Rudolph "Rudy" Fink, IV

I'll research this attorney before writing the summary.

Let me dig deeper into his background, firm profile, and PTAB experience.

Rudolph "Rudy" Fink IV — Patent Litigation Practice Summary

Specialty / focus areas. Fink's verified docket work is concentrated in electronics and computer-technology patent litigation in the Eastern District of Texas (Marshall), with recurring subject matter in communications/broadband (TQ Delta's DSL and home-networking patent families), computer architecture and software, semiconductors, and data-center cooling hardware (the Vertiv/Valtrus dispute over Liebert cooling and iCOM control systems). A court-record practice summary also reflects work in software/security and transportation/telecom matters. He appears to function heavily as Texas local counsel supporting out-of-state lead counsel (e.g., Oppenheim + Zebrak, Brown Rudnick, and other firms in the filings reviewed), handling E.D. Tex. procedural and discovery workstreams.

Side preference. His tracked record shows a single plaintiff-side appearance, but public filings show a consistent pattern of representing patent holders and plaintiffs rather than defendants: he appeared for plaintiff TQ Delta, LLC in TQ Delta, LLC v. CommScope Holding Company (E.D. Tex. 2:21-cv-00310, counsel of record and declarant on multiple filings), for plaintiff Blitzsafe Texas, LLC while at McKool Smith (E.D. Tex. 2:15-cv-01274/1277, auto-infotainment patents), and for plaintiff Flow Motion Research & Development Ltd. in a 2026 E.D. Tex. suit against Peloton. In the tracked Vertiv v. Valtrus matter he appears for plaintiff Vertiv, which is an operating company suing a patent owner for declaratory judgment of non-infringement — so his side profile is best described as plaintiff-side patent work spanning both NPE/patent-holder plaintiffs and operating-company declaratory-judgment plaintiffs, not defense-side work.

Firm context. He is currently a partner at The Davis Firm, P.C. in Longview, Texas, where he practices alongside William E. ("Bill") Davis, III. Court filings and conference programs confirm he was previously an associate at McKool Smith in Dallas, where his patent litigation work included the Blitzsafe matters. (Some aggregator sources also list earlier technical-specialist/technical-advisor roles and federal clerkships, but those are not corroborated by a reliable legal source and are noted here only as unverified.)

Notable cases and outcomes. The most prominent tracked matter is Vertiv Corporation v. Valtrus Innovations Ltd. (N.D. Tex. 3:24-cv-01152, later consolidated in E.D. Tex.), a declaratory-judgment and customer-indemnification dispute over data-center cooling patents in which Vertiv also filed an IPR against the '287 patent and the parties litigated extensive summary-judgment and Daubert motions; the consolidated E.D. Tex. case is set for a 2028 trial. His highest-volume public engagement is the TQ Delta/CommScope-Nokia-ARRIS litigation, where a related TQ Delta jury trial produced a headline multi-million-dollar verdict in the DSL patent family litigation, though no judgment attributable specifically to Fink's individual role is documented. I did not find a sourced, Fink-specific verdict, Federal Circuit argument, or settlement figure to attribute to him personally.

PTAB / IPR experience. PTAB records show his firm and name in connection with IPR petitions (e.g., USPTO P-TACTS petition filings naming him as attorney to be noticed), and the Vertiv/Valtrus matter involved an IPR petition against the '287 patent. His PTAB involvement appears occasional rather than a dedicated practice — no substantial standalone IPR/PGR docket is verifiable from available sources.

Bar / education. Member of the State Bar of Texas, Texas Bar No. 24082997; admitted to practice in the Eastern District of Texas. Reliable legal sources confirming his law school and undergraduate education were not located, so no education line is included.
