Distributed Computing Expert Witnesses

Start Distributed Computing Expert Search

Distributed computing expert witness candidates typically have extensive experience in computer science, software engineering, electrical engineering, computer forensics, and/or cloud computing. A distributed computing expert witness needs to not only have substantive expertise, but must also possess the ability to explain evidence and technology to jurors. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a technologist with prior expert witness testimony experience.

Distributed computing generally falls into one of the following architectures:

• Client–server – a structure that partitions tasks between the providers of a resource or service (servers) and service requesters (clients)
• Three-tier – architectures that move client intelligence to a middle tier so that stateless clients can be used
• n-tier – typically web applications that forward requests to other enterprise services
• Peer-to-peer – uniformly divided responsibilities between devices (peers can serve as both clients and servers)

Often, matters requiring distributed computing expert witness services involve intellectual property, such as patent infringement litigation, software copyright, or trade secret disputes. Litigation support by a distributed computing expert could include infringement analysis, expert report preparation, expert opinion, depositions, and expert testimony in the courtroom.

Cahn Litigation Services is frequently called upon by attorney clients to locate experts that can support distributed computing matters, on behalf of either a plaintiff or defendant. The firm has the experience required to turn a search around quickly and provide qualified candidates that mirror the specifications set by the law firm.
