MUMBAI: DJ Nitrogen, creator of the Sharetonesâ„? family of ringtone apps, announced today that it has been granted Patent No. 7,610,044 by the U.S. Patent and Trademark Office. "This is our core process that lets users legally share ringtones between their mobile devices and enables providers to unlock users' music with pre-edited ringtones," said DJ Nitrogen CEO Chris Sindoni. "We believe this is the future of the ringtone business."

The patent covers the method of sharing ringtone content independent of the audio content used to generate the ringtone. DJ Nitrogen refers to this as the recipe-sharing model. The "ringtone recipe" is the meta-data that extracts the ringtone from the full audio track, including start and end points, fade in/out and effects. DJ Nitrogen matches music on a user's phone or media device with the ringtone recipes created by other users. These recipes are stored in the DJ Nitrogen cloud. Each recipe is made available to everyone in the DJ Nitrogen ecosystem who owns the source audio, giving users instant access to a huge and growing selection of ringtones for music they love. The platform is fully compliant with copyright laws because users share only the recipe; they never share the source audio content. In the same manner that users share these recipes, providers can deliver professionally pre-edited recipes to their subscribers using the patented DJ Nitrogen process.

DJ Nitrogen leverages the explosive growth in smart-phones and the trend in full track music downloads to these mobile devices. The ringtone recipes are created and shared by users of the Sharetones ringtone editing applications, including Sharetones for the iPhone. The company's new smart-phone apps, starting with Sharetones for Android, complete the ecosystem loop. They give music fans access to a huge catalog of ringtones, including over 95,000 recipes created by Sharetones users. The recipe matching happens in the background, so smart-phone users just preview and select their ringtones. The patent granted today also covers DJ Nitrogen's process for checking if the source audio sought by the shared recipe is not available on the local device and automatically obtaining a licensed copy of that audio. This enables ringtones to be the point of music discovery, encouraging full track purchases from partner music retailers.
