The decentralised finance (DeFi) world is swaying after Bancor filed a bombshell lawsuit in opposition to Uniswap, accusing the trade big of stealing its patented know-how. Filed in a New York federal court docket, the case may reshape how innovation is protected within the open-source-driven crypto sector. Bancor claims Uniswap constructed its empire utilizing mental property developed almost a decade in the past with out permission or cost.
Conflict of the DEX Titans
Bancor’s father or mother corporations, Bprotocol Basis and LocalCoin Ltd., allege Uniswap Labs and its basis infringed on two U.S. patents for automated market maker (AMM) know-how. The lawsuit claims Bancor pioneered the “fixed product” AMM mannequin in 2016, securing patents by 2017. This technique, which makes use of algorithmic swimming pools for token swaps, grew to become the spine of recent decentralised exchanges (DEXs). Uniswap launched its protocol in late 2018, quickly eclipsing Bancor in market share. Bancor now argues Uniswap’s success stems straight from its patented innovation. “We should act when rivals use our know-how with out authorisation,” stated Bancor undertaking lead Mark Richardson.
Who Invented What?
Bancor’s timeline is restricted: It filed a provisional patent in January 2017, printed a whitepaper weeks later, and launched the primary CPAMM-based DEX by June 2017. The patents cowl strategies for adjusting liquidity pool ratios utilizing good contracts, a course of central to Uniswap’s operations. Alternatively, Uniswap’s protocol debuted in November 2018. Bancor alleges each model of Uniswap (v1 to v4) depends on its know-how. Regardless of this, Uniswap now dominates DeFi, processing $2.8 trillion in lifetime trades in comparison with Bancor’s modest $378,579 in every day quantity.
Uniswap Fires Again
Uniswap Labs swiftly dismissed the lawsuit as “a wasteful distraction.” A spokesperson emphasised that Uniswap’s code has been public for years, including, “We’ll defend ourselves vigorously throughout this era of historic DeFi progress.” Founder Hayden Adams doubled down, calling the go well with “baseless” and hinting at technical variations. “Later Uniswap variations use decentralised hooks and different options Bancor by no means developed,” he argued on X (previously Twitter).

Market Realities
The numbers inform a stark story. Uniswap ranks second amongst DEXs with $3.8 billion in every day trades, whereas Bancor sits at 142nd place. Bancor’s complete worth locked (TVL) has plummeted 98% since its 2021 peak to $58 million, a fraction of Uniswap’s $4.8 billion TVL. Bancor contends this hole stems from unfair competitors. “Unchecked infringement harms all DeFi innovators,” Richardson stated. Nonetheless, critics query why Bancor waited seven years to behave, given Uniswap’s 2018 debut.
Ripple Results
This case may redefine mental property norms in a sector constructed on open-source collaboration. Whereas patent lawsuits are uncommon in DeFi, Bancor’s transfer indicators a shift towards stricter IP enforcement. A ruling in its favour may pressure initiatives to license applied sciences, probably stifling the permissionless ethos that drives blockchain innovation. The lawsuit additionally exams current regulatory wins. Uniswap escaped SEC scrutiny in February 2025, however courts beforehand dismissed a 2023 class motion in opposition to it, citing jurisdictional points. Bancor itself survived a securities lawsuit in 2024 on related grounds.
What Comes Subsequent
Authorized specialists predict a protracted battle. Bancor should show Uniswap’s code straight copies its patents, a problem given technical nuances. If profitable, Uniswap may face hefty fines or licensing calls for, impacting its profitability. Market reactions have been speedy: Uniswap’s UNI token fell 3% to $5.94 post-announcement, extending a weekly lack of 16.58%. Neighborhood sentiment stays divided. Some X customers blasted Bancor for betraying DeFi’s open-source roots; others applauded its stand for inventor rights.
A Pivotal Second for Crypto
Because the case unfolds, its implications will reverberate past courtroom partitions. Will patent protections spur innovation by rewarding creators or fragment DeFi’s collaborative spirit? The reply may decide whether or not the following era of blockchain breakthroughs emerges from open experimentation or guarded labs. For now, all eyes stay on New York’s Southern District Court docket, the place the way forward for decentralised finance hangs within the stability.
