level of abstraction.Copyright. The degree to which a work describes an idea or process in a general rather than concrete way. • Judge Learned Hand posited that from any work one can restate the idea in more and more abstract ways, omitting more and more details, until one is left with an uncopyrightable idea rather than a protectable work of originality. See Nichols v. Universal Pictures Corp., 45 F.2d 119 (2d Cir. 1930).
