Roaming services provider Starhome is suing AT&T Mobility, T-Mobile USA and Roamware for patent infringement, claiming the trio have used its technology to enhance international roaming offerings.
The Switzerland-headquartered firm is seeking damages and a ban on further infringement two of its US patents covering global access to mobile subscribers, in a lawsuit filed at the US district court in Delaware.
“Starhome appreciates the significant value our patents confer to our business and intends to aggressively protect our rights,” Neta Bloch, general counsel at Starhome, said in a statement announcing the legal action.
The patents are core elements in Starhome’s Intelligent Call Assistant and Home Short Code services, which the firm says increases carrier’s revenue potential by automatically correcting misdialed international numbers and unrecognized home short codes.
Starhome claims to have developed the patents over the past decade.
An AT&T spokesman said the firm doesn’t “comment on litigation or pending cases.”
