Well, that might explain why Android phones and especially those from Samsung looks more and more alike iPhones. From the abstract metal body, chamfered edges, bottom headphone jack to exactly copy of iPhone's True Tone flash, home button fingerprint reader and micro-SIM and nano-SIM.
How many ways can you make a phone? Ohhh rounded edges, now one ever did that before(or right EVERYONE did it even in the 80s)? Bottom headphone jack's more than likely became a standard for docking stations that work with any device. Truetone flash. Its a damn led array(can you patent this for real?). Apple did not even come up with the damn name iPhone was a Cisco name and iPad was a Fujitsu name.
The real thing here is it is hard for an American company to loose in American court rooms against foreign companies. This has given them much success.
I saw a documentary on Steve Jobs a few years back that was made while he was in-between jobs at Next and "back" at crApple. IMHO, he was actually humble then (but that is beside the point). He outright stated in that documentary that crApple stole ideas from quite a few companies.
According to my understanding, if you read George Eastman's bio, he did exactly the same thing. Seems in the US, you get rewarded for stealing from your competitors.
BTW - I live in the US, and I have absolutely no respect for the USPTO. The rule changes it went through a few years back did virtually nothing except hurt the small inventor.
I almost would not be surprised if some company is trying to patent the "Smart Watch" when US patent laws specifically disallow patents on devices that have been in popular media. Think Dick Tracey in this case.
