Lucas Osborn (Campbell University – Norman Adrian Wiggins School of Law) has posted Pluralizing the PHOSITA in Patent Law on SSRN. Here is the abstract:
Patent law adjudicates invention through a singular fiction: the person having ordinary skill in the art (PHOSITA). That construct now misfires. Courts endow it with encyclopedic knowledge yet cabin its inventiveness. They insist on one mind while modern innovation unfolds through teams and in complex networks. This Article contends that a unitary PHOSITA distorts the patent law’s architecture.
Recent patent doctrine has upgraded the PHOSITA’s cognition without fully rethinking the subject who thinks. Creativity does not scale with credentials alone and rarely resides in solitary actors. Data reveal team-dominant innovation. Social science reveals collaboration can catalyze or corrode insight depending on structure. Moreover, collaboration is not the full story; competition also influences innovation. The PHOSITA, conceived as a solitary being, cannot plausibly proxy this environment.
Courts and commentators largely treat collaboration as a knowledge‑aggregation device rather than a creativity‑modulating force. This Article proposes a pluralized PHOSITA along two orthogonal dimensions. The collaborative dimension distinguishes asynchronous aggregation of prior art from synchronous teamwork. The competitive dimension considers actual races and, more provocatively, introduces “potential competition,” defined as the total population capable of inventing the innovation—thereby recasting inventions in fields with few qualified artisans as less “inevitable” despite high skill. Tested against obviousness theories—“but-for” inducement, cognitive difficulty, and probabilistic success—the framework better filters trivial advances without demanding unadministrable counterfactuals. It preserves the cognitive lens while importing insights from alternative frameworks.
