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.
