Paradigm filed an amicus brief in BProtocol Foundation v. Uniswap Labs, arguing against patents that could stifle innovation by monopolizing basic market-making concepts in DeFi.

Executive Summary

Paradigm has filed an amicus brief in the case of BProtocol Foundation v. Uniswap Labs, challenging the patentability of using mathematical formulas for setting exchange rates on blockchains. Paradigm argues that upholding these patents would stifle innovation in the Decentralized Finance (DeFi) sector by granting monopolies over fundamental economic concepts.

The Event in Detail

The lawsuit centers around patents asserted by BProtocol Foundation against Uniswap Labs, specifically U.S. Patent Nos. 11,107,049 and 11,574,291. These patents relate to a "system and method for exchanging and evaluating virtual currency" and cover the Constant Product Automated Market Maker (CPAMM) technology implemented by the Bancor Protocol. BProtocol alleges that Uniswap's versions 1 through 4 of its protocol infringe upon these patents by utilizing a similar CPAMM mechanism. The lawsuit seeks damages and recognition of BProtocol's early work in the DeFi space.

Market Implications

Paradigm's amicus brief highlights the potential negative implications for the broader DeFi ecosystem if BProtocol's patents are upheld. The brief argues that allowing patents on basic market-making concepts would create barriers to entry, raise costs, and slow down development within the DeFi sector. This could lead to increased centralization and reduced competition, hindering the growth and accessibility of decentralized financial services. Conversely, a victory for Uniswap would reinforce the principle that fundamental economic practices and mathematical formulas are not patentable, fostering continued innovation and open-source development in DeFi.
