HTC fights ‘slide-to-unlock’ in London as Samsung continues patent war with Apple ahead of settlement talks

With court moderated settlement talks between Apple and Samsung executives set to take place within the next 90 days, Samsung has now filed a counterclaim in a California federal court alleging Apple’s iOS devices are infringing eight patents. The counterclaim is part of an original patent infringement lawsuit initiated by Apple in February. Foss Patents reported:

It comes as no surprise that Samsung retaliated with infringement claims. Samsung owns roughly 30,000 U.S. patents. It has from the outset of its dispute with Apple demonstrated its belief that a good offense is the best defense. So far, none of Samsung’s infringement claims against Apple has succeeded anywhere on Earth, despite efforts in nine different countries, but Samsung keeps on fighting.

Apple is also in the middle of patent infringement cases with HTC, which just told a court in London that its touchscreen devices, specifically its “slide-to-unlock” functionality, do not infringe on Apple’s patents. Bloomberg reported today that HTC’s lawyers described the functionality in question as “extremely simple implementations of commonly known techniques.” Apple’s lawyer Simon Thorley argued HTC is “attacking the validity of four patents” and claimed, “It is clear the inventions make the requisite contributions.”

If HTC is successful, it could have an impact in ongoing patent infringement related cases with Apple in Dutch and German courts. The report described the functionality Apple claims is covered in the patents:

HTC is disputing four Apple patents on zooming in and scrolling between photos, multiple touches on the same screen, unlocking phones, and the use of various alphabets in sending text messages.

Apple’s trial with HTC in London is expected to continue until May 4.
