Samsung Electronics Co. Ltd. convinced a federal appeals court to uphold a ruling that killed four health technology patents that it was accused of infringing with its Samsung Health smartphone app.

The U.S. Court of Appeals for the Federal Circuit Feb. 12 affirmed a trial court ruling that SmarTen LLC’s patents were invalid because they covered abstract ideas. SmarTen had sued Samsung in 2017 for infringing patents related to weight and exercise monitoring through mobile devices.

The U.S. District Court for the Eastern of Virginia in 2018 ruled that SmarTen’s technologies were abstract because they covered data collection, analysis and display of data, and lacked an inventive concept.

The patents implemented age-old functions of tracking diet and exercise in a new environment, Samsung argued in its appeal.
