As the number of blockchain-based patents and patent applications increases, more companies have become interested in pursuing these patents. Other companies still think that blockchain-based inventions are not patentable. To help sort fact from fiction, we have prepared a paper to provide an update on blockchain patents, provide guidance on the types of blockchain inventions that are patentable and how to draft applications to maximize their value. This paper is an update to our prior paper entitled “Patent Strategies for Cryptocurrencies and Blockchain Technology” available here.
