Vitalik Buterin questions rankings
If you're bragging about how many "blockchain patents" your country/company/organization has, you don't understand blockchains.

No, public blockchains don't need patents as everything is public.
However, hybrid blockchains (used to connect private chains and legacy systems to public chains) very much do, as the code isn't public and therefore must be protected, for smaller entities especially.
