Apple's lawyers have already made the claim that a swipe to the left to move forward is proprietary technology along with their copyrighted and innovative thin rectangle with rounded corners design. Also any design using contrasting white and black, differing shades of gray and or derivatives of red, yellow,and or blue also infringe on Apples copyrights.
are you sure? I understood apple suits were about swipe to unlock.
Also remember apple and ms have some form of settlement agreement going way back.
Their next legal claim will be that touching a computer screen, even if it produces no response by the computer, is a violation of their copyright, and spelling the word “apple” is a trademark violation.
