In IT, copyright most often applies to software, which can be protected by both copyright AND patent law. Most software-related copyright issues are addressed in detail in end user licensing agreements.
It does not cost anything to receive copyright protection in most cases. For a watch, you would need to seek out a patent to protect your product, not copyright.
You can't usually patent pure software such as games, but they are automatically covered by copyright in any country that signed the Bern Convention (most Western countries). If you really want to try and patent it though, try submitting your patent proposal to the US Patent and Trademarks Office, as they seem to let practically anything have a patent.
No, they're not "public domain" until the copyright of the author expires. Just because they were sent to the patent office and issued as a patent does not changed the copyright ownership or duration. However, an author of a patent application has, by statute, granted a limited right to others to reproduce the patent. Most of the rules in the US Patent Office regarding copyright notice have not been subject to comprehensive update since the 1988 laws were changed to repeal the need to have a proper copyright notice on a publication in the USA if it was to have copyright protection. Copyright of any creative work of authorship is now free, instantaneous and automatic, whether or not the copyright owner knows it or wants to enforce it, without requiring any copyright notice, nor any registration.
You cannot patent a cartoon, although you might patent an ornamental product design based upon the cartoon. Cartoons are generally protected by copyright, not patents. Copyright is free and automatic, in most countries (including the USA), from the moment the first draft is created.
The most commonly used material for traditional board games is cardboard.
The current copyright act is No. 98 of 1978 as amended (most recently in 2002). The patent act is No. 57 of 1978 as amended (most recently in 2002). The trade marks act is No. 194 of 1993 as amended (most recently in 1997).
An intellectual property attorney most commonly deals with cases of plagiarism, copyright issues, misuse of patent material, and illegal pirating of material.
To qualify for a patent, it would need to be innovative and non-obvious, and the patent application process might be more elaborate and expensive than you would like. Copyright might protect designs, say a pattern of intricate piping, but more as a piece of art than a piece of food. You may find that trademark is the most appropriate direction to go in. There are any number of registered baked goods in the world.
