Aruba Networks said the U.S. Patent & Trademark Office has issued a preliminary re-examination report that rejects all claims of one of the patents Motorola asserted against Aruba in 2007. In rejecting all of the patent's claims, and provided the preliminary finding is made final, the USPTO's decision would invalidate the entire patent.
In 2007, Motorola's subsidiaries Symbol Technologies and Wireless Valley Communications filed a lawsuit in U.S. District Court of Delaware against Aruba, charging Aruba infringed on four of Motorola's patents relating to WLAN technologies. Aruba subsequently filed counterclaims and also requested the Patent Office re-examine all four patents based, among other things, on substantial prior art unearthed by Aruba. The Patent Office agreed to do so, and this recent preliminary report is a result of Aruba's re-examination request.
The other three patent re-examinations are still pending.
