There were 1,240 blockchain patents filed last year. That’s not normal. The number of blockchain patent applications, in fact, has grown over 600 percent since 2016. This year, retailing giant Wal-Mart secured blockchain patents for crypto household energy payments, wearable medical records, and a security system. They also filed patents for drone delivery and “autonomous ground vehicle” delivery systems.
Facebook has thrown its hat in the blockchain ring now too, with patents to handle payment authentication and processing. And they’re not the only ones. Visa and Mastercard are busy gathering blockchain patents, as well as IBM, who now holds 42, and Bank of America, leading the pack with 45 live patents.
