EPO Becomes First Authority to Release Guidance Specific to Eligibility of AI/ML
By Aaron Gin --
Artificial intelligence (AI) and machine learning (ML) are specifically addressed in new draft Guidelines for Examination (Guidance) released earlier this month from the European Patent Office (EPO). The Guidance includes two new patentability-related subsections directed to 1) AI/ML; and 2) simulation, design or modeling.
The Guidance first defines AI and ML as being "computational models and algorithms for classification, clustering, regression, and dimensionality reduction, [and which may include] neural networks, genetic algorithms, support vector machines, k-means, kernel regression, and discriminant analysis." Additionally, the Guidance states that such computation models and algorithms relating to AI and ML are "per se of an abstract mathematical nature," indicating that the EPO will likely treat such algorithms as unpatentable by default. This is further reinforced by the organizational structure of the new subsection, which appears as G(II)3.3.1 (AI and ML), falling under the mathematical methods exclusion G(II)3.3.
Generally, under examination by the EPO, applications involving mathematical methods are excluded from patentability unless they are determined to have technical character under Art. 52(1). In assessing whether a mathematical method possesses such technical character, a determination is made whether the invention produces a technical effect that serves a technical purpose. A generic purpose such as "controlling a technical system" is not sufficient to confer technical character to the mathematical method.
The Guidance specifically notes that "artificial intelligence and machine learning find applications in various fields of technology," and highlights examples of a "neural network in a heart-monitoring apparatus" and "classification of digital images, videos, audio or speech signals based on low-level features" as both possessing technical character.
In contrast, the EPO identified the classification of text documents solely based on their textual content and classification of abstract data records without any indication of a particular technical use as not having technical purpose. Furthermore, the EPO treats expressions such as "support vector machine", reasoning engine", or "neural network" as merely referring to abstract models that are "devoid of technical character." Furthermore, the Guidance states that "even if [a] classification algorithm may be considered to have valuable mathematical properties," that alone is not per se a technical purpose.
The new EPO Guidelines for Examination will go into effect on November 1, 2018, and are believed to represent the first official patent examination guidance to specifically address the eligibility of subject matter relating to AI and ML. Going forward, it appears that such applications filed in the EPO should specifically highlight how a specific field of technology is improved by the AI-ML-related mathematical methods in order to best demonstrate technical character.
Nice summary. However the usual format for paragraphs of the EPO Guidelines is G-II,3.3.1
