Is a screen protector patented?

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

What this means for your idea

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