I dont understand copyright laws. There are copies of everything everywhere...what counts as compyright infringement and what is competition? Hell, what is just similar happenstance and is that even illegal!?
I'm not sure what your level of understanding on the subject is, so I'll try to give you a good snapshot overview:
Copyright is one part of intellectual property laws. The three parts are Copyright, Patent, and Trademark. As a general rule, intellectual property laws are a bit of a tangled mess.
Copyright protects your artistic work. Things you write, songs you compose or preform, films you make, things like that.
Under US law, there are certain things that Copyright doesn't protect, this is called "fair use". I'm probably forgetting one, but: parody, educational use, and non-commercial use (with a lot of caveats) are the major parts of fair use. Parody means you're actively mocking something else. Educational Use protects teachers when they are using copyrighted material. Non-Commercial is tricky, but basically means you're not infringing to make money off of it.
Patents protect things you invent. New technology, mostly.
Under US law patents require that you submit your invention to the US patent office. You can elect not to for several reasons, but it will mean your invention is not protected. If your invention is accepted you receive a patent, which allows you to develop your invention without fear that someone else will rip you off.
After submitting your invention, your invention, you may be informed that it infringes on a previous patent, which you must then review and decide to accept that solution, or respond with an explanation that yours differs from the previous patent in some critical way.
Trademark protects, well, trade marks. Logos, product names, and the like.
Unless you really want me to, I'm going to basically leave this at that.
For the most part all of this is part of what's called civil law. That is to say, breaking it isn't actually illegal, but it can (and usually does) result in someone being sued.
Now, wholesale commercial duplication of an existing product, called bootlegging, is illegal (again, in the US (it varies from country to country, though most do have laws against this)). This differs from intellectual property infringement in that you intend to deceive the recipient into believing they're buying an authentic product. It's a specific fraud charge (if I recall correctly).
I hope that cleared things up some. I'll admit, this is one of the more obtuse chunks of the law.
