This is a list of notable patent law cases in the United States in chronological order. The cases have been decided notably by the United States Supreme Court, the United States Court of Appeals for the Federal Circuit (CAFC) or the Board of Patent Appeals and Interferences (BPAI). While the Federal Circuit (CAFC) sits below the Supreme Court in the hierarchy of U.S. federal courts, patent cases only have the right of appeal to the Federal Circuit. The U.S. Supreme Court will only review cases on a discretionary basis and rarely decides patent cases. Unless overruled by a Supreme Court case, Federal Circuit decisions can dictate the results of both patent prosecution and litigation as they are universally binding on all United States district courts and the United States Patent and Trademark Office. ==Early cases (before 1900)== *''Tyler v. Tuel'' - Supreme Court, 1810. Held that an assignee of a geographically limited patent right could not bring an action in the assignee's own name. Now obsolete. *''Hotchkiss v. Greenwood'' - Supreme Court, 1850. Introduced the concept of non-obviousness as patentability requirement in U.S. patent law. *''Le Roy v. Tatham'' - Supreme Court, 1852. "It is admitted that a principle is not patentable. A principle, in the abstract, is a fundamental truth; an original cause; a motive; these cannot be patented, as no one can claim in either of them an exclusive right." *''O'Reilly v. Morse'' - Supreme Court, 1853. Influential decision in the development of the law of patent-eligibility (Invalidating method claims for "abstract idea", where steps of method not tied to particular machine). *''Rubber-Tip Pencil Co. v. Howard'' - Supreme Court, 1874. "An idea of itself is not patentable, but a new device by which it may be made practically useful is." *''City of Elizabeth v. American Nicholson Pavement Co.'' - Supreme Court, 1878. "Prior use" does not include experimental use. *''Egbert v. Lippmann'' - Supreme Court, 1881. Held that public use of an invention bars the patenting of it. *''Schillinger v. United States'' - Supreme Court, 1894. Patent infringement against the United States. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of United States patent law cases」の詳細全文を読む スポンサード リンク
