Network Architecture Expert Witnesses

Start Network Architecture Expert Search
Network architecture expert witness candidates typically have advanced degrees and extensive experience in computer science, software engineering, electrical engineering, computer networking, wireless communication, and/or information technology. Cahn Litigation Services is frequently called upon by law firm clients to locate expert witnesses that can support network architecture matters.
Network architecture refers to the physical and logical design of a computer network, including hardware, software, cabling, device types, layout, physical and wireless network connections. The two types of widely used network architectures are peer-to-peer (P2P) and client/server.
Often, matters requiring network architecture expert witness services involve intellectual property, such as patent infringement litigation, software copyright or trade secret disputes. A forensic expert can provide investigate if there is evidence to reveal intellectual property infringement or theft. Litigation support by a network architecture expert witness could include software analysis, prior art search, an expert report, expert opinion, deposition testimony, and courtroom testimony. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior expert witness experience. A network architecture expert witness needs to not only have expertise, but must also possess the ability to explain technology to lay people. In addition, clients may seek a subject matter expert with industry experience for pre-litigation consultant work.
