Senior Vice-President David Drummond didn't mince words in his post on Google's official blog against the "bogus patents" filed against Android's partners including Samsung by rival Apple.

The post on the Official Google Blog had Drummond, Google's Senior Vice President and Chief Legal Officer lashing out about the "organized campaign against Android by Microsoft, Oracle, Apple and other companies waged through bogus patents." He also accused Microsoft and Apple of using the patent wars to drive up the prices of Android smartphones and tablets. The campaign waged by Google's competitors is intended to "strangle" Android, which Google provides free of charge.

The escalating patent wars between Samsung and Apple have been going on for months with both sides accusing the other of patent infringement. Recently Apple prevented the Australian launch of Samsung's Galaxy Tab 10.1 after it filed a suit in Federal Court that Samsung infringed on 10 Apple patents.

Drummond wrote that since Microsoft and Apple have always "been at each other's throats" their working together is extremely suspicious. He revealed that Android had more than 550,000 devices activated every day through a network of 39 manufacturers and 231 carriers.

"But Android's success has yielded something else: a hostile, organised campaign against Android by Microsoft, Oracle, Apple and other companies, waged through bogus patents," he wrote.

"They're doing this by banding together to acquire Novell's old patents (the "CPTN" group including Microsoft and Apple) and Nortel's old patents (the "Rockstar" group including Microsoft and Apple), to make sure Google didn't get them; seeking $15 licensing fees for every Android device; attempting to make it more expensive for phone manufacturers to license Android (which we provide free of charge) than Windows Phone 7; and even suing Barnes & Noble, HTC, Motorola, and Samsung. Patents were meant to encourage innovation, but lately they are being used as a weapon to stop it," Drummond continued.

Apple has launched a series of lawsuits against Samsung in nine different countries. It also has lawsuits against HTC and Motorola for patent infringement. Google has patent suits from Oracle.

"A smartphone might involve as many as 250,000 (largely questionable) patent claims, and our competitors want to impose a 'tax' for these dubious patents that makes Android devices more expensive for consumers. They want to make it harder for manufacturers to sell Android devices. Instead of competing by building new features or devices, they are fighting through litigation."

"Google says we bought Novell patents to keep them from Google. Really? We asked them to bid jointly with us. They said no," Brad Smith, Microsoft's general counsel replied in a tweet. Microsoft's PR team showed a picture of an e-mail that seemed to corroborate his remarks.

Apple Australia and Samsung Australia declined to comment.
