Suunto also sues Garmin for patent infringement

The legal battle against Garmin adds a new chapter. In addition to the well-known lawsuit filed by Strava, Suunto has now taken legal action against the American manufacturer in Texas for alleged infringement of five patents related to their sports watches.

Suunto sues Garmin: five patents at stake

Unlike the case with Strava, Suunto's lawsuit against Garmin seems to fall within a more common territory within the technological industry, where disputes over hardware and sensor patents between device manufacturers can occur relatively frequently.

The lawsuit, filed in the Eastern District Court of Texas, alleges that several of Garmin's most popular models, including Marq, Fenix, Epix, Instinct, Venu, and Forerunner, have infringed technologies patented by the Finnish company (now Chinese-owned).

The patents in question cover key functionalities ranging from tracking golf swings to measuring respiratory rate, as well as the design and placement of antennas and antenna assemblies inside the watches.

Suunto argues that Garmin has incorporated these innovations without authorization, thus gaining an unfair competitive advantage in a highly contested market.

The fact that the lawsuit was filed in Texas is not coincidental. The district is known for its favorable track record for plaintiffs in patent cases. Although neither Suunto nor Garmin are headquartered there, the lawsuit states that Garmin distributes its products in the region through retailers and online channels, justifying the jurisdiction.

Suunto's lawsuit adds to the one filed earlier this week by Strava, which accuses Garmin of breaching a 2015 agreement and infringing patents related to Segments and heatmaps. This case seems much less common, as it pits a digital services platform against a device manufacturer over shared cooperation agreements and software functions.

Garmin, for now, has refrained from making public comments on either case, simply stating that they do not comment on ongoing litigation.
