In this haunting Kafka-style retelling of a real European patent appeal, "The Habitual Stranger" follows an unnamed inventor through the labyrinth of the EPO as he seeks protection for a carpooling algorithm based on human routine. What begins as a quest for technical recognition becomes a surreal meditation on bureaucracy, invention, and the fine line between innovation and administration. Based on decision T 2137/21, this episode is a must-listen for anyone navigating the world of AI, mobility data, and patent law.
