Summary: Patents for Enhanced Electricity Grids

This report analyzes innovation trends in electricity grid technologies, with a focus on patents filed between 2001 and 2022, using data from the European Patent Office (EPO) and the International Energy Agency (IEA).

Key Findings

1. Accelerated Innovation: Electricity grid-related innovation surged dramatically between 2009 and 2013, with an average annual growth rate (30%) significantly exceeding the growth rates of broader low-carbon energy technologies (12%) and overall technologies (4%). Patenting activity subsequently stabilized or grew slowly until recent years.

2. Dominant Regions: The EU27 and Japan have historically led global innovation, with combined patent shares of around 44% in 2011-2022. China, Japan, and the US are considered global leaders, while R. Korea and P.R. China are emerging strong contenders, particularly in smart grids.

   • EU Leadership (Leading Role): Strongest contributors and often show a technological advantage (RTA) in physical grid technologies.
   • Japan (Strong Balance/Skilled Execution): Dominant across most grid segments, showing specialisation and leading in smart grids.
   • **USA (Good Competence/Leading The
