Strava Files Lawsuit Against Garmin Over Patent Infringement Claims

Strava has filed a major lawsuit against Garmin, marking a surprising turn for two long-time partners. The claim asserts that Garmin misused Strava’s patented features without permission. This case highlights how closely technology, data, and fitness now intersect. For athletes, developers, and tech watchers, we must track what comes next.

Background on Both Companies

Strava runs one of the world’s top fitness tracking apps. Millions of runners, cyclists, and athletes use it to record activity, compare performance, and connect socially. Garmin is a leading maker of GPS devices, smartwatches, and fitness hardware. Its sensors and wearables feed data into apps like Strava. For years, Garmin and Strava worked together. Many Garmin devices allow users to sync their workouts to Strava automatically. That collaboration made each platform stronger,  until now.

Details of the Patent Infringement Claims

Strava claims Garmin violated two key patents: one for segments, and another for heatmaps/route popularity mapping.

• Segments: These let users define route sections and compare time efforts across rides or runs. Strava applied for its segment patent in 2011, and it officially received approval in 2015.
• Heatmaps & popularity routing: This covers maps showing which routes are most used by other users, and using that data to suggest routes. Strava’s patents in this area were filed in 2014 and 2016.

Strava says Garmin expanded its use of these features beyond what a prior agreement allowed. The complaint alleges Garmin studied Strava’s implementation and then built rival features into its own devices and platform.

Legal Filing and Court Proceedings

The lawsuit,  Strava, Inc. v. Garmin Ltd et al, was filed on September 30, 2025, in the U.S. District Court for the District of Colorado. In its complaint, Strava is asking for a permanent injunction to stop Garmin from selling products that include the disputed features, arguing that monetary payments alone can’t make up for the harm.

Strava also says Garmin breached a Master Cooperation Agreement (MCA) signed in 2015. Under that agreement, Garmin had limited permission to use some Strava features, but Strava claims Garmin exceeded those limits. As of now, Garmin has not publicly responded to the detailed allegations.

Garmin’s Response and Possible Defense

Garmin has stayed mostly silent, stating only that it does not comment on pending litigation.

Potential defenses may include:

• Questioning the validity of Strava’s patents (especially if similar tech existed earlier)
• Arguing that Garmin had legal rights under the MCA
• Claiming that the features are sufficiently different or do not infringe

Because Garmin introduced heatmap-like features in 2013, before some Strava patents were filed, that may be a point Garmin could use to challenge the validity.

Impact on the Fitness Tech Industry

This lawsuit shakes the foundations of how fitness data and device features are shared. If Strava succeeds in stopping Garmin from using these functions, other companies may also rethink licensing, collaborations, and patent strategies.

Developers might become more cautious before building features that resemble those of major platforms. Hardware makers may worry about patent exposure when offering features users expect. Investors will watch closely, as legal risk becomes more real in fitness tech. For users, this case raises concerns: could syncing break? Will features disappear? Will access to data change?

Past Legal Battles in the Sector

Patent disputes are not new in tech. Earlier, Garmin faced legal challenges in different fields (e.g., sonar patent suits). Some wearable tech firms, like CardiacSense, also have ongoing suits against Garmin.

The outcomes of those cases show that courts often scrutinize when patents were filed, prior art, and how clearly the patents define their claims. In many cases, judgments hinge on narrow technical detail rather than broad concepts.

What’s at Stake for Strava and Garmin

For Strava, the stakes include:

• Regaining control over key features
• Damages (lost licensing or revenue)
• Protecting its brand and innovations
• Setting a precedent for how partners must treat their technology

For Garmin, the risks are:

• Being forced to disable or alter features on many devices
• Financial losses if an injunction or damages are awarded
• Damage to reputation as an innovator
• Complicated product redesigns and user backlash

Because the features in question touch many Garmin devices (watches, cycling computers, etc.), the impact could be deep.

Conclusion

The move in which Strava files this lawsuit against Garmin marks a turning point in fitness tech. What began as cooperation may end in court. The conflict highlights how essential features, data, and patents have become in this industry. We should watch the legal battle closely. It will tell us how far companies can push technology, data sharing, and innovation, and whether big players will respect the intellectual property they once licensed.
