On September 29, 2014, in reexamination proceedings, the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO) affirmed the cancellation of all patent claims asserted against Klarquist’s client Microsoft in a separate case brought by NetView Technologies, Inc. NetView had accused Microsoft’s Excel Services of infringing U.S. Patent No. 7,251,776 (the ‘776 patent) in a 2009 lawsuit it filed in the District of Massachusetts. Klarquist represented Microsoft both in district court and before the USPTO.
