Functionality Screens, Christopher Buccafusco, Mark A. Lemley

Among intellectual property (IP) doctrines, only utility patents should protect function. Utility patents offer strong rights that place constraints on competition, but they only arise when inventors can demonstrate substantial novelty after a costly examination.

As yet, however, courts and scholars have paid little systematic attention to the ways in which these functionality screens operate across and within IP law.We have four tasks in this …

Much of this difficulty arises from an unclear understanding of the nature of functionality in fashion design. This Article proposes a robust account of fashion’s function. It argues that aspects of garment designs are functional not only when they affect the physical or technological performance of a garment but also when they affect the perception of the wearer’s body. Generally, clothes are not designed or chosen simply …
