Evermore Park claimed they owned a trademark on the name Evermore, and had since 2015, and thus the release of the album and related merchandise infringed on that name.
This resulted in fairly quick legal action from Evermore Park, who filed suit against Swift for an infringement of trademark.
The kerfuffle all began in December when Taylor Swift released her ninth studio album, titled Evermore.
However, that wasn’t the only lawsuit that would be placed, as T-Swift and her side filed a countersuit against Evermore Park in March, claiming the park had been playing her music without paying the proper royalties.
