Is a card shuffler patented?

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

What our index shows
  • 104 US and WO patent publications since 2000 have a title matching “card shuffl” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 97 best keyword matches we examined, 34 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: SHARK TRAP GAMING & SECURITY SYSTEMS LLC (11), TAIWAN FULGENT ENTPR CO LTD (9), BALLY GAMING INC (7), SHUFFLE MASTER INC (7).
  • Most common patent classes (CPC subclasses): A63F (97), G07F (9), A47B (1), Y10T (1).

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 card shuffler been patented?” but “has my combination of features been described before?” Sports equipment patents tend to cover the grip, impact absorption, training feedback, and how gear is adjusted.
