In a recent decision with important implications for artificial intelligence (AI) driven innovation, the Patent Trial and Appeal Board (PTAB) denied a patent for an AI-based medical tool.[1] The refusal was not because the invention was not new or inventive. Rather, the refusal was because the invention did not meet a fundamental rule of U.S. patent law. In Ex parte Michalek, the PTAB specifically acknowledged that the patent claims at issue recited new information about the nexus between certain biomarkers and the development of lung cancer as facilitated by machine learning. In fact, prior to appeal, the applicant had successfully refuted all arguments raised by the patent examiner that the invention was not new or nonobvious. That said, based on U.S. Patent Office guidance and a related example from that guidance, the PTAB still determined the claims were flawed based on the legal principle of subject matter eligibility. Although the facts in this decision concern medical health innovation, the decision is helpful to inform patent strategy for AI-enabled inventions across various disciplines and industries.Continue Reading PTAB Rejects AI-Driven Medical Patent – Not for Novelty, But Eligibility
