Reexamination Ordered on Belden Patent
| August 31, 2009
The PTO granted ex parte reexamination of all four claims of U.S. Patent No. 6,074,503 owned by Belden CDT of Canada. The PTO found that a substantial new question of patentability was raised by each of four prior art references, as well as by various combinations of references.
The request was filed by Superior Essex. This is one of a series of reexamination requests filed by Superior against Belden patents. For a description of the dispute in the PTO and in District Court between Superior and Belden, see our article of July 8, 2009.
PTO Denies TiVo Petition to Vacate Reex. Order
| August 21, 2009
The PTO has denied TiVo’s petition to vacate the PTO’s order of January 7, 2009, granting reexamination of TiVo’s U.S. Patent No. 6,233,389.
TiVo argued that reexamination should not have been granted because the prior art reference relied upon in the request was cited and initialed by the examiners in an earlier reexamination of the ‘389 patent. This, TiVo stated, meant that the earlier reexamination examiners had “considered all portions of the cited references they said were considered.” Accordingly, there was no substantial new question of patentability (“SNQ”).

PTO Applies Extension Rules Strictly
| August 21, 2009
The Director of the Central Reexamination Unit at the PTO has shown again that the rules for extensions of time in reexaminations are strictly applied.
The reexamination request was filed by Microsoft in November 2008, asserting that claims of U.S. Patent No. 5,787,449 were invalid over an earlier patent and article. The ‘449 patent was the subject of i4i v. Microsoft (CA No. 6:07CV113, E.D. Tex.), in which Judge Leonard Davis permanently enjoined Microsoft from infringement of the patent on August 11, 2009.

PTO to Reexamine Plavix® Patent
| August 17, 2009
The PTO granted today an ex parte request by Apotex Corp. to reexamine Sanofi-Aventis’ U.S. Patent No. 4,847,265. The ‘265 patent claims an enantiomer which prevents blood platelets from clotting, thereby reducing the chances for heart attack or stroke.
The request is the latest development in an on-going dispute between Sanofi-Aventis and Apotex regarding the latter’s generic pharmaceutical Plavix®. After Apotex filed an ANDA for Plavix® in 2001, Sanofi-Aventis sued Apotex for infringement of the ‘265 patent. The trial judge ruled in 2007 that the ‘265 patent was valid and enforceable, and this past December the CAFC affirmed those validity and enforceability rulings in favor of the patentee Sanofi-Aventis.

Non-Final Rejections in Reexamination Not Admissible in Jury Trial
| August 14, 2009
The CAFC ruled today that non-final reexamination determinations are “of little relevance” to a jury’s consideration of the obviousness issue. Since the risk of the jury being “confused” by such determinations was high, the CAFC affirmed the trial judge’s exclusion of such a determination at trial.
In that case, Callaway had accused Acushnet of infringing a series of patents claiming golf balls. Acushnet replied by filing inter partes reexamination requests with the PTO, asserting that the patents were invalid over certain prior art.

TiVo “Time Warp” Claims Rejected
| August 4, 2009
The use of reexamination as an aid in litigation was demonstrated again today, this time as a way of promoting a particular claim construction.
In January 2004 TiVo sued Dish Network Corp. in the Eastern District of Texas for infringement of TiVo’s U.S. Patent No. 6,233,389. The ‘389 patent claims a process for simultaneous storage and playback of multimedia data – it allows a television viewer to store one broadcast while watching a different broadcast.
