VeriSign is cleared of infringement allegations on SSL protocol

We successfully defended VeriSign, Inc. in a lawsuit brought by Leon Stambler. The suit alleged infringement of three patents asserted against the Internet security protocol known as SSL and against VeriSign’s digital certificates and payment gateway technology. Stambler was seeking damages and an injunction, claiming that every Internet communication secured using the industry standard SSL protocol infringed his patents. We obtained a summary judgment on one patent, and the jury returned a verdict of no infringement of two of the Stambler patents.
