Final Rejection of one patent, four more to go


The U.S. Patent and Trademark Office issued a final rejection of one of five patents at issue in the infringement case against the maker of the BlackBerry portable e-mail device, according to an entry posted on the agency’s Web site on Wednesday.

The PTO mailed out notice of the rejection of one of several patents at issue in the infringement case, which threatens to shut down most of Research In Motion Ltd.’s U.S. BlackBerry e-mail service, according to the Web site entry.

No further details about the decision were immediately available. It marked the first “final” rejection of one of the patents at issue in the case, although the PTO previously had issued “non-final” rejections of all five of the patents.
