VERNON HILLS, Ill.-Telular Corp. said the U.S. Court of Appeals for the Federal Circuit upheld a lower court’s affirmation of certain Telular patents in Alliance Research Corp. vs. Telular Corp. The case now goes back to the district court to determine damages.
Alliance Research, renamed Ora Electronics Inc., brought the lawsuit against Telular in February 1994. Alliance sought a declaratory judgment for invalidity and non-infringement of Telular’s parent 4,658,096 patent and its two continuation patents, 4,922,517 and 4,775,997.
Ora did not comment on the matter.
Telular said the intellectual property consists of an interface system for interfacing a telephone-type device, such as a standard telephone, fax machine, computer modem, alarm reporting system or private branch exchange with a conventional cellular-type radio transceiver. The system converts tone-dial or pulse-dial inputs from the telephone into a serial data stream to be stored in the transceiver and transmitted.
Late last month, Telular announced a similar ruling in Arthur L. Serrano and Andrew W. Holman vs. Telular Corp.
