Dont be pedantic, but the whole idea behind the design philosophy of being loud and different to an iphone clone was clearly nokias.
Also nokia designed the n9 like a pillow shape and full screen no buttons..also the display had bezzled gorilla glass...something htc copied with the one x.
In the same way apple doesnt own the colour white or the letter "i" yet everyone and there dog has released products with the same philosophy and naming from smartphones to films.
Companies like humans in general look to see a successfull idea/direction then jump onto the bandwagon...the best ones invent the ideas/trends that everyone else follows.
Camera technology, gps, mapping solutions and gaming are just some of the other technologies nokia brought to smartphones...even if they didnt invent the technologies outright.
Edit also lumia 920 included a curved back...htc introduce a technically different..but visually similar idea on the 8x..stacking or what ever its called.
Feature phones that act like smartphones to hit poorer countries is another area nokia has focussed on...combining technologies such as dual SIM, proxy server web compacting...multitouch and gaming to its asha series..
Alas samsung is also having a crack at that...whether that is copying or not time will tell...samsung is a big enough innovative company to do its own thing...even if they blatantly aped the iphone.
