Study notes for Arnstein v. Porter: professor notes, cold call prep, exam angles, and memory aids.

In a copyright infringement claim, a jury may be required to decide if the defendant copied the plaintiff's work and whether such copying constitutes unlawful appropriation based on ordinary listener perception.
Professor Notes

Arnstein v. Porter is a pivotal case in copyright law that illustrates the necessity for a jury to consider evidence of copying and unlawful appropriation in cases alleging musical plagiarism. The Second Circuit emphasized the importance of viewing evidence in the light most favorable to the plaintiff, thus reinforcing the notion that a reasonable factfinder could infer both copying and the nature of appropriation judged by the ordinary listener's perception. This case also highlights the challenges that arise in establishing access and substantial similarity in the realm of musical works, compelling students to think critically about the standards applied in such cases.

Against the Rule
