A verbal war has been going on between Google and Microsoft, since the internet search giant accused rival tech giants, including Microsoft, of pursuing bogus patent claims to suppress its Android operating system.

A few days back, Google’s chief legal officer David Drummond said that the success of its Android operating system had forced rivals, such as Microsoft, Apple and Oracle, to unite and wage a hostile campaign against its popular operating system. He added that rivals were using bogus patents to push the costs of Android-based devices up.

Mr. Drummond’s comments came after Google lost auctions for thousands of patents held by Novell and Nortel as they were won by a consortium of tech giants, including Microsoft, Apple and Oracle.

But, software giant Microsoft argued that Google had been invited to become a part of the consortium to bid for the patents, but it said ‘no’ to their proposal.

In response, Google said that Microsoft’s offer was not as cordial as it seemed.

In an update to his original blog post, Mr. Drummond said, “It's not surprising that Microsoft would want to divert attention by pushing a false 'gotcha!' while failing to address the substance of the issues we raised.”

According to Mr. Drummond, Microsoft wanted to put Google in a position in which it couldn’t shield itself against their organized attacks.
