Patent Litigation Consulting

Patent Litigation Consulting LLC (PLC) is a specialized legal consulting firm founded by Paul J. Hayes, based in Andover, Massachusetts. Operating as a boutique entity rather than a large, full-service firm, PLC primarily provides strategic advice to companies involved in patent litigation. No specific AmLaw or Chambers rankings were found for the firm, consistent with its focused consulting model.

The firm's expertise in IP litigation centers on high-stakes patent infringement disputes, drawing heavily on Paul J. Hayes's extensive experience. PLC offers guidance in areas such as pretrial and trial strategy, expert witness evaluation, and settlement negotiations. The firm's involvement as lead counsel in Proxense, LLC v. LG Electronics highlights its engagement with technologies related to proximity-based digital key and secure authentication, as well as wireless communication, including Wi-Fi standards.

While Paul J. Hayes has a significant career history of achieving notable patent verdicts for both plaintiffs and defendants, the firm's single tracked appearance as lead counsel in the Proxense, LLC v. LG Electronics matter was on the plaintiff side. This case, filed in the Western District of Texas in May 2024, is currently ongoing with no public verdict or settlement reported as of May 2025. However, the client, Proxense, LLC, has successfully settled related patent disputes with other major technology companies such as Samsung, Google, and Intel. Hayes's personal track record includes a $55.2 million patent award affirmed by the Federal Circuit and the successful defense of a speech recognition startup against 30 patent infringement claims.

Regarding Patent Trial and Appeal Board (PTAB) practice, no specific high-volume IPR or PGR defense practice is explicitly noted for Patent Litigation Consulting LLC. However, Paul J. Hayes is admitted to practice before the U.S. Patent and Trademark Office. Given the firm's focus on comprehensive patent litigation advice, it is reasonable to infer they would advise clients on PTAB strategies, especially since clients like Proxense, LLC have been actively involved in PTAB proceedings and subsequent Federal Circuit appeals concerning biometric authentication patents. Paul J. Hayes serves as the primary, if not sole, prominent IP litigation partner and practice leader identified for Patent Litigation Consulting LLC.
