''Markman v. Westview Instruments, Inc.'', 517 U.S. 370 (1996), is a United States Supreme Court case on whether the interpretation of patent claims is a matter of law or a question of fact. An issue designated as a matter of law is resolved by the judge, and an issue construed as a question of fact is determined by the jury. == Background == Herbert Markman patented a system to track clothes through the dry cleaning process using barcode to generate receipts and track inventory. The 7th Amendment guarantees the right to a jury trial in patent infringement cases. The 7th Amendment preserves the right to jury trial as it existed in 1791. There is no dispute that infringement cases today must be tried by a jury as their predecessors were in 1791. However, the court held that the construction of the patent, including the terms of art within its claim, is exclusive within the province of the court. In general, the effectiveness of a particular patent depends on its potential at blocking competitors. The key for a patent holder is getting the proper definition of words used in the patent to allow blocking of the particular troublesome competitive product. Prior to this decision, juries had the responsibility of deciding what the words used in patent claims meant. Opposing results in cases with similar facts were common, and a perception arose that the outcome of such trials was somewhat arbitrary. In ''Markman'', the Court held that judges, not juries, would evaluate and decide the meaning of the words used in patent claims. Judges were to look at four sources for definitions in order of priority: # The written description accompanying the patent claims is most relevant; # The documentation of the history of the patent as it went through the application; # Standard dictionaries of English; # Finally, if all else fails, expert testimony from experts "skilled in the art" at issue. This case has had a significant impact on the patent litigation process in the United States. Many jurisdictions now hold Markman hearings to construe patent claims prior to the start of the actual trial. Patent infringement suits now often settle after this stage of the litigation process. 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「Markman v. Westview Instruments, Inc.」の詳細全文を読む スポンサード リンク
