The test for infringement therefore has been given a new dimension. There must be ownership of the copyright and access to the copyrighted work. But there also must be substantial similarity not only of the general ideas but of the expressions of those ideas as well. Thus two steps in the analytic process are implied by the requirement of substantial similarity.

The determination of whether there is substantial similarity in ideas may often be a simple one. Returning to the example of the nude statue, the idea there embodied is a simple one—a plaster recreation of a nude human figure. A statue of a horse or a painting of a nude would not embody this idea and therefore could not infringe. The test for similarity of ideas is still a factual one, to be decided by the trier of fact. See International Luggage Registry v. Avery Products Corp., 541 F.2d 830, 831 (9 Cir. 1976); Williams v. Kaag Manufacturers, Inc., 388 F.2d 949, 951 (9 Cir. 1964).

We shall call this the “extrinsic test.” It is extrinsic because it depends not on the responses of the trier of fact, but on specific criteria which can be listed and analyzed. Such criteria include the type of artwork involved, the materials used, the subject matter, and the setting for the subject. Since it is an extrinsic test, analytic dissection and expert testimony are appropriate. Moreover, this question may often be decided as a matter of law.

The determination of when there is substantial similarity between the forms of expression is necessarily more subtle and complex. As Judge Hand candidly observed, “Obviously, no principle can be stated as to when an imitator has gone beyond copying the ‘idea,’ and has borrowed its ‘expression.’ Decisions must therefore inevitably be ad hoc.” Peter Pan Fabrics, Inc. v. Martin Weiner Corp., 274 F.2d 487, 489 (2 Cir. 1960). If there is substantial similarity in ideas, then the trier of fact must decide whether there is substantial similarity in the expressions of the ideas so as to constitute infringement.

The test to be applied in determining whether there is substantial similarity in expressions shall be labeled an intrinsic one—depending on the response of the ordinary reasonable person. See International Luggage Registry v. Avery Products Corp., supra, 541 F.2d at 831; Harold Lloyd Corp. v. Witwer, 65 F.2d 1, 18–19 (9 Cir. 1988). See generally Nimmer § 143.5. It is intrinsic because it does not depend on the type of external criteria and analysis which marks the extrinsic test. As this court stated in Twentieth Century-Fox Film Corp. v. Stonesifer, 140 F.2d 579, 582 (9 Cir. 1944):

"“The two works involved in this appeal should be considered and tested, not hypercritically or with meticulous scrutiny, but by the observations and impressions of the average reasonable reader and spectator.”"

Because this is an intrinsic test, analytic dissection and expert testimony are not appropriate.

This same type of bifurcated test was announced in Arnstein v. Porter, 154 F.2d 464, 468–69 (2 Cir. 1946), ''cert. denied'', 330 U.S. 851, 67 S.Ct. 1096, 91 L.Ed. 1294 (1947). The court there identified two separate elements essential to a plaintiff’s suit for infringement: copying and unlawful appropriation. Under the Arnstein doctrine, the distinction is significant because of the different tests involved.

"“[T]he trier of fact must determine whether the similarities are sufficient to prove copying. On this issue, analysis (‘dissection’) is relevant, and the testimony of experts may be received to aid the trier of facts. * * * If copying is established, then only does there arise the second issue, that of illicit copying (unlawful appropriation). On that issue … the test is the response of the ordinary lay hearer; accordingly, on that issue, ‘dissection’ and expert testimony are irrelevant.” 154 F.2d at 468 (footnotes omitted)."
