Now that the EPO has upheld the patent, a number of court cases on damages and infringement are slated to take place in the coming months, IPCom said. Among them are a damages case against Apple that is scheduled for Feb. 11 at the Regional Court of Mannheim and an infringement case against Nokia scheduled for May 28 at the Higher Regional Court of Karlsruhe, it said.

IPCom wants the companies to license the patent. "The industry should bear in mind that damages for patent infringement set by the courts can be significantly higher than a license at FRAND conditions," it said.
Founded in 2007, IPCom is a patent license manager with a portfolio of almost 1,200 patents in about 160 patent families in the field of mobile communications, according to its website. It claims 35 of those families are essential to implementation of key mobile communications standards in 2G (GSM), 2.5G (GPRS), 3G (UMTS) and subsequent generations.
