Cryptocurrency exchange Veritaseum Capital, a blockchain-based software startup, has accused Coinbase of infringing on a patent relating to their blockchain technology and is now seeking $350 million in damages. Veritaseum claims Coinbase infringed on its cryptocurrency payment transfer technology patent, known as the “566 Patent,” in a lawsuit filed on Thursday in the United States District Court for the District of Delaware by the law firm Brundidge & Stanger. The patent, according to Veritaseum, centers around “new devices, systems, and techniques” that allow parties to “enforce value transfer agreements” with “little or no trust” in each other, which Coinbase allegedly leveraged for several of its blockchain infrastructure services.
