Network World - History may look at Android as the tech industry's Helen of Troy: The OS that launched a thousand suits.
Every single week seems to bring new suits and countersuits revolving around software patents allegedly being infringed upon by Android-based smartphones and tablets. Because the history of the Android patent wars is so long and involved, we've created this handy timeline to give you a suit-by-suit chronicle of what companies have sued Android vendors and how Google has tried to counter such suits.
March 2010: Apple gets the ball rolling by filing a lawsuit against HTC for allegedly infringing on 20 Apple patents. At the time Apple says that the patents in dispute relate to the iPhone's patented "user interface and the smartphone's underlying architecture and hardware."
April 2010: Microsoft strikes its first major blow in the Android patent wars by announcing that it has reached a licensing agreement with handset manufacturer HTC to pay royalties to Microsoft in exchange for the right to sell Android-based devices. By this time Microsoft has also started negotiations with Android vendors such as Sony Ericsson about potential licensing deals.
August 2010: Oracle files a patent-and-copyright infringement suit against Google over the use of its Java programming language in Android.
October 2010: Microsoft takes off the gloves and sues Motorola for selling Android-based phones that allegedly infringe upon Microsoft patents. Microsoft general counsel Horacio Gutierrez says that some of the patents in dispute related to Microsoft Exchange ActiveSync while others relate to on-screen displays for signal strength and battery power. Microsoft also buys dozens of smartphone patents formerly owned by Palm, further strengthening its smartphone patent portfolio.
November 2010: Vertical Computer Systems becomes the next company to file suit against vendors over alleged Android patent infringements, this time against Samsung and LG.
March 2011: Microsoft grows even more ambitious in its patent litigation by filing suit against Barnes & Noble over its use of Android as the operating system of its Nook e-reader.
June 2011: Two minor hardware players, Velocity Micro and General Dynamics, come to terms with Microsoft on a licensing agreement similar to the one Microsoft and HTC forged more than a year prior.
July 2011: Google's headaches continue to mount as the company loses its bid to obtain valuable patents formerly held by Nortel to an industry consortium that included Apple and Microsoft. And Google doesn't just lose, it loses badly as its initial bid of $900 million for the patents is easily bested by the consortium's final winning bid of $4.5 billion. In all, Nortel sold more than 6,000 patents that covered technologies such as 4G wireless, data networking and voice.
And the bad news for Google keeps rolling in from there as HTC loses in the International Trade Commission's initial ruling in its dispute with Apple. If the ITC's judgment is made final later this year it could mean a ban on importing HTC's Android phones into the U.S.
