There are no requirements on the relative size or location of the copyright symbol, or whether it needs to appear at all.
Not since 1978.
No; notification is not required for protection.
Copyright exists in an item as soon as it is rendered into "permanent" form. The copyright symbol (©) is not needed, although placing it does give the copyright owner an easier time when trying to legally enforce a copyright infringement claim in the US. Before 1978, the symbol was needed to establish copyright under US law. Before about 1960, if you neglected to include the copyright symbol in a published work, it went immediately to the Public Domain. After about 1960, there was a way to remedy that defect, but anything published without the copyright symbol in the US before then was and is free to anyone to use as they see fit.
No. A copyright notice hasn't been required since the laws were changed in 1989.
We use symbols in excel when we need to add a symbol of copyright, trademark symbols, and Unicode symbols etc.
The copyright symbol is a way to indicate that a given work is protected; however, notification is not required for protection. If material you wish to use bears a copyright notification, it should help you find who you need to ask for permission. Without a notification, research will be considerably slower.
Signatories to the Berne Convention (which includes the United States) cannot require formalities. Before Berne, works were only protected if they were published with a copyright symbol and registered with the Copyright Office; since Berne, works are automatically protected as soon as they are "fixed." If you wish to use materials created by someone else, even if they are not marked, you need their permission.
You would need an emulator and the Super Mario 64 game ROM. Due to copyright and piracy issues, I will not disclose where to obtain an emulator or the Super Mario 64 ROM.
There is no requirement to register a copyright or to display a copyright notice for a work to be protected. Copyright protection is automatic, as soon as a work of sufficient originality is "fixed in a tangible medium, perceptible to human eye, machine reader or other device".However if you want or need the additional protection a formally registered copyright can provide, contact the copyright office in your country for the proper procedure and applicable fees.
No, a copyright symbol (©) next to a signature does not necessarily indicate that a painting is an original. The symbol signifies that the work is protected by copyright law, which applies to both original works and reproductions. To confirm if a painting is an original, one would need to consider additional factors like provenance, authenticity certificates, or the artist's statements.
No, creative works acquire copyright upon creation, however, registration establishes legal evidence of the date of creation when issues like infringement arise. Also, the © symbol stands for a registered copyright, so when marking unregistered works, you need to use "Copyright (date)" in full.
Do I need to submit a different copyright application for each work that I do.
