On Oct.27, 2017, a number of well-known blockchain enterprises from  the United States ，Canada and China launched “the Blockchain Patent Sharing Alliance “ (BPSA) at Stanford university in the Silicon Valley. The world’s first blockchain patent sharing alliance aims to facilitate the global patent sharing as well as promotion and adoption of patent technology.

As the world’s first blockchain patent sharing alliance, BPSA possesses three features of patent protection, cross-chain transactions and smart contract. It is announced that former Commodity Futures Trading Commission chairman Dr. James E. Newsome was appointed to the honorary chairman of the alliance, and former Nasdaq chairman John F. Wallace, academician of the National Academy of Engineering and foreign academician of Chinese Academy of Sciences Ma Zuoping served as one of the honorary advisers.

“Alliance”is one of the main modes for global blockchain researches. The establishment of BPSA is widely regarded as a great benefit to the development of the whole blockchain industry. On the one hand, we can achieve global intellectual property rights sharing and promote the exchange and sharing of technology for every industry; on another hand, we are able to create intellectual property value assessment system to provide the basis for enterprise assets evaluation and intellectual property transactions, establishing global digital patent trading platform based on blockchain to make the effective value-cashing of patent assets possible.

It is foreseeable that, with promotion of BPSA, patent owners, whose rights are guaranteed by the alliance, could take maximum effectiveness of patent assets in the legal, safe and efficient environment; blockchain startups can also benefit more directly from it. They could share the global latest blockchain patent technology through BPSA, which contributes to significantly reduce their spending on patent, and win the favour of the world's big commercial customers to access the global market.
