A working group started in January 2022 with the aim to establish a common understanding of terms and to outline a common practice among EPC contracting and extension states and the EPO. Several aspects are playing a role in the very fast expansion of AI that we see today. For example, processing power has increased significantly and better AI models are available as a tool. Combine that with big data, cloud computing, 5G, etc. and AI can solve technical problems in almost any technical domain. This resulted in the past years in a significant rise of the number of AI-related patent applications.
