How much detail do you need to reveal in an AI-related patent to meet the enablement requirement? Do you need to disclose the training data for the artificial neural network? In this episode I discuss a recent EPO Board of Appeal decision on the topic: T 0161/18 (Äquivalenter Aortendruck/ARC SEIBERSDORF) of 12.5.2020.  For an English translation of the decision's key statements: https://www.bardehle.com/europeansoftwarepatents/knowledge-base/training-of-an-artificial-neural-network/   If you’d like to learn more about software patents in Europe, follow me on LinkedIn: https://www.linkedin.com/in/bastianbest/.
