Is a smart thermostat patented?

Short answer: specific designs of a smart thermostat have been patented many times, but "a smart thermostat" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 1,664 US and WO patent publications since 2000 have a title matching “thermostat” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 430 best keyword matches we examined, 143 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: GOOGLE LLC (16), EMERSON ELECTRIC CO (12), GRAND FACADE DECORATION ENG CO LTD (10), LENNOX IND INC (10).
  • Most common patent classes (CPC subclasses): G05D (210), F24F (162), G05B (65), H05B (47).

Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a smart thermostat been patented?” but “has my combination of features been described before?” Household products tend to differ in the mechanism (how something attaches, folds, dispenses or cleans) rather than the basic idea.
