Companies with the most blockchain patents in the United States 2022

* A patent family is defined as a group of patent documents all of which have the same set of priorities. I.e., it is a group of patent documents that protect the same invention across authorities.

The owner of a patent includes all patents owned by a company and its subsidiaries (by at least 50%) based on comprehensive research on corporate structures, M&A, Spin-offs, company names changes, patent transactions. PatentSight also tracks former names of companies and subsidiaries, ongoing mergers and acquisitions, acquisitions of the past, reassignments, companies that have the same applicant, and transliterations by patent offices.

Technology field definition by Swiss Federal Institute of Intellectual Property – ip-search: "The technology field covers distributed ledger, or shared ledger design, of which one form is Blockchain. Blockchain is a decentralized encryption technology, build by a growing list of linked blocks. Each block contains a cryptographic hash of the previous block,a timestamp and transaction data. The technology field also covers various applications of the technology such as Bitcoin, Ethereum, Cryptocurrencies as well as Smart Contracts. Due to common wording, a certain amount of closely related encryption technologies, such as block cipher, hashchaining etc. are at least partly included in this field."
