Judge: Leonard P. Stark

Court: Delaware District Court

Case Summary:
Steelhead (a non-practicing entity) accused Motorola and Google of infringing the patent US5491834 entitled “Mobile radio handover initiation determination”, issued on Feb 13, 1996, which expired[*] recently. The patent is currently assigned[†] to Steelhead Licensing (source: MaxVal’s Assignment Database) and was owned by BT. 

The patent relates to handover determination between cells in a cellular radio system handling communications between mobile terminals and base stations. The products named Atrix HD and Droid Razr (CDMA/LTE Products) in the suits rely on the patented process to determine mobile device communication conditions for initiating a handover from one cell to another, Steelhead said.

The case has now come to a conclusion as the parties, Google, Motorola and Steelhead have filed a joint motion to dismiss the case and it appears that the parties have reached a settlement. Considering the request, the court ordered a dismissal. At this point, there are no further details available about the settlement.
