BOSTON (Thomson Financial) - Shares of Tessera Technologies Inc. rallied Monday after the San Jose, Calif.-based company said the U.S. Patent and Trade Office (PTO) extended the reexamination of the company's patent related to semiconductor packaging technologies used in the wireless industry.
Tessera said the examiners' decision is known as an action closing prosecution, and gives Tessera the opportunity to respond within one month to questions raised by the PTO examiners. Tessera said it plans to respond.
