Tessera receives PTO Office Action in '627 patent re-exam

SAN JOSE, USA: Tessera Technologies Inc. has received a Final Office Action, dated July 14, 2009, from the US Patent and Trademark Office (PTO) addressing the ongoing ex parte reexamination of Tessera’s US Patent No. 6,133,627 (‘627 patent).

The office action rejected certain claims subject to reexamination and confirmed certain other claims as patentable and valid over the prior art.

In confirming certain claims added in re-examination as patentable, the PTO Examiner considered claim language based on claim constructions that have been applied in Tessera's litigations involving the '627 patent, including Investigation No. 337-TA-630 (DRAM ITC action).

Tessera has until Aug. 14, 2009, to file its response with the PTO.
