DENVER(BRAIN) Strava is suing Garmin for patent infringement, saying Garmin's segments and leaderboards features violate a patent licensing agreement the two companies reached in 2015.

Garmin made the 2015 agreement with Strava to use Strava Live Segments on its bike computers, watches and software. Garmin and Strava became competitors in March this year when Garmin launched Connect+, a premium subscription version of its free Garmin Connect fitness and health tracking software.

The suit, filed in Colorado District Court on Tuesday, alleges that Garmin violates the terms of the 2015 agreement in part by offering Garmin-branded segments and leaderboards on its devices and software, in addition to the Strava-branded Live Segments.

On the Strava subreddit on Thursday, Stravas Chief Product Officer Matt Salazar pointed to a different dispute, apparently not part of the civil complaint. Salazar wrote that the dispute stemmed from new developer guidelines Garmin issued July 1. Salazar said the new guidelines required the Garmin logo to be present on every single activity post, screen, graph, image, sharing card etc. We have until November 1st to comply, and if not, Garmin has threatened to cut off access to their API, stopping all Garmin activities from being uploaded to Strava.

Salazar said the requirement was blatant advertising that detracted from Strava users experience. Unfortunately we could not justify to our users complying with the new guidelines. As such, we have tried to resolve this situation with Garmin over the course of the past five months, including proposing additional attribution across the platform in a less intrusive way, but to no avail, he said.

The suit does not mention the new developer guidelines. Garmin had no comment immediately. Strava is based in San Francisco and Garmin is headquartered in Kansas. Strava said it sued in the Denver court in part because Garmin has an R&D facility in Boulder.The court on Wednesday set a scheduling conference for Dec. 4.
