BLG wins summary judgment of patent invalidity in ski patent defense

February 05, 2009

BLG defended its client K2 by obtaining an order invalidating a patent that had been asserted against K2. The lawsuit was filed by Paul Nelson, who owned a patent related to a short, wide ski. Mr. Nelson had succeeded in licensing the patent to others before suing K2 in a patent infringement lawsuit filed in the Western District of Washington, case number C07-1660RSL. After evaluating K2’s motion for summary judgment, the court concluded that Mr. Nelson’s continuation-in-part patent was only entitled to the benefit of its actual filing date and not that of any of its parent applications. The court further found that Mr. Nelson had sold skis in accordance with the patent more than a year before that date, despite Mr. Nelson’s argument that his sales were merely experimental. With the patent invalidated, K2 prevailed on all claims against it and the case was dismissed.
