It's over: Google and Honeywell end thermostat patent battle

The 4-year-old patent dispute between Google/Alphabet's Nest Labs and Honeywell over Nest's thermostat has been resolved.

Clouds are giving way to sunshine in the patent dispute over the Nest Learning Thermostat.

Back in February 2012, Honeywell filed a lawsuit against Nest Labs, the startup-turned-Google/Alphabet property. The lawsuit claimed various patent infringements related to Nest's Wi-Fi-enabled Nest Learning Thermostat, an HVAC controller that relies on algorithms to adapt to your routine over time and auto-adjust temperatures on your behalf.

Things have cooled down since then: The thermostat giants appear to have finally reached some sort of agreement, as noted in a brief joint statement Thursday afternoon.

While the exact details of the agreement remain confidential, the statement does suggest that Nest thermostats will remain on store shelves: "Google and Honeywell believe that this patent accord promotes product innovation and consumer choice in the market for smart home products." Honeywell and Nest did not immediately respond to a request to comment.
