The Lanham Act, 15 U.S.C. §§ 1051 et seq., was enacted by Congress in 1946 based on the power granted to it by the Commerce Clause. It provides for a national system of trademark registration and protects the owner of a federally registered mark against the use of similar marks if such use is likely to result in consumer confusion, or if the dilution of a famous mark is likely to occur. The scope of the Lanham Act is independent of and concurrent with state common law.
