Conversant Wireless v Huawei & ZTE: SEP & FRAND Update

Following the decision in Unwired Planet v Huawei, the English Patents Court continues to deliver a steady flow of decisions in relation to standard essential patents (SEPs) and FRAND.

In Conversant v Huawei & ZTE, Mr Justice Arnold has found one of the four patents in suit to be invalid for added matter. If valid, the patent would have been essential and infringed.
