The Copyright Act of 1870, also called the Patent Act of 1870 and the Trade Mark Act of 1870, was a revision to United States intellectual property law, covering copyrights and patents. Eight sections of the bill, sometimes called the Trade Mark Act of 1870, introduced trademarks to United States federal law, although that portion was later deemed unconstitutional after the Trade-Mark Cases.
