Android Tethering At Risk in Patent Dispute With Nokia

By  |  1 Comment

In a patent battle between Android smartphone-maker HTC and Nokia, the issue of tethering on one of the world’s most popular mobile platforms may be at risk. Likely, Nokia will seek an import ban on troubled smartphone-maker HTC, but the two companies will probably work out a licensing agreement that will allow both parties to peacefully coexist.

android-tethering[1]“At the United States International Trade Commission (USITC, or just ITC) Nokia has just defeated Google and HTC with respect to the proper legal interpretation of U.S. Patent No 5,884,190 on a “method for making a data transmission connection from a computer to a mobile communication network for transmission of analog and/or digital signals”,” writes Foss Patents

Tethering is the process in which a smartphone shares the 2G, 3G, or 4G data connection–over WiFi, Bluetooth, or a wired USB connection–to another device, like a laptop, tablet, or other WiFi-enabled device that may need an Internet connection. On Android devices, the feature may also be called a mobile hotspot feature.

And while this case in particular deals with Nokia, tethering has become quite a ubiquitous feature on Android that Nokia could potentially seek similar claims against other Android smartphone-makers like LG, Motorola, and Samsung.

Given that this appears to be an Android-wide feature, Google had attempted to be named as a co-defendant on the lawsuit to protect its licensees, but failed. As a a third-party to the lawsuit supporting HTC, Google had asked the court to more narrowly define the scope of Nokia’s claims and patents, but the judge refuse, according to Foss Patents.

Google furthermore argued that “setting the data transmission connection for transmission via the selected operation mode” actually means “setting a connection from the computer to the telecommunication terminal to operate in the same operation mode as the selected telecommunication network”. The judge “expressly reject[ed] HTC’s and Google’s proposed construction” and even made the remark in a footnote that there was a “prior inconsistent admission” by Google and HTC to the contrary. In this context Judge Pender also wrote the following: ”As Nokia argues, the connection of the computer itself refers to the communicatin between the computer and the communication network, not the communication between the computer and the telecommunication terminal, which I note the patent history references separately — two sentences earlier.”

Nokia had already previously settled lawsuits against Apple and BlackBerry, so those platforms may be temporarily safe for now.

It looks like Google’s strategy for acquiring Motorola Mobility in order to leverage Motorola’s patents may not be working after all as it’s not even a party to the lawsuit. Hopefully, its X Phone strategy will fare better.

    I am pretty sure when this is appealed because google was not allowed to enjoin, the outcome would be different. I am surprised there are still some lazy journos quoting FOSSPATENTS for any stuff
