ST. LOUIS - EntSun -- Liquid Rarity Exchange, LLC (https://rarityx.com/) has filed a patent infringement lawsuit against Securitize, Inc. in the U.S. District Court for Delaware, alleging its real-world asset (RWA) tokenization platform—serving institutional clients like BlackRock, Hamilton Lane, and VanEck—directly infringes foundational LRE patents covering digital asset tokenization, fractionalized ownership, and blockchain-based capital markets infrastructure. LRE seeks injunctive relief and enhanced damages for willful infringement.

The lawsuit comes as Securitize pursues a $1.25 billion public listing through a SPAC merger with Cantor Equity Partners II, Inc. (CEPT) and manages over $3.4 billion in tokenized assets. LRE developed and patented these digital ownership technologies well before today's institutional RWA industry emerged, and previously notified industry participants of its IP, including Cantor Fitzgerald in 2012.
"LRE patented these technologies years before they entered the mainstream," said Keith Grady, Partner at Kean Miller LLP.
