Daniel L. Cusher

Based on the provided case list and publicly available information as of May 12, 2026, there is no verifiable record of a patent litigation practice for an attorney named Daniel L. Cusher of The Cusher Law Firm. Extensive searches of legal directories, court records, and legal news publications did not identify an attorney by this name practicing in the field of patent law. The Oklahoma-based "Cusher Law Firm" found in public records does not list patent law as a practice area.

The authoritative case list identifies Mr. Cusher as lead counsel for the plaintiff in a single matter, ABC IP LLC, et al. v. Cope. Other patent infringement cases involving plaintiff ABC IP LLC relate to mechanical patents for firearm trigger mechanisms. However, without further verifiable appearances, it is not possible to determine if this represents a typical area of focus.

Given the single, plaintiff-side appearance in the provided data, a broader assessment of Mr. Cusher’s side preference or client type cannot be made. No information regarding his professional history, including prior firms, notable trial outcomes, or experience before the Patent Trial and Appeal Board (PTAB), could be publicly verified.

No reliable sources were found to confirm bar admissions or educational background for a patent attorney named Daniel L. Cusher.
