Shazam Sued by US Company

All is not perfect in Shazam's world. Digimarc, a US-based company that develops software for digital identification and watermarking, has filed suit against Shazam, claiming that the UK-based music tagging service has infringed on 3 of Digimarc's patents, 2 of which date back to 1995. Digimarc has invented technologies that use cameras, microphones and other sensors as ways of identifying digital content. The suit was filed in mid-November in Digimarc's home state of Oregon.
