Is a wine aerator patented?

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

What our index shows
  • 41 US and WO patent publications since 2000 have a title matching “wine aerat” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 41 best keyword matches we examined, 8 were published in 2020 or later, and the earliest was published in 2001.
  • Most frequent assignees in those matches: BENATI CARLO (2), DUSHINE BORIS (2), AVERILL WALTER J (1), WINE REVEAL LLC (1).
  • Most common patent classes (CPC subclasses): B01F (37), A47G (11), C12G (8), C12H (7).

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 wine aerator been patented?” but “has my combination of features been described before?” Drinkware patents cluster around lids, seals, insulation and add-ons; the specific closure or accessory is usually the point of difference.
