Who pays: Courts and regulatory staff who must uncover fabricated citations to intrinsic records, and clients whose patent filings are compromised · group: Clerks and public staff

Although the attorney used a second AI tool to review the initial AI-assisted work, the filing still cited nonexistent portions of a patent’s specification and prosecution history, and inaccurately attributed other information. The USPTO’s Office of Enrollment and Discipline concluded that the attorney violated several professional conduct rules, and the resulting settlement imposed a public reprimand.
