Is a sous vide cooker patented?

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

What our index shows
  • 58 US and WO patent publications since 2000 have a title matching “sousvide” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 56 best keyword matches we examined, 39 were published in 2020 or later, and the earliest was published in 2008.
  • Most frequent assignees in those matches: HAIER US APPLIANCE SOLUTIONS INC (7), BREVILLE R & D PTY LTD (7), ANOVA APPLIED ELECTRONICS INC (4), MIDEA GROUP CO LTD (3).

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a sous vide cooker been patented?” but “has my combination of features been described before?” Kitchen gadgets are a crowded, mature field; novelty usually sits in one specific mechanism, the material, or how two familiar functions are combined.
