Which countries own the most patents historically?
A historical view of where patent ownership is most concentrated, enables us to better understand how today's current top patent owners in Post-quantum cryptography got to where they are. Or alternatively, which countries used to be a top patent owner in a technology but have since seen their leadership position slip. We track their patent ownership through two decades by tracking patents with an earliest priority year between 2005 and 2025.

Which countries have the largest concentrations of patents in the past compared to now?
Here we view a side-by-side comparison of the previous lead countries (patent families with an earliest priority year between 2005 and 2014) to the current lead countries (patent families with an earliest priority year between 2015 and 2024) both ranked by selected criteria defined in the pull down menu (top right) in Post-quantum cryptography.
