Here is my blog on the intense patent war: This week Yahoo sued Facebook for violating 10 very foundational patents for social media / online ads.
Last week, a mobile patents proxy of Microsoft sued Apple for patent infringment
Apple and Samsung have patents suits against each other.
Oracle is after google for Java patent violations in Google.
Microsoft is getting paid of about $5 per Android Mobile device sold by HTC
and the list goes on and on…
Patents are becoming core to business strategy for defense, attack as well as to make money.
Thats why, Google bought Motorola Mobility, Microsoft + Apple consoritum bough Novell patents to arm them up..
