Most people, will, I think be aware of the fact that a lot of large technology companies hold swathes of patents, which are quite often used offensively to stamp on small potential rivals. A side effect of this is that you don't often see the big companies going at each other hammer and tongs, because it would lead to all out patent war and for each patent the big companies infringe, they probably hold one that is being infringed upon. Personally, I think the whole system is silly, which makes it entertaining when war does break out, as in this case. Technically it's HTC vs. Apple, but one of the other bigger forces is backing up HTC, providing patents (weapons) for their battle against Apple. Maybe not a war, but certainly an entertaining patent battle.
