The PTO announced today that it has ordered reexamination of U.S. Patent Nos. 6,488,508 and 6,702,585, for information distribution systems in video games, particularly karaoke video games. The ‘508 and ‘585 patents are owned by ADC Technology Inc. of Nagoya, Japan, and are the subject of the litigation ADC v. Microsoft.
The reexaminations were requested by Microsoft, who asserted that each of four references raised a substantial new question of patentability for the ‘508 patent, and that each of three references raised a substantial new question of patentability for the ‘585 patent. The PTO found, however, that not all the references were actually prior art, and limited the reexaminations to Sanyo JP 01-289221 and Bush ‘863 patent.
Neither reference was before the examiner in the original prosecution.
The law suit between ADC and Microsoft was stayed July 10, 2009, by stipulation of the parties, pending resolution of the present reexaminations.

The PTO announced today that it has ordered an ex parte reexamination of U.S. Patent No. 6,875,021 which is owned by ADC Technology and entitled INTERACTIVE COMMUNICATION SYSTEM FOR COMMUNICATING GAME AND KARAOKE SOFTWARE.
The ‘021 patent is the subject of ADC’s sued Microsoft and Nintendo for infringement. As we previously reported, that suit has been stayed pending resolution of the reexaminations for the ‘508 and ‘585 patents.
The request was filed by Nintendo and relies upon a prior art reference that was not before the examiner in the original prosecution.
