I just like to direct you to read the following two reports:
Apple seeks ban on U.S. Nokia imports
Kodak sues Apple and RIM over iPhone and Blackberry
From the headlines, it is perhaps clear that these are serious accusations. Well, the problem is that the boundary of tech companies is getting redefined. For example, traditionally Apple is not a mobile phone manufacturer or Kodak is not in the mobile phone sector either. However, with iPhone, Apple has emerged as a serious player in the mobile phone industry. On the other hand, now a days, mobile phone sets can take good pictures and thus, companies like Kodak has some interest in this sector.
The idea of convergence in technology is happening rapidly. We will see these kind of complains more in the coming years.
