Experience
- Liberty Mutual Insurance Company (CBM2012-00002, CBM2012-00003, CBM2012-00004, CBM2013-00003, CBM2013-00004, CBM2013-00009) – We filed six petitions for covered business method review in connection with our defense of Liberty Mutual against assertions of three different patents relating to determining a cost of insurance based on vehicle monitoring in Progressive Casualty Insurance Co. v. Safeco Insurance Co., et al. After our ex parte reexamination of the originally asserted patent resulted in Progressive’s amendment of every remaining claim while litigation was stayed, we filed CBM petitions challenging the amended claims and two later-asserted patents. The board initiated CBM trials on every claim of these three patents, and, as noted above, we successfully stayed the related district court litigation. On January 23, 2014, the Board issued final written decisions in CBM2012-00002 and -00004 – the Board’s first final written CBM decisions on prior art grounds – invalidating all claims of the patent challenged in those trials. On February 11, 2014, the Board issued final written decisions in CBM2012-00003 and 2013-00009, invalidating all claims of the patent challenged in those trials. And on March 13, 2014, the Board issued a final written decision in CBM2013-00004, invalidating all claims of the patent challenged in that trial. Thus, every claim of every one of these three challenged patents has been held unpatentable in a final written decision from the Board.
