This article discusses the top IP cases to watch in 2012. One of the cases discussed in the article was Akamai Technologies v. Limelight Networks. In late 2011, Finnegan urged an en banc Federal Circuit on behalf of client Akamai, to find entities that perform some, but not all, steps in a method patent claim to be liable for infringement. Joint infringement is an issue that frequently comes up in matters involving software or business method patents with claims that have multiple steps and the outcome may influence how patent prosecutors draft such claims. A decision from the Federal Circuit is due in the middle of 2012.
