Certicom Corp. (TSX: CIC) has launched a lawsuit against Sony Corp., claiming that the electronics giant infringed on two U.S. patents for digital content protection.
The suit, filed in a Texas court Wednesday, alleges that Sony is using Certicom-licensed digital encryption technology in a long list of its products including PlayStation 3, and certain personal computers.
The first patent violation, it claims, covers access control technology in used in Sony's Blu-ray high-definition products, which include certain DVD players, the PlayStation 3 and VAIO personal computers.
The company said a second digital transmission patent is also being used without a licence in wireless and audio devices such as high-definition televisions and audio equipment.
"We have invested heavily in (elliptic-curve cryptography) research and development over many years and feel strongly that our shareholders deserve fair value from companies using our patented technology," CEO Bernard Crotty said in a release.
"We prefer to resolve these issues through commercial discussions and without litigation. However, at this point we are left with no alternative but to file suit."
Certicom has hired Fish & Neave Intellectual Property Group of U.S.-based law firm Ropes & Gray for the case.
Company shares climbed 61 cents to $4.85 in early-afternoon trading on the Toronto Stock Exchange. In April, Certicom hit a 52-week low of $3.65 during intraday trading.
