Tech. Patents LLC v. T-Mobile (UK) Ltd., No. 11-1581 (Fed. Cir. 2012)
Annotate this CaseThe patent describes a “global paging system utilizing a land-based packet-switched digital data net-work (e.g. the Internet) and a feature for permitting subscribers to remotely designate countries in which they are, or expect to be, located.” The patent asserts that prior art was deficient because it did not fulfill the need for a cheap and efficient global paging system that allows users to “remotely input country designations in which they are to be paged,” noting that other than the roaming feature, the receiving user cannot input designated country locations where he expects to be and that the roam feature is expensive. TPL sued more than 100 defendants for infringement: domestic carriers and handset companies, including AT&T, T-Mobile, Sprint, Motorola, and others; software providers, including Microsoft, Yahoo, and Clickatell; and foreign carriers. The district court dismissed foreign carriers for lack of personal jurisdiction and granted summary judgment of noninfringement in favor of domestic carriers and software providers. The Federal Circuit affirmed the judgment of noninfringement to the domestic carriers, stating that the judgment applies to the foreign carriers, affirmed summary judgment of noninfringement to software providers with respect to certain claims, but vacated judgment of noninfringement with respect to others.
