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.
