Nest has responded to Honeywell’s claims of patent infringement:
Despite the fact that Honeywell is an “industrial behemoth” with revenues that exceeded $36 billion in 2011, Nest says the company hasn’t innovated. “That ‘blah-looking controller’ on the market today is very often from Honeywell, which has long dominated the thermostat market, but has yet to generate a device that offers ordinary consumers as much as the Nest Learning Thermostat,” Nest claims.
