Research shows that the differences between European and Chinese blockchain patent examinations focus on aspects that are “damaging to the public interest”.

According to IAM, the Intellectual Property Asset Management Journal (IAM) recently conducted a comparative study of blockchain patents in Europe and China. Studies have shown that the European and Chinese blockchain patents are similar in that the requirements for novelty, creativity and adequacy of patents are roughly equivalent. At the same time, like the European Patent Law Convention, Chinese patent law requires that patent applications must address technical solutions to technical problems, such as patent applications for technical improvements in blockchain systems. The differences between the European and Chinese blockchain patent examinations focus on the “loss of public interest” aspect. The Chinese Patent Law stipulates that it is not allowed to invent patents that “damage the public interest”. For example, cryptocurrencies such as Bitcoin are considered inventions that are detrimental to the public interest and potentially threaten the stability of the country's financial and monetary systems.
