As we approach 2020, distributed ledger technologies (DLT) appear likely to have a far-reaching, comprehensive impact on our global economy. But core components of that economy—intellectual property rights in particular—sit in tension with DLT. Copyright owners learned this lesson with the advent of BitTorrent. Patent owners will face similar threats from DLT-based computing platforms executing programs referred to as “smart contracts.” To date, less than 500 U.S. patents have issued with the term “blockchain” in a claim, and none appear to have been litigated. As such, many nuances of DLT patent enforcement have not yet manifested. Nonetheless, even a cursory review of current case law reveals the road to a decentralized utopia is laden with patent-law potholes.
