Software Patent Expert Witnesses

Start Software Patent Expert Search

Software patent expert witness candidates typically have extensive experience in computer science, software development, computer forensics, electrical engineering, telecommunications, and/or information technology. A software engineer has expertise in programming languages, software development, and computer operating systems, and applies engineering principles to create software systems. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior experience. In addition to technical expertise, a software expert witness must possess the ability to explain complex software issues to a judge and jury.

An intellectual property protection program stops others from using an owner’s intellectual property (e.g., trademark infringement, trade secret, trade dress, patent infringement, copyright infringement) without a licensing agreement. A patent provides the right to exclude others from making, using, or selling an invention for a period of years, in exchange for publishing an enabling public disclosure of the invention. Matters requiring software expert witness services involve intellectual property, notably patent infringement litigation. A software forensic expert can analyze complex software source code to determine if there is evidence to reveal intellectual property infringement or theft. Representative matters that Cahn Litigation Services has searched for software patent experts include:

Litigation support by a software expert witness could include computer software analysis, expert report preparation, depositions, and expert witness testimony in the courtroom. In addition, law firm clients may seek a software industry expert for pre-litigation consulting work. Cahn Litigation Services has many years of experience locating expert witnesses to support software patent matters.
