Arnstein v. Porter in New Jersey Law

How Arnstein v. Porter applies in New Jersey: state-specific rules, key cases, and bar exam notes for Copyright.

State Approach

New Jersey follows a similar framework to the federal copyright standards established in Arnstein v. Porter, emphasizing the necessity of originality and substantial similarity in copyright claims. The courts examine both the evidence of access by the alleged infringer and the similarities in the contested works.

State Rule
In New Jersey, the rule from Arnstein v. Porter is reflected by requiring both proof of access and substantial similarity to demonstrate copyright infringement, aligning closely with federal standards.
Significant State Cases

Harris v. Emus Records Corp.

The court ruled that the plaintiff must show not only access but also that the works in question are substantially similar to establish copyright infringement.

Gordon v. Nextel Communications, Inc.

In this case, the court clarified that the substantial similarity test involves both qualitative and quantitative aspects of the compared works.

P. Diddy v. Ashanti

The New Jersey court found that merely stylistic similarities between works do not suffice to establish copyright infringement without the requisite showing of access.

Comparison to Federal Law

New Jersey’s approach closely parallels federal copyright law, particularly the two-prong test of access and substantial similarity established in Arnstein v. Porter. However, state courts may interpret 'substantial similarity' with a slightly more nuanced examination of qualitative versus quantitative aspects than some federal circuits.

Bar Exam Note

Understanding the principles from Arnstein v. Porter is crucial for New Jersey bar exam takers, particularly in the context of copyright law questions where access and substantial similarity are interrogated.

Practice Pointers
  • Always establish evidence of access before proving substantial similarity.
  • Be familiar with both qualitative and quantitative assessments of similarity when analyzing copyright claims.
  • Review New Jersey-specific precedents to understand court preferences in copyright cases.
