Apple may go on the defensive to protect its 200 touch screen patents against future products from Nokia in the battle for iPhone, an analyst said this morning.

The analyst, Richard Windsor of Nomura, also suspects the two companies are more likely to reach an agreement some time in 2009 than to battle each other in the courts.

Either way, Nokia's attempts to upgrade its s60 platform with touch sensitivity may face some barriers as a result of Apple's patent holdings.

"I think Apple will likely view Nokia as infringing on its user interface patents," Windsor told MarketWatch.
