Cape Town: Tech giant Apple has lost its patent protection for "slide to unlock," in Germany.
The decision, which was first reported on Friday, was handed down the previous day by the Federal Patent Court in Munich.
It invalidated all of Apple's claims for the method of unlocking the screensaver by pushing a slider-button across the screen to the right.
According to News24, judges ruled that "unlocking a device by performing gestures on an unlock image" was unpatentable as granted, and that none of the 14 amendments proposed by Apple could salvage the patent.
Apple has been at war with other tech firm over the web of worldwide patents that make it difficult for each maker of smart-phones and tablet computers to copy one another''s interfaces.
Samsung and Motorola challenged the Apple''s European patent 1964022 and the court declared it invalid, ruling that it was not a technical innovation entitled to protection.
According to the report, Apple is entitled to appeal.
