The New York Stock Exchange (NYSE) has applied to register a trademark for the NFT-marketplace, The Block reports.  

The publication notes that the filing may not be indicative of the exchange's plans to launch a trading floor for non-interchangeable tokens. 

It may speak to the NYSE's concern about using NFT tokens. 

In April 2021, the NYSE created a series of "First Deal" NFT tokens to commemorate the first public trades in the stock of six companies. 

Back then, the exchange sold NFTs through its Crypto.com service.  

The non-exchangeable token series consists of records of the first trades on the exchange by Spotify, Snowflake, Unity, DoorDash, Roblox and Coupang, which have had IPOs in the past few years.
