Bancor Initiates Legal Action Against Uniswap Over Patent Infringement
Bprotocol has taken legal action against Uniswap Labs and the Uniswap Foundation in a federal court in the United States, alleging that Uniswap has infringed upon its patented technology that facilitates decentralized trading. The lawsuit focuses on Bancor’s development of the constant product automated market maker (CPAMM) model, which the company claims it invented and patented after its initial development in 2016. The Bancor Protocol, launched in June 2017, is recognized as the first decentralized exchange (DEX) to utilize CPAMM smart contracts.
Bancor Alleges Uniswap Misappropriated DEX Technology
Developers behind Bancor’s $BNT token have accused Uniswap of utilizing their patented CPAMM technology without authorization to create its own competing platform. Uniswap launched its DEX in November 2018, employing the same CPAMM framework as Bancor. The lawsuit asserts that Uniswap has reaped financial benefits from this patented model without any licensing agreement or partnership in place.
Bancor Claims It Pioneered Decentralized Exchange Innovations
The plaintiffs contend that Bancor was the first entity to successfully implement fully decentralized exchanges through the use of smart contracts. They argue that their innovative design removed the necessity for order books and centralized market makers, enabling users to trade tokens directly on-chain without intermediaries. Bprotocol Foundation and LocalCoin Ltd. state that they hold complete ownership of two patents related to this groundbreaking invention, which has been instrumental in advancing decentralized finance (DeFi). The lawsuit claims that Bancor published a white paper in February 2017 that outlined the technology’s functionality and applications, alleging that Uniswap Labs knowingly used this invention without securing the necessary rights. The complaint highlights Uniswap’s ongoing use of CPAMM across various versions of its protocol.
Uniswap Accused of Prolonged Unauthorized Usage
The legal complaint asserts that Uniswap’s initial version, launched in 2018, employed CPAMM smart contracts without permission. Since then, Uniswap Labs has introduced multiple updates to its protocol, including the latest version 4. The plaintiffs maintain that each iteration continues to infringe upon Bancor’s patented technology. Furthermore, Bprotocol posits that the Uniswap Foundation has played a role in facilitating this infringement by endorsing and promoting the platform’s growth, with both parties allegedly aware of the patent’s existence. As a result, the plaintiffs are pursuing legal recourse and recognition of their intellectual property rights.
The Legal Dispute Highlights Challenges in DeFi Innovation Protection
While both Uniswap and Bancor provide similar services that enable users to trade tokens without relying on centralized platforms, Bprotocol’s lawsuit poses a significant challenge regarding the protection of innovations within the DeFi space. This case could potentially redefine the parameters of intellectual property rights in decentralized finance.
Market Impact: Uniswap’s Price Declines
In the wake of the lawsuit, Uniswap’s price has experienced a decline, falling to $5.71, which represents a 3.74% decrease over the last 24 hours. Although the price briefly rose above $6.10 earlier in the day, it has since faced consistent downward pressure. Additionally, trading volume has decreased by 14.18%, signaling a downturn in market activity.
