Google calls out Apple, Microsoft for using patents as a weapon
Google?s chief legal officer David Drummond took to the company?s official blog this week to rail against what it sees as a hostile, organized campaign against Android by Microsoft, Oracle, Apple and others using patents.

Google says the companies have banded together to acquire patents to make sure Google does not get them, seeking $15 licensing fees for every Android device, attempting to make it more expensive for phone manufacturers to license Android and suing companies that are working with Android.

?Patents were meant to encourage innovation, but lately they are being used as a weapon to stop it,? Mr. Drummond wrote in the blog.

He said the company is determined to preserve Android as a competitive choice for consumers by stopping those who are trying to strangle it through a number of methods, including strengthening its own patent portfolio.
