Aruba Networks Inc., which is involved in a patent battle with two Motorola Inc. units, says the U.S. Patent and Trademark Office has kicked out one of the patents under which it's being sued.
The patent office rejected all claims of Motorola's patent 7,173,923, the Sunnyvale, California-based company said in a statement March 17.
In February, Aruba said the patent office had also rejected all the claims of patent 6,973,622. That patent came to Motorola in December 2005 when the Schaumburg-based company acquired Wireless Valley Communications Inc., of Austin, Texas.
Speaking of this most recent communication from the patent office, Michael Attaya said "this is the fourth favorable preliminary report in a row from the PTO." Attaya, from Boston's Cesari & Mckenna, is patent counsel to Aruba.
Aruba was sued in federal court in Delaware in August 2007.
