What is the use of "all rights reserved"?

Question

Law in IT

On all sites in the footer they write: ©All rights reserved. Does this sign provide any benefit? The site is not registered anywhere, the name and TM are not registered. If I'm not mistaken, at the beginning of my life, there was simply an inscription at the bottom of VK © Pavel Durov. That is, you can simply write ©Vasya Vasilyev on your site and legally the site name and logo cannot be used by third parties without permission?

Answer 1

There is no use for this inscription. Until 1989, when the United States joined the Berne Convention, an inscription was required by US law to show that a given work is under copyright (otherwise it was considered the public domain), since 1989 this inscription is not required, it is copied due to misunderstanding. According to Russian laws, it never made sense.

Answer 2

> the name and TM are not registered
> you can just write © Vasya Vasiliev and legally the site name and logo cannot be used by third parties without permission?
In addition to the answer already given by Vladimir Dubrovin (+1), please catch that you have two things mixed up: property copyright (eng. copyright, denoted by this very “©”) and trademarks (eng. trademark, denoted by “™” or "®" if registered) - while in fact they have nothing to do with each other.
The first refers to creative work, the second to names, logos, etc. They intersect only when the logo itself is complex enough to be a creative work, but even then they operate strictly separately.
