Is a pressure cooker lid patented?

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

What our index shows
  • 205 US and WO patent publications since 2000 have a title matching “pressure cooker” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 205 best keyword matches we examined, 63 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: SEB SA (28), FOSHAN SHUNDE MIDEA ELECTRICAL HEATING APPLIANCES MFG CO LTD (11), WMF GROUP GMBH (5), MIDEA GROUP CO LTD (5).
  • Most common patent classes (CPC subclasses): A47J (204), Y10S (26), A23L (9), F16K (5).

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 pressure cooker lid 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.
