Link or it never happened...
it is true that nokia (microsoft) and apple are both bullying htc with patent infringements and that they have recently lost a case in Europe. i have read that much. htc claims they are just buying third party components which supposedly use the patented technology (qualcomm chips, etc.)
------------------commencing rant--------------------
most of these patent wars today are just so bloody ridiculous because most of the technology is so widespread and knowledgeable by now and had it not been patented 5 years ago, the technology would certainly have been discovered by any company in the business today. further more, the companies who sue for patent infringements are content to leave anyone out of the dispute as long as they don't produce a better product than they do - such as the htc one. so instead of using their resources to produce an even better product they try to to eliminate the competition in the court room.
one of the reasons htc is in such dire economic circumstances is because they have had to spend hundreds of millions of dollars in the past few years to acquire patents to protect itself from these predators, and it still pays other companies royalties for every htc sold.
--------------------ending rant--------------------
it is not clear whether this will actually mean prohibiting the htc one in Europe as the OP claims, though.
