In the case of Pernod Ricard India Pvt Ltd vs Karanveer Singh Chhabra, the Supreme Court of India considered whether the respondent’s use of the mark “LONDON PRIDE” for whisky prima facie amounted to trademark infringement and passing off.

Will Intellectual Property Still Matter in 2034?

The Pathfinders 2034 report looks ahead to two possible futures for intellectual property — one fragmented and dominated by AI at the cost of human creativity, and another connected, inclusive, and balanced. While it sets out clear action points for governments, it rests on two untested assumptions: that IP drives innovation and creativity, and that it must remain central, merely adapting to new technologies. Without asking whether IP truly encourages human ingenuity in an AI driven world, or recognising its costs to access, public welfare, and follow on work, the vision risks repeating old mistakes. What is needed is a balanced, evidence based view that serves creativity, innovation, and the public good together.
