Is a projector screen patented?

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

What our index shows
  • 694 US and WO patent publications since 2000 have a title matching “projection screen” or a close variant (our index of 9.7 million patent families; one publication per family).

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a projector screen 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.
