Country darling Taylor Swift and American Greeting Corp. are being sued in federal court for trademark infringement and other violations by a company called Blue Sphere Inc., according to Cleveland.com.

The California based company operates as the brand "Lucky 13" and has filed a lawsuit accusing American Greetings and Swift of "piggybacking on the worldwide success and goodwill of their 23 year-old brand to sell greeting and other products."

A court document states that "Swift and American Greetings used 'Lucky 13' to market and sell greeting cards, through the sponsorship of the 'Lucky 13' Sweepstakes contest through at least the [American Greetings-sponsored] www. Taylorswiftcards.com website, without authorization."

The lawsuit states, "Ms. Swift - who has been photographed with permanent or temporary tattoos and markets herself as liking fast cars and dangerous men who drive them inappropriately, as demonstrated by her 'I Knew You Were Trouble' music video - undeniably and squarely markets to and now fits within the exact consumer demographic to whom Lucky 13 markets and sells its Lucky 13 goods."

The document continues, "In filing this action, tiny Lucky 13 is standing up for itself - much like Ms. Swift has done with great vim and vigor against the bullies she has encountered in her own life."

In the midst of this lawsuit, Taylor Swift has made the all-time revenue record for a single tour by a country artist with the final stats reported from her "Red" tour, according to Billboard.com.

During the course of her "Red" tour, the "Dear John" singer visited arenas and stadiums in four different continents during a 15-month span.

The tour's overall gross of $150 million beats the prior country artist record held by Tim McGraw and Faith Hill.

Taylor Swift began her "Red" tour on March 13, 2013 in Omaha, Neb., with the 24-year-old traveling all around North America, London, Australia, New Zealand, Shanghai and Singapore.
