CBC News reports on Strava’s lawsuit against Garmin, which alleges patent infringement and breach of contract. Strava claims that Garmin is violating Strava’s patents relating to heatmaps and segments, and also says Garmin’s new developer guidelines require the Garmin logo to be present in every single post and image: “We already provide attribution for every data partner, but Garmin wants to use Strava and every other partner as an advertising platform.” Athletes who rely on both Garmin and Strava are just a bit concerned. (It may be worth mentioning that Strava added restrictions on third-party apps to its own API last year: see DC Rainmaker and The Verge.) Garmin isn’t commenting (pending litigation, etc., etc.).
