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.

Newly incorporated NPE Hall Data Sync Technologies LLC began its litigation campaign, suing Apple, Box, Dropbox, Google, Microsoft and SugarSync. The cases assert two patents related to synchronizing duplicate copies of a database (6,539,401, 7,685,506). The defendants in the campaign offer cloud storage services that synchronize information across multiple devices, and those services are accused of infringing the patents-in-suit.
