El 2 de febrero de 2026, D. Kansas (Estados Unidos) conoció un asunto en el que un abogado se apoyó en la herramienta de IA ChatGPT y el expediente registró contenido alucinado.

Qué se alucinó

• Citas falsas de jurisprudencia. Court determined Lexos attributed language to Baldwin Graphic Systems that does not appear in that opinion (quotation fabricated).
• Citas falsas de jurisprudencia. Court found an explanatory parenthetical quoted from AstraZeneca did not exist in that opinion (quotation fabricated).
• Tergiversación de jurisprudencia. Court found citation to AVM Techs. LLC v. Intel Corp. was incorrect (wrong reporter/reference) and that the cited authority does not support the proposition asserted.
• Citas falsas de jurisprudencia. Court found Lexos misattributed a quotation to Rodriguez-Felix that actually appears in Daubert and noted Rodriguez-Felix does not contain the quoted language.
• Citas falsas de jurisprudencia. Court found Lexos quoted Microsoft (i4i v. Microsoft) in support of a point about incomplete claim constructions, but the quoted language does not exist in that opinion.
• Citas falsas de jurisprudencia. Court found Lexos attributed specific language and holdings to Cordis that do not appear in Cordis and noted the patents discussed did not contain the quoted language (misquotation/nonexistent quotation).
• Tergiversación de jurisprudencia. Court found several page-specific citations (e.g., Flexuspine, cited at 879 F.3d 1369, 1375) did not support the proposition asserted and the cited page lacked the discussed admissibility analysis (misrepresented authority).
• Fabricación de jurisprudencia. Court found a cited decision 'Hockett v. City of Topeka, No. 19-4037-DDC, 2020 WL 6796766, at *3' does not exist; quotation and parenthetical attributed to it are fabricated.
• Citas falsas de jurisprudencia. Court found the quoted parenthetical attributed to Liquid Dynamics is not in the opinion (quotation fabricated).
