A trademark refers to any forms of marks which are registered to the USPTO. These are names, devices, images, and word identifying any goods which can be produce, manufactured, or natural.
Copyright is a way of protecting both unpublished and published literary, artistic and scientific works, and any forms of expressions as long as it is tangible. It means you can touch it, hear it, or see it. An essay, a play, a song, funky original choreography, HTML coding, or graphics can be protected. Laws of copyright grant the creator’s exclusive rights to distribute, display, perform, reproduce, and prepare derivative works publicly.
A patent is another form of IP (intellectual property). The right of a patent in the United States is granted by the USPTO (United States Patent and Trademark Office) to the inventors. This is to prevent others from using, making, selling, importing, or offering sales of such invention over a limited period of time. The law concerning the United States patent is stated in the Patent Act, 35 U.S.C. The act contains clarifications on using jargons resolving some confusion and complexity.
