Tbh it's just a good business attitude to stay onside with MS for HTC. It's totally wrong in most peoples eyes, like the whole Novell/MS agreement.
MS are just pulling what they always try to to secure their place (which tbh i can't blame them). The patent laws, infringements and what-not is getting stupid (i read one article that someone managed to "patent" toast in the US

) we've had lots of tech wars in the past the browser wars and the likes, but it seems that now it's a patent war and who can hold the most, look at Google with the purchase of Motorola.
Big companies are buying similar tech or companies with higher tech to add the patents to their own list. The whole "intellectual property" thing is getting stupid. It's putting cases in courts that will last for years, protested by dummy companies with 0 products who bring the cases. There is one i read about that was involving Google where Redhat has stepped in as well to battle the patent suit.
I think for tech to go anywhere they should scrap the patent laws as they are, admitted some thing needs to be put in place, but at the moment patents have such a wide area they can cover, are so ambiguous in terms that they can be put against anything.
Enough of my rant though...
Why i started reading this post was it was also something the recent purchase by MS of Skype sorta brings up the same issues. I think MS no matter what they say bought Skype for the patents they have.
P.S sorry for the kind of necro, just didn't want to start a new post when something similar to the way i was thinking was already posted.
