Copyright is an automatic right which protects original literary, dramatic, musical and artistic works. A Patent is a registered right that gives the owner exclusive right to features and processes of inventions. A Trade Mark protects logos and signs that are used in relation to a particular type of product or service.
Assuming that a patent is available for the subject matter of your concept, that's the way to prevent others from pursuing the same product concept. A trademark, however, is useful—and often crucial—when you are building a brand for your product or service.
Ing to the Compendium of U.S. Copyright Office Practices, the U.S. Copyright Office may register a claim to copyright in a patent or a patent application, provided that the work contains a sufficient amount of original authorship.
You can have both a trademark and a patent, though they won't be for exactly the same thing. A trademark can protect a creation's name, for example, and a patent can protect the actual creation itself.
The Coca-Cola Corp owns the trademark to the name Coca-Cola, as well as the trademark on the bottle shape, and the graphic representation of their name. These are all things that help distinguish them from other cola brands and define their individual product. Coca-Cola also owns the patent on their formula.
Patents are typically used to protect new and useful machines, processes, compositions of matter, and improvements thereof. In summary, trademarks protect branding and identification of goods and services, while patents protect inventions and prevent others from making, using, or selling the same invention.
Trade marks will protect your brand, but not the invention of the thing you're providing using this brand. If the way your invention works is an important feature of your business, then a patent application may be a valuable form of protection for your business.
The presence of a trademark or trade name in a patent claim is not, per se, improper under U.S. patent law (specifically 35 U.S.C. §112(b) or pre- 35 U.S.C. §112, second paragraph).
Patents are intended to protect inventions of a functional or design nature. Trademarks provide protection for indicators of the source of products and services used in commercial trade, such as words or logos. Copyrights provide protection for literary and artistic expressions.
