The legality of patent information services utilizing generative AI technology became a major point of contention and attracted significant attention.
Now, on April 17, 2026, in the cases 2024 (Wa) No. 70565 and No. 70566, a decision in lieu of mediation based on Article 17 of the Civil Mediation Act has been finalized. Consequently, related cases have also been withdrawn, and all cases have concluded.
AI Samurai Inc. also holds patents related to generative AI and considers the protection of intellectual property to be a key management priority. In light of the conclusion of this case, Shirasaka will explain future IP strategies.
Furthermore, Professor Makoto Onizuka from Osaka University will give a lecture titled 'Latest Generative AI: Technical Evolution and Social Applications of Large Language Models.'
