A trade mark is just a symbol, like that used by coca cola, or the logo of a sports team. Its not really applicable to game making.
A copyright refers to intellectual material, such as raw code or a song. Its more of an idea than an object. Pixelpoop explained it pretty well.
A Patent is like a registered process or an invention. For example, there would be a patent on the chair you are sitting in. Its a plan that describes how to do something, or how something is made. Its registered with your government, and any other governments you wish to register with. It can be quite expensive, and even more so with software, as a search and application must be made.
The thing with a patent is that anyone can then look it up and see how it is done; maybe even copy you. But then you could sue them. So often companies will not bother. For example, the intel chips are not patented as far as i know, so that someone in some far off country doesnt make cheap copies. A patent is only enforcible in the countries it was registered in.
Here is an example. Sonic the hedgehog is a game that is copyright to the author(not the company, no matter what they claim, though they may have a contract that grants them exclusive use). The image of sonic is also copyright to the person that designed it.
The image of sonic was trademarked because it has value. If you put an image of sonic on a shoe, it adds value.
The console that Sonic is played on has a patent. Its something that exists in the real world, and could be pulled apart, examined and copied, so it makes sense to register it to protect the company that designed it. However, parts of it may not be patented for several reasons.
Some of those reasons are that they wish to keep secrets(like the ingredients of coca cola), or that someone else holds a patent on it, and they have bought licencing rights. Other things cannot be patented, like the wiring. A wire is too simple in design to patent.
copyright ----> free
trademark ----> costs money
Patent ----> can cost a lot of money(and you still dont get granted a patent in some cases)
