UK court invalidates three Samsung 3G patents

A UK court has invalidated three Samsung patents that cover 3G technology in two rulings in cases between Samsung and Apple, according to court filings. Samsung alleged that Apple infringed on the patents with 3G-enabled devices, including the iPhone 4, iPhone 4S, and the iPad 2 3G, according to court documents. The High Court of Justice, Chancery Division Patents Court in London dealt with the case in two parts. The first part covered two of the patents and the second part concerned the third patent. Justice Christopher Floyd ruled all three Samsung patents invalid.
