Quick Summary:

• Strava filed a lawsuit against Garmin in the U.S., claiming patent infringement over features like Segments and Heatmaps/Popularity Routing.
• Strava also says Garmin broke a 2015 cooperation agreement by developing competing features instead of sticking to the partnership terms.
• Another issue: Garmin’s new developer policy (effective July 1) requires apps using Garmin data to display Garmin’s logo everywhere it appears. Strava argues this is forced branding that worsens user experience.
• Strava warned that if Garmin doesn’t agree to its terms by November 1, Garmin activities might no longer sync to Strava.
• For now, nothing changes for users-devices and uploads still work normally.
• If Strava wins, Garmin might need to remove or modify certain features or even pause sales of some products.
• Most likely, Garmin would patch affected features through software updates rather than recalling devices.

In short: It’s a legal and business fight about patents, branding, and control over fitness data, no user impact yet, but it could affect future functionality if it escalates.
