BUILD A STRONGER INFRINGEMENT CASE WITH EXPERT ANALYSIS

Randy Winters Helps Translate Innovation into Clear, Defensible Legal Arguments.

Why Expert Witness Support Is Critical in Patent Disputes

Randy Winters provides expert witness services in complex patent disputes, including inter partes review (IPR) and Patent Trial and Appeal Board (PTAB) proceedings, with a focus on software, AI, and emerging technologies. He supports litigation teams through every stage of the patent lifecycle—from infringement analysis and claim construction to prior art evaluation and invalidity challenges. With decades of technical experience and deep understanding of USPTO procedures, Randy translates highly complex technology into clear, persuasive arguments that stand up in court.

As patent litigation grows more technical and more strategic, early involvement of a qualified expert witness is often critical to success. Cases involving software, machine learning, algorithms, or system architectures frequently hinge on nuances in functionality, source code, or claim interpretation. In IPR and PTAB proceedings, where expert declarations are often central to invalidity arguments, credibility, clarity, and deep subject-matter expertise can dramatically influence outcomes. Randy’s ability to demystify technology and anchor it in the legal framework helps attorneys build stronger, more defensible positions from the outset.
