Many people ask me about copyright issues – I don’t know why, I’m not a lawyer, but I do have a pretty good knowledge of what you can and can’t do with something that someone else created. Here’s a great Found this through a series of sites:
"In this drawing, I attempt to explain the wonderful world of copyright law. As an aside, I think that all intellectual property (i.e. patent, trademark, copyright, and trade secret) lawyers like writing about copyright. Because we're all familiar with stuff that copyright protects - books, movies, CDs, DVDs, radio, TV, and the like. Even if, like me, they don't practice copyright law." - Erik J. Heels
