Veritaseum Capital, a blockchain-based software company has brought a lawsuit against the U.S.-based crypto exchange for infringing its cryptocurrency payment transfer technology patent on 22 September in the U.S. District Court in Delaware. The law firm representing Veritaseum claimed that the crypto exchange had been put on notice of the patent as early as 3 July. A letter had been sent by Veritaseum in the same month notifying Coinbase of its infringement. The software company alleged that Coinbase used the patent for various blockchain infrastructure services and gained substantial profits from it.
