Intellectual Property Procurement and Counseling

Stephen devotes a substantial portion of his practice to rendering opinions and counseling clients in intellectual property matters. Under his direction, a number of clients have substantially bolstered their competitive position and derived significant additional income from their intellectual property assets. His opinions also have been successfully used both offensively and defensively in litigation.

Favorable judgments and settlements in these cases have resulted in millions of dollars of income for his clients, in some cases fundamentally improving the bottom line of the companies he represented.

On a number of occasions, Stephen has served as intellectual property counsel in connection with transactional matters, involving, for example, the acquisition of a subsidiary or the transfer of technology associated with a joint venture.

He next served as a law clerk and technical adviser to the Honorable Helen W. Nies at the U.S. Court of Appeals for the Federal Circuit from 1983 to 1985.
