Written by attorneys · grounded in primary & secondary sources — see below
A doctrine permitting a facial challenge to a law regulating speech when the law prohibits a substantial amount of protected speech judged against its plainly legitimate sweep. The challenger bears the burden of proving that the overbreadth is substantial. A statute that is not substantially overbroad remains enforceable against unprotected conduct even if some hypothetical applications would reach protected speech.
Otis Olsen was cited under a county rule barring any materials on public roads that portray agriculture negatively. He filed a facial overbreadth claim arguing the rule chilled criticism by third parties. The court rejected the claim because Olsen failed to show that protected speech formed a substantial portion of the rule's coverage relative to its valid applications against true threats or fraud.
Olive Okafor challenged federal contribution ceilings as overbroad because they restricted many donors who posed no risk of corruption.

Odilia Okamura brought a facial overbreadth claim against a federal statute criminalizing indecent online communications accessible to minors.

Onyx O'Reilly mounted a facial overbreadth challenge to a statute limiting corporate and union expenditures near elections.

The court upheld the statute after concluding that the challenger had not carried the burden of showing substantial overbreadth relative to the government's anti-corruption interests.
The plaintiff must demonstrate that the law prohibits a substantial amount of protected speech when judged against the statute's plainly legitimate sweep. The existence of some unconstitutional applications is insufficient if the overbreadth is not substantial.

No. A litigant challenging a commercial speech restriction must show that the law is unconstitutional as applied to the litigant's own speech rather than relying on facial overbreadth.
Supporting sources
Yes. The doctrine grants standing to raise the rights of third parties whose protected speech might be chilled even when the litigant's own expression falls outside First Amendment protection.
Supporting sources
A content-based regulation is subject to strict scrutiny on the merits, yet the overbreadth doctrine still requires the challenger to prove that the law's unconstitutional applications are substantial relative to its legitimate sweep before a court will invalidate the statute on its face.
