SubscribeAddressing whether a home builder’s floor plans infringed the plaintiff’s architectural copyrights, the US Court of Appeals for the Seventh Circuit affirmed a lower court’s entry of summary judgment against the plaintiff, finding that only a virtually identical design would infringe the plaintiff’s “thin copyright” in its floor plans. Design Basics, LLC v. Signature Construction, Inc., Case No. 19-2716 (7th Cir. Apr. 23, 2021) (Sykes, J.)
Design Basics, described bluntly by the Seventh Circuit as a “copyright troll,” holds copyrights in thousands of floor plans for suburban single-family homes. Design Basics sued Signature Construction (Signature) for infringement of 10 of its designs. Discovery showed that Signature held copies of four of Design Basics’ designs, one of which had been marked up by a Signature employee. Signature moved for summary judgment, relying on a 2017 Seventh Circuit opinion in Basic Designs v. Lexington Homes in which the Court found that Design Basics’ copyright protection in its floor plans was “thin.” The district court granted summary judgment against Design Basics, and this appeal followed.
Relying heavily on Lexington Homes, the Seventh Circuit took the opportunity to clarify the elements of a prima facie case of copyright infringement for works with “thin” copyright protection. The Court explained that to establish infringement, the plaintiff must prove (1) ownership of a valid copyright and (2) copying of original elements of the work. Because ownership was not contested in this case, the Court focused on the copying element. The Court explained that “copying” constitutes two separate questions: Whether the defendant actually copied the plaintiff’s protected work (as opposed to creating it independently) and whether the copying constituted wrongful copying, also known as unlawful appropriation.
Because there is rarely direct evidence of copying, circumstantial evidence may be used to infer actual copying, the Seventh Circuit explained. Proving actual copying by circumstantial evidence requires evidence of access to the plaintiff’s work and evidence of substantial similarity between the two works. The analysis of substantial similarity is not limited to the protected elements of the plaintiff’s work; any similarities may be probative of actual copying. However, the unlawful appropriation prong requires substantial similarities to the protected elements of the copyrighted work. The Court noted that the use of the same term for two different tests has caused confusion, and therefore implemented the term “probative similarity” when referring to actual copying, and “substantial similarity” in the case of unlawful appropriation. The Court went on to explain that in the case of thin copyright protection such as this, proving unlawful appropriation requires more than a substantial similarity; only a “virtually identical” plan will infringe.
The Seventh Circuit then turned to the issues of scènes à faire and merger. Citing its detailed analysis in Lexington Homes, the Court noted that arrangements of rooms in Design Basics’ floor plans were largely scènes à faire, deserving no copyright protection. For example, placement of the dining room near the kitchen and a bathroom near the bedrooms is rudimentary, commonplace and standard, and [...]
