Half of all blockchain patent filings come from IBM, Intel, Walmart, Alibaba, Bank of America, Mastercard & nChain

Half of all blockchain patents have been filed by only seven companies – IBM, nChain, Walmart, Intel, Alibaba, Mastercard and Bank of America. Also, out of the ~1,000 reviewed patent applications, only ~10% have been granted. South-Korean blockchain service provider Coinplug is leading the way with 26 granted patents.

Notably, IBM has applied for more than 100 blockchain-related patents in the last six months. Walmart and Alibaba have also been active. The blockchain space—ideologically rooted in open source—has traditionally been skeptical of companies that patent novel blockchain developments. The vast majority of projects in the ecosystem are open source.
