>Trademark is pretty different from copyright and patents. Trademark is intellectual property, you stated: >intellectual property is an invalid form of ownership and shouldn't exist at all >This is because claiming to be another party or claiming your product is their product is fraud. It would not be fraud, it would be infringement of intellectual property. But what is the practical difference if you manufacture/sell computers under your mark/logo, or if you are an author selling your book and I begin reproducing your book and selling it to the public? What if I begin reproducing Harry Potter original works or even create my own Harry Potter works and adopt the authors copyright pen name?
