A trademark (also written trade mark or trade-mark) is a type of intellectual property consisting of a recognizable sign, design, or expression which identifies products or services of a particular source from those of others, although trademarks used to identify services are usually called service marks.
Copyright is a type of intellectual property used to allow a creator the right retain ownership and receive credit for their written work. A copyright is similar to a patent as it protects work done by one individual. Copyright law allows a creator to obtain a copyright for their written work.
A corporation is a legal entity that is separate and distinct from its owners. Corporations enjoy most of the rights and responsibilities that individuals possess: they can enter contracts, loan and borrow money, sue and be sued, hire employees, own assets and pay taxes. Some refer to it as a “legal person.”
