Garmin Strikes Back in Suunto Patent War with a 5-Patent Countersuit
Suunto filed a September lawsuit against Garmin over five patents (antenna design, respiration-rate sensing, golf-shot detection, etc.). Garmin responded in December with a 218-page countersuit accusing Suunto and its Dongguan Liesheng parent of infringing five different patents and arguing Suunto copied Garmin/Firstbeat tech. The filings hinge on hardware patents like antenna design and GPS-related tech, plus a controversial ‘flashlight in a watch’ patent used as leverage. The piece portrays the case as a legal circus rather than a straightforward tech fight, noting Suunto’s products have improved but predicting the dispute could become mutual patent warfare rather than yielding a clear winner.
