Blockchain Patent Attorney

Forsgren Fisher McCalmont DeMarea Tysver, Minneapolis & Kansas City

Daniel A. Tysver

For over thirty years, Dan Tysver has been helping clients obtain patents on cutting-edge digital technologies. In the past few years, that has meant protecting software, services, and other technologies that utilize blockchains. Inventions in this area can use blockchains in a variety of ways, but frequently these innovations utilize the public, permanent, and verifiable nature of the blockchain to ensure data integrity.

Dan’s Bitlaw website has provided free information on patent law and intellectual property protection for digital technologies for decades. Recently, Bitlaw has added detailed discussions on blockchain technologies, explaining the basic structure of the blockchain, the functioning of smart contracts and how they relate to legal contracts, and the role of DAOs. Bitlaw also describes some of the complications of trying to sue individuals based on activities on the blockchain. Bitlaw also discusses non-fungible tokens, and in particular the copyright issues that frequently arise in the development and sale of NFTs. Finally, Bitlaw website describes the ability to obtain patents on blockchain-related technologies, include a discussion on the types of inventions that have already been patented in this ares.

Blockchain patents are similar to patents on other digital technologies in that the inventions must be new, useful, and non-obvious (see the Bitlaw discussion on patent requirements). In addition, these types of technology must be considered subject-matter eligible before the patent office will grant a patent. Dan has written extensively on subject matter eligibility (see Bitlaw’s Section 101 Index for more information) and also presented numerous legal seminars explaining the intricacies of this arcane area of the law. The important thing to remember is that, in spite of these issues, blockchain inventions are eligible for patent protection in the United States.

Feel free to contact Dan if you have any questions or if you would like to discuss the patent process with him.
