By 2050, the world population will by 10 billion and 70% will be Urbanites. Technological innovations for sharing assets and resources will be vital for ever-increasing population densities. Implementation of new technologies will be accelerated by IP agreements between multiple parties, each specialist in physical infrastructure, sensors, telecomms or data processing technologies such as AI. Innovators will therefore need to understand what IP can be protected, pitfalls of multi-party agreements, and that any patent-protected technology may later be declared ‘standard essential’. Marks & Clerk will discuss the benefits and licensing obligations arising from IP for Smart Cities.
