Expert Witness Services

Barr Group's engineers are recognized experts in their respective fields of electrical engineering, firmware design, and software development with impressive credentials. When they aren't providing litigation support to lawyers, their skills are applied to the work of embedded software development and real-time system design. Collectively, Barr Group's engineers are the authors of several books and numerous technical articles.

Technical Fluency

Barr Group's engineers are independent-minded experts capable of researching tough subjects and adept at explaining complex technical topics in language familiar to judges and juries. Thus it is not surprising that our consultants have been called on to assist in patent infringement and other technical legal disputes as expert witnesses.

Barr Group's engineers have been called upon in a variety of legal disputes, ranging from intellectual property to product liability. Through reverse engineering and examination of software source code, experts from Barr Group can testify about the design of specific embedded systems, the reason(s) for malfunction of safety-critical products or medical devices, as well the types of process and architecture best practices that could have been used to avoid injury or harm.

Admitted Experts

Several members of the Barr Group team have been admitted to U.S. District Courts as testifying experts in the fields of electrical engineering, embedded systems, and satellite communications. We have experience with all four sides of patent litigation (validity, invalidity, infringement, and non-infringement), including in the Eastern District of Texas and in proceedings at the ITC and PTAB; software source code copyright and trade secret; and automotive products liability.
