Representative Matters
  • Won decisions in multiple inter partes reexaminations finding that all challenged claims are invalid.
  • Defended reexamination of patent, initiated by infringer, and won confirmation from U.S. Patent Office that infringed claims are patentable.
  • Developed a position to prove a client was entitled to participate in a patent pool associated with a significant wireless communication standard.
  • Conducted due diligence to support acquisition of technology developed on three continents.  Developed strategies to avoid risks that eight figure purchase price would be jeopardized by ambiguities in technology ownership. 
  • Designed licensing and patent portfolio program resulting in leading technology client's use of competitors to sell its product to gain market acceptance while retaining benefits of technology investment.
  • Guided client in responding to demand for nine figure payment from patentee holding over 100 patents relating to wireless technology, evaluated whether portfolio represented threat or opportunity, and negotiated satisfactory resolution with patent holder.
