Tay was a social media chatbot geared toward teens first launched in China before adapting the three-letter moniker when moving to the U.S. The bot, however, was programmed to learn how to talk based on Twitter conversations.
According to "Tools and Weapons: The Promise and the Peril of the Digital Age", which Smith co-wrote with Microsoft communications director Carol Ann Browne, the dust-up was centered around Microsoft's 2016 introduction of a chatbot in the US that it named "Tay".
The singer's legal professionals designed a move on Microsoft in 2016, in accordance to a new autobiogrpahy by tech manager Brad Smith.
When the chatbot began sending out racist tweets, the singer had even more reason for concern.
"An email had just arrived from a Beverly Hills lawyer who introduced himself by telling me: 'We represent Taylor Swift, on whose behalf this is directed to you'".
That's when Swift, who believes Tay is synonymous with her brand, took issue with the plan and had her lawyers sent a message to Microsoft's legal team.
Taylor Swift has had some famous feuds over the years, but it's unlikely that many people thought Microsoft would be on the list of people she's had a disagreement with.
"'The name Tay, as I'm sure you must know, is closely associated with our client'", he writes.
Smith extra: "No, I actually didn't know, but the e mail however grabbed my interest". Smith said that the lawyer argued that the use of the name Tay created a false and misleading association between the popular singer and Microsoft's chatbot, and that it violated federal and state laws.
Her identify, signature and initials are already trademarked and in 2015, she attempted to trademark lyrics from her album, 1989.
Business Insider contacted Taylor Swift's representation for comment on the incident, and whether the matter was resolved to her satisfaction.
