Is a white noise machine patented?

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

What our index shows
  • 95 US and WO patent publications since 2000 have a title matching “white noise” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 60 best keyword matches we examined, 22 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: IBM (3), HAIER US APPLIANCE SOLUTIONS INC (2), SONY COMPUTER ENTERTAINMENT INC (2), SAMSUNG ELECTRONICS CO LTD (2).
  • Most common patent classes (CPC subclasses): H04R (10), G10K (10), G10L (10), G06F (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 white noise machine been patented?” but “has my combination of features been described before?” Baby and child products are heavily patented and safety-driven; compare the locking, restraint and cleaning features carefully.
