Final answer:
In 2017, firms from China and the U.S. accounted for 32% and 20% respectively of the blockchain patents filed with the World Intellectual Property Organization.
Step-by-step explanation:
In 2017, firms from China accounted for 32% and firms from the U.S. accounted for 20% of the blockchain patents filed with the World Intellectual Property Organization.
China's dominance in this area may be attributed to its strong focus on technology and innovation, as well as its large market size and government support for blockchain-related research and development.
The United States, on the other hand, has historically been a leader in technology and innovation, but its market share in blockchain patents may be lower due to various factors such as competition from other countries and differences in patent filing strategies.
