WILMINGTON, Del. - Efforts by patent infringement defendant Hewlett-Packard Co. (HP) to block an amended complaint were rejected March 28 by a Delaware federal judge, who agreed with a plaintiff that the proposed filing adequately alleges the elements of a willful infringement claim (St. Clair Intellectual Property Consultants Inc. v. Hewlett-Packard Company, No. 10-425, D. Del.; 2012 U.S. Dist. LEXIS 42749).
