WASHINGTON--(Business Wire)--
On February 29, 2008, the Patent Office issued an Official Action
rejecting Tessera's 6,133,627 patent in ex parte reexamination. The
Patent Office rejected every claim of the '627 patent that is in
reexamination.
Siliconware is represented by its General Counsel Juliette Chan
and by Michael Heafey of Orrick, Herrington & Sutcliffe, who is
leading the reexamination and litigation teams. Siliconware sought
reexamination of five heavily licensed Tessera patents taking
advantage of the Patent Office's new inter partes reexamination
procedures. The latest rejections follow Patent Office actions
previously rejecting related Tessera patents over the last two weeks.
Since February 15, the Patent Office has acted on Siliconware's
reexaminations and has rejected the claims being asserted by Tessera
against an array of chip manufacturers in US District Court lawsuits,
ITC actions, and arbitration proceedings. The patents subject to
Siliconware's reexaminations include Tessera's 6,433,419 and
6,465,893, both of which have rejections in inter partes
reexaminations, and Tessera's 5,852,326 which has been similarly
rejected in ex parte reexamination.
On February 26, the International Trade Commission took the rarely
employed step of staying a hearing based on Siliconware's
reexaminations. The ITC stayed Tessera's investigation against
Spansion, Qualcom, ATI Technologies, Motorola, STMicroelectronics, and
Freescale.
The patents Tessera is asserting against Siliconware are part of
Tessera's "Compliant Chip" license, a portfolio that had been
previously asserted in numerous litigations and which, according to
Tessera, has generated over $250 million dollars in licensing profits.
Also representing Siliconware is Greg Novak and James Murphy of
Novak Druce + Quigg LLP.
