Microsoft-InterDigital Patent Fight Update: InterDigital has a few standard essential patents that are required by law to be licensed at reasonable rates. Some Microsoft 3G devices (Lumia phones) use this technology and InterDigital was seeking a ban on these devices for infringement. In April, a court found Microsoft guilty and said that a ban would not be against public interest.
Microsoft subsequently filed a lawsuit on Aug 20 saying that InterDigital was asking for unreasonable rates. On Aug 28, the judge overruled the April judgment saying that there was in fact no infringement. There was no mention of the reasonableness of licensing rates, so that case will likely continue as it has been since 2007, when InterDigital first filed against Nokia, which Microsoft subsequently acquired.
