Nokia, which has the largest handset marketshare in India, has filed a patent for a “networking solution which allows a user group to share multimedia contents during a group communication” reports the Economic Times. The patent includes data calls (Voice over Internet Protocol), audio and video calls, messaging and emails, and enables real time sharing of data. More here. I wonder if this has something to do with the launch of Ovi in India. Does anyone know what exactly is holding up the launch of Ovi? Do leave a message, or contact us.

British Telecom has also filed a patent application for a computer telephony system, which enables more secure calls through the Internet – “invention provides a method of securely registering an association between a computer terminal and a selected one of a plurality of communications terminals in a computer telephony system.” [via Business Standard]

A search for more details on these patents led us to search the poorly developed Patent office website: www.patentoffice.nic.in . We couldn’t locate the specific Nokia patent, but we did come across some other very interesting patent filings, which should give you some sense of future technology trends with business implications.

We’ll cover a new patent every alternate day starting next Monday – mostly sticking to patents that have been filed in 2008. We start today, with one on Mobile Advertising:
Rajender Kumar Nangia is trying to patent “a method for advertising a commercial using mobile telephony by providing advertising method using the caller tone and ring tone (audio / video) of a mobile phone to offer an advertisement to a terminal user by outputting a multimedia-advertising message instead of the ring signal and displaying any motion clip on the screen and a system for carrying out the said method.”

The service involves the installation of an application on a Mobile Handset, and will require a data connection (GPRS/3G) for downloading a clip that will be played for the person who is calling.

Hmm…where have I heard of this one before? A couple of months ago, One97 Communications had launched a “Video Ringtone” application called Vringo, which was a little different – you could download a clip, and play it for other Vringo users who call you up. Limited, in its reach, because both users needed to be registered for Vringo, but monetization could have been via video advertising, once the application was installed. This is different from the application mentioned above, which plays the video (advertisement) for the person who is calling.

More patents soon.
