Slide to unlock was one of the main features Steve liked very much to demonstrate when he released the original iPhone back in 2007. It was a whole new feature the tech world saw at that time and it even made Apple to file a patent application for this cool unlocking mechanism.
How Apple got the Slide To Unlock patent ?
Apple was granted several patents from USPTO (United States Patent and Trademark Office) today and according to PatentlyApple Apple was granted a patent regarding iOS’ Slide to Unlock feature which was of-course introduced first by the Cupertino Company back in 2007.
What is more interesting is the fact that the application was submitted in December, 2005, which is more than a year before the handset was revealed. So after all the bottom-line is that no other company can use it or may be use it and get sued by Apple.
