§909 Mask Work Notice

Summary

An owner of a protected mask work may put a notice on the mask work and on masks or semiconductor chip products that include it. The notice should be placed where people will reasonably see it. The Register of Copyrights will give example ways and places to attach the notice, but those examples are not the only allowed options. The notice is not required for protection but counts as basic proof that the work is protected. The notice must show either the words "mask work", the symbol *M*, or the symbol Ⓜ, and the owner's name or a commonly used abbreviation of it.
