Is a pop filter patented?

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

What our index shows
  • 420 US and WO patent publications since 2000 have a title matching “pop filter” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 11 best keyword matches we examined, 6 were published in 2020 or later, and the earliest was published in 2003.
  • Most frequent assignees in those matches: POWER ROBERT (1), MITSUBISHI ELECTRIC CORP (1), LENOVO SINGAPORE PTE LTD (1), AKG ACOUSTICS GMBH (1).
  • Most common patent classes (CPC subclasses): H04R (6), G02B (2), G06F (1), H01P (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 pop filter been patented?” but “has my combination of features been described before?” Consumer electronics are among the most heavily patented areas; the specific circuit, mounting, or interaction is what distinguishes a design.
