David S. Benyacar practices in all areas of high-technology law, with specific emphasis on patent litigation and counseling relating to telecommunications products and services, and software-based products and systems.

David has acted as lead litigation counsel on many successful large-scale patent cases, including one in which his numerous presentations to the Federal Trade Commission led to the first FTC complaint (against his client's adversary) based on patent fraud in over 30 years.

In the telecommunications area, he has handled patent cases involving cable television networks and services, broadcast television networks and services, high-speed Internet networks and services, customer premises equipment (e.g., ACD systems, PBXs, voicemail systems, etc.), central office equipment (e.g., switching systems, IVRs, AABS, etc.), telephony services (e.g., directory assistance services, teleconferencing services, calling card services, etc.) and communications protocols (e.g., VoIP, TCP/IP, etc.).

David also regularly counsels high-technology and emerging-growth companies on a broad range of intellectual property and Internet issues, and advises corporate lawyers and investment bankers on corporate intellectual property issues, intellectual property valuations, and the licensing of intellectual property and technology.

Before becoming a lawyer, he had a successful career at AT&T Bell Labs as a UNIX operating system developer, and a systems engineer for various telecommunications services and network management products.
