MENELL & CORRENT - DESIGN PATENT IDENTITY CRISIS - BTLJ EDIT - PSM 12-30 12/30/2020 7:58 AM DESIGN PATENT LAW’S IDENTITY CRISIS † †† Peter S. Menell & Ella Corren ABSTRACT Since its emergence during the industrial revolution nearly two centuries ago, U.S. design patent law has suffered from a profound identity crisis. U.S. copyright law did not yet extend to the shape or ornamentation of three-dimensional works. The drafters of the first U.S. design protection regime modeled the law on the British copyright regime for surface ornamentation and sculptural features of three-dimensional articles but confusingly labeled the regime “design patent.” Courts and the Patent Office struggled to interpret protection for “useful” designs against the backdrop of a utility patent regime focused on technological inventions. Further complicating design patent’s role, manufacturers used design patents as a nascent form of trademark protection until federal trademark protection emerged. And in 1870, Congress expanded copyright law to protect sculptural works. In 1902, after a persistent split in the courts and the Patent Office over design patent eligibility for functional designs, Congress clarified that design patents were limited to “ornamental” attributes of articles of manufacture and did not extend to functional attributes. Regional federal circuit courts faithfully limited the design patent regime’s reach, but the tests that they enunciated were cautious and incomplete. In 1982, appellate jurisdiction over design patents shifted to the newly established U.S. Court of Appeals for the Federal Circuit. Later that decade, the Federal Circuit expanded the scope of design patent protection, paving the way for design patent law protection for minimalist and functional features of articles of manufacture. This shift helped to fuel the “smartphone wars” of the past decade. Apple’s design patent claims to rounded rectangles proved to be the most valuable (and profitable) weapon in its seven-year battle with Samsung. This article traces the origins of the ornamentality/non-functionality doctrine and shows how several early cases using the “dictated solely by utilitarian considerations” phrasing to deny design patent protection were misinterpreted to be the standard for determining whether a design was eligible for design patent protection. These decisions merely explained that designs “dictated solely by utilitarian considerations” were clearly outside of design patent eligibility. They did not mean that designs that only partially affected functionality qualified for design patents. Unfortunately, inattentive and protectionist judicial opinions caused the standard to drift far from these holdings and into direct conflict with the clear language and intent of the 1902 design patent amendments and fundamental, overarching intellectual property law principles reflected in the Supreme Court’s seminal Baker v. Selden decision. This article aims to correct this fundamental misinterpretation of intellectual property law. Part II tells the remarkable story of how the effort to transplant England’s design copyright regime to the United States spawned a confusingly labeled “design patent” regime and examines the confusion wrought by this mislabeled law during the mid to late 19th century. It also reveals a period in which design patent law served as a proto-federal trademark DOI: https://doi.org/10.15779/Z38XS5JH75 © 2021 Peter S.

Remnants of that dalliance still confusingly resonate in the design patent system today. Part III explores the 1902 amendments, which unequivocally limited design patents to the ornamental features of articles of manufacture and made clear that they did not extend design patent protection to functional elements. Part IV traces the emergence and distortion of the ornamentality/non-functionality doctrine. The early decisions clearly grasped the need to exclude functionality from design patents. Unfortunately, later cases misapplied some of the language of those cases, resulting in standards that contradict the 1902 (and 1952) Acts as well as the logic reflected in Baker v. Selden and other Supreme Court cases dealing with the structure of the intellectual property system. Part V traces the Federal Circuit’s tilting of the ornamentality/non-functionality doctrine toward overbroad protection of functionality within the design patent regime. Part VI explores the forces that have led the design patent regime astray. Part VII proposes ways of rectifying design patent law’s wayward drift to restore fidelity to the statutory language and the overarching logic of the intellectual property system.
