A more thorough explanation:

The Berne Convention Implementation Act is a federal law passed in 1988 that made the United States a signatory to the Berne Convention. This happened 102 years after the convention was first opened for signatures. The law deals with copyright and has made some changes to the way copyright works in the United States.

One of the changes made by the Berne Convention Implementation Act is that it ended rigid formalities for registration and marking. This means that copyright owners no longer have to follow strict rules about how to register their work or how to mark it with a copyright symbol. However, registration is still required before U.S. copyright owners can sue for infringement.

For example, if a musician writes a song and records it, they don't have to put a copyright symbol on the recording or register it with the government. But if someone else uses their song without permission, the musician would have to register their copyright before they could sue for infringement.

The Berne Convention Implementation Act has made it easier for creators to protect their work and has brought the United States in line with international copyright standards.
