USPTO records suggest that a Dallas-based law firm associated with a number of NPEs is gearing up to launch new litigation asserting patents received from Intellectual Ventures LLC (IV). Meanwhile, the past couple of months have seen two NPEs managed by two of the firm’s partners add new defendants to litigation.

Texas-based NPE Creswell Holdings LLC has filed suit against HP (4:15-cv-00807), alleging that some of its desktop keyboards infringe a single patent (6,340,803) related to computer keyboard mechanisms. This lawsuit is the second filed by Creswell in its sole litigation campaign, which began in June with a case against Lenovo (4:15-cv-00407). In that complaint, Creswell asserted the ‘803 patent along with two others (6,194,677; 6,318,695) also related to keyboard mechanisms, and the accused products were several of Lenovo’s laptop keyboards.
