Music recognition service Shazam has been accused of infringing a patent issued to Tune Hunter for its music identification service.
To use Shazam, mobile phone owners simply to hold their handsets up to a speaker playing music for 20 seconds. The service will then identify the track and send a text with artists and title information to the phone.
According to CNET, the patent, awarded to Tune Hunter in 2005 covers 'a music identification/purchasing system, specifically to a method for marking the time and the name of the radio station in portable device such as a key holder, watch, cellular phone, beeper or the like which will allow the user to learn via internet or regular telephone the name of the song, artist and/or music company by matching the stored data with broadcast archive'.
The Shazam app is available for a number of different handsets, including those manufactured by BlackBerry, Apple and Motorola. These companies have also been named in the lawsuit. Tune Hunter claims that Shazam's service violates the patent, and that the other named companies are benefiting from the infringement.
