Taiwan smartphone maker HTC has filed a counterclaim against Apple in a Florida court over a patent infringement claim made by Cupertino in March, according to the Wall Street Journal.
In the report Friday, HTC claimed in its lawsuit that Apple's MacBooks and iPhones infringed two patents it had acquired from Hewlett-Packard last year, related to computer networks and desktop remote control management.
Last week, that the Taiwan company did not infringe on four of Apple's European-held patents. It decided three of those four patents were invalid; the only patent that stood related to Apple's photo-management software, but the court found HTC not guilty. The three invalid patents relate to Apple's multi-touch software, alphabet-changing software, and the iPhone and iPad's slide-to-unlock feature.
HTC said in a statement that it "respects innovation and intellectual property rights and will continue to aggressively protect our intellectual property," according to the report.
