Many times a consumer purchases products from the same manufacturer based on past experience that the manufacturer has high quality items and therefore this item will probably be just as good. In short, a trademark will help your customers distinguish your products from your competitor's product. A trademark can be protected either through federal or state law.
Federal protection gives the mark nationwide protection.
One of the requirements for federal protection is that the trademark be used in interstate commerce. Otherwise, the mark can be protected only under state law. Trademarks can be placed into 1 of 4 categories. Arbitrary marks are terms that do not convey any description of the characteristic or the nature of the product. Arbitrary marks are usually coined marks.
