to a local practice; he is a partner there. Education: J.D., Baylor University School of Law (2004); B.A., Rhodes College, cum laude (2000). Bar admissions: Texas (2004) and Colorado (2005), plus the Eastern, Northern, and Western Districts of Texas, the Fifth Circuit, and the Federal Circuit (all 2004). He has been listed in Best Lawyers in America since 2019 for IP litigation and patent law. He is not shown in the PTAB record as a USPTO-registered practitioner.

Notable matters and PTAB work. The most substantial verified matters are the Implicit, LLC patent campaigns. He appeared for patent owner Implicit in Sonos, Inc. v. Implicit, LLC, IPR2018-00766 and -00767, and in Juniper Networks, Inc. v. Implicit, LLC, IPR2020-00585 — in each instance admitted pro hac vice as back-up counsel behind a registered practitioner, and he argued discovery issues at a consolidated PTAB telephonic hearing. The Sonos IPRs produced final written decisions invalidating the challenged claims; the resulting Federal Circuit appeal (Implicit, LLC v. Sonos, Inc., Nos. 20-1173/-1174), which the firm noticed, was vacated and remanded in light of Arthrex and later affirmed on forfeiture grounds in the March 2026 decision — an adverse outcome for his client. On the Valtrus side, the Vertiv declaratory judgment action shows a stipulated dismissal of two patents ('284 and '683) from the complaint. He is an occasional, not a regular, PTAB practitioner, and I found no verified jury verdict or other reported trial win attributable to him.
