Late last year, Rovi sued Toshiba, alleging that it infringes two patents covering V-Chip technology, U.S. Patent Nos. 6,305,016 and 6,701,523.  Toshiba has now replied to that allegation by requesting reexamination of both Rovi patents (see ex parte Request Nos. (16) & (17)).

The winner for the most reexaminations requested was TiVo who filed requests against seven Microsoft TV programming patents (see ex parteRequest Nos. (3) to (9)).

Finally, Xilinx’s assault on Intellectual Venture patents continued last week with requests filed against IV’s U.S. Patent Nos. 6,993,669 and 6,408,415 (see inter partes Request No. (3) & ex parte Request No. (31)). (more…)

Here is the latest installment of Reexamination Requests from our friends at Westerman, Hattori, Daniels & Adrian….

Intellectual Ventures shook up the patent world in December when it filed three separate infringement suits against a series of large electronics companies.  In one of the cases, Intellectual Ventures accused Altera, Microsemi and Lattice Semiconductor of infringing four patents programmable logic devices.  On Tuesday of last week, Intellectual Ventures filed an amended complaint to add Xilinx as a defendant.  Well, Xilinx is wasting no time, and on Friday it asked the Patent Office to reexamine one of the five patents-in-suit, U.S. Patent No. 6,272,646.  Requests for reexamination of the other four patents may come soon (see inter partes Request No. (8)).
