Custom Software Expert Witnesses

What is a custom software expert witness?

Custom software expert witness candidates typically have extensive experience in computer science, software engineering, computer forensics, electrical engineering and/or information technology. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a software engineer with prior expert witness experience.  

What types of cases require a custom software expert witness?

The software development design process brings customer requirements into an implementable form using a programming language. Software design typically consists of three design phases:

• Interface Design – focus on maximizing usability and user experience
• Architectural Design – similar to the architecture of buildings, is basically a blueprint, and specifies tasks for design teams
• Detailed Design – system components, properties, relationships, processing, algorithms and data structures

Often, matters requiring software engineering services involve intellectual property, such as software patent infringement litigation. A software forensic expert can analyze software source code to determine if there is evidence to reveal intellectual property infringement or theft. A software engineer could also be called in on breach of contract disputes, to consult on technical issues or implementation issues, which could require forensics work. In addition, clients may seek a software industry expert for pre-litigation consulting work.

Custom software expert witness case examples

Exemplary cases have involved:

• custom e-commerce software functionality,
• telecommunications software solutions, and
• a software trade secrets dispute.

What litigation support work might a custom software expert witness be expected to perform?

Software expert witness services could include computer software analyses, research and authoring expert reports, providing expert opinions, and expert witness testimony at deposition and at trial.

Cahn Litigation Services has an earned reputation of providing litigation support and arbitration candidates to perform a search for a custom software expert witness with the perfect balance of technical expertise and testimony experience.
