“AI and Patent Law: Understanding the Role of Artificial Intelligence in Inventorship and Patent Applications”
Artificial Intelligence and Patent Law: A Complex Relationship
Last year, in the case of Thaler v. Vidal, the Federal Circuit affirmed that only natural persons (i.e., human beings) can be named inventors on U.S. patents, thereby excluding artificial intelligence from being listed as an inventor per se. 43 F.4th 1207 (Fed. Cir. 2022). Most Courts around the world ruled similarly. But this does not mean that artificial intelligence (“AI”) inventions, including inventions developed with AI as a tool and inventions directed to AI subject matters, are not patentable. To the contrary, according to the U.S. Patent & Trademark Office’s (“USPTO’s”) October 2020 Public Views on Artificial Intelligence and Intellectual Property Policy Report (“2020 Report”), academics and practitioners generally agree that artificial intelligence can represent a subset of computer-implemented technology that can be a subject matter of an invention or used to assist with other inventions. 2020 Report, at iii. Current stakeholders generally agree that the U.S. laws are calibrated to address artificial intelligence inventions. 2020 Report, at iii.
AI-Assisted Inventions and U.S. Patent Law
In fact, U.S. inventorship law is well-positioned to handle AI-assisted inventions on a fact-specific case-by-case basis, according to a majority consensus of policymakers. 2020 Report, at 3. Currently, an AI system’s work is driven by a human researcher/inventor. Regardless of whether an artificial intelligence system is used as a tool to develop an invention, consideration of activities by a natural person that would ordinarily qualify as conception of the invention should be unaffected by such use. 2020 Report, at 5. For example, in AI-based drug discovery, artificial intelligence may help to identify promising compounds, but human input is still required to develop syntheses of the compounds and then test compounds in vitro. By analogy, therapeutic antibody discovery proceeds by inducing an immune response to an antigen in exposed animals or cells, thereby producing antibodies that are subsequently optimized by human research scientists who are named as the inventors; no attempt has been made to confer inventorship to an animal or cell line exposed to an antigen. Natural person(s) also can be named as inventors of AI inventions for the natural person(s)’ contributions where the contributions include designing AI algorithms, implementing hardware to enhance an algorithm, applying methods of preparing inputs for an algorithm, or developing an AI system. 2020 Report, at 2. For now, patent applications should not rely solely on artificial intelligence programs as inventors. Rather, inventorship should be predicated upon the human inventive acts that are using artificial intelligence as tools.
AI-Based Inventions and the USPTO
Inventions directed to Artificial Intelligence subject matters have been examined at the U.S. Patent and Trademark Office (“USPTO”) and issued as patents for many years already. For example, the number of U.S. patent applications for AI-based chemical inventions more than doubled from 2009 to 2019, and issued U.S. patents in the same subject area more than tripled during the same time period. Currently, AI-related inventions typically encompass advances in the AI architecture, computational techniques, hardware/material components, and specific uses of artificial intelligence.
Disclosure Requirements for AI-Based Inventions
No unique disclosure requirements currently exist for a patent application claiming an AI-based invention, and practitioners should refer to the principles in the USPTO’s examiner training materials for computer-implemented inventions. The training materials are as applicable to AI-related inventions as to conventional algorithmic inventions. Written description support for an AI-based invention generally requires sufficient disclosure of at least an algorithm and computer hardware. Further, the description should detail the AI process, including how the AI process is used, and how the AI improves an overall technical process or solves a technical problem. If an inventive aspect includes training an AI process or using a trained AI software, examples of training data sets input into an AI module, how the AI module processes and transform the input, and the data output by the AI process should each be described. The figures should illustrate the hardware and include flowcharts for the AI process to accompany the specification discussion. With respect to enablement, the commercial value of most current artificial intelligence systems is predicated on the predictable behavior of the systems in practical applications. 2020 Report, at 11. Therefore, the patent applications should include an enabling description of the AI inventions taking into consideration the degree to which the inventions are considered no more inherently unpredictable than the underlying AI algorithms. 2020 Report, at 11.
Claims Covering AI Inventions
Claims covering AI inventions need not be treated any differently than other computer-implemented inventions currently examined by the USPTO, and practitioners should consult the January 2019 § 112 Guidance covering examination of computer-implemented inventions when preparing claims to AI inventions. However, patent drafters should focus on avoiding patent eligibility rejections, by ensuring that claims fall within a statutory category of patentable subject matter and striving to meet the 2-part Alice eligibility test. AI inventions have a greater likelihood of being found patentable if claims are directed to how AI is architecturally integrated into a system, the sources of data used as input for an AI system, how AI is distinguishable from other systems, or particular operations within an AI system. By contrast, claims reciting building and testing the use of AI or running an AI algorithm on data are more challenging to qualify as patentable subject matter. 2020 Report, at 3.
