Case No. 4:10-CV-01059-SBA -2- STIPULATION RE: AMENDMENT TO CONTENTIONS

I. AMENDMENT TO TIVO'S INVALIDITY CONTENTIONS PURSUANT

TO PATENT L.R. 3-6

On August 23, 2010, Defendant TiVo Inc. served its Invalidity Contentions on Plaintiffs 

AT&T Intellectual Property I, L.P. and AT&T Intellectual Property II, L.P. On September 15, 

2010, Defendant served its First Amended Invalidity Contentions, which contained one minor 

change, namely the inclusion of a claim element under Defendant’s §§ 101 and 112 defenses. On 

December 3, 2010, Defendant filed reexamination requests for the four patents-in-suit asserted by 

AT&T: United States Patent Nos. 5,809,492 (“‘492”), 5,922,045 (“‘045”), 6,118,976 (“‘976”), 

and 6,983,478 (“‘478”)‘478 patent. The reexamination requests for the ‘045 patent and the ‘976 

patent are based on prior art references which were not of record during the original prosecutions, 

and also not included in Defendant’s original invalidity contentions. 

In connection with its petitions for reexamination of the patents-in-suit, Defendant became 

aware of prior art references significant to patentability that were not included in its original 

invalidity contentions. Defendant has attempted to be diligent concerning discovery of prior art 

during this litigation and does not seek to amend its contentions for any improper purpose. 

Defendant requested and Plaintiffs agreed to allow Defendant to amend its First Amended 

Invalidity Contentions to include the additional references.

II. STIPULATION

THEREFORE, THE PARTIES HEREBY STIPULATE, by and through their respective 

counsel, and respectfully request that the Court find that Defendant has satisfied the good cause 

requirement of Patent L.R. 3-6, and that Defendant shall be permitted to amend its First Amended 

Invalidity Contentions to include additional references.
