Sony is finding itself in another court battle over patents, as Canadian digital security firm Certicom this week filed suit against the company and a handful of its subsidiaries, alleging infringements on patents it holds for elliptic curve cryptography. Elliptic curve cryptography can be used as a way to secure communications between electronic devices, preventing interception or altering of a signal, and Certicom is alleging that Sony's uses of Advanced Access Content System (AACS) and Digital Transmission Content Protection (DTCP) specifications violate its patents. A host of Sony products are named in the suit as infringing devices, including the PlayStation 3, its games, all Blu-ray products, certain high-definition TVs, and DTCP-enabled, i.Link-equipped Vaio PCs.
