Arizona Diamondbacks Trademarks

The Arizona Diamondbacks – sometimes referred to as the D-backs – are a Phoenix-based professional baseball team. The Diamondbacks competed in Major League Baseball (MLB) as a member club of the National League (NL) West division. (Read more on MLB trademarks.)

The Diamondbacks are one of the newest teams in the MLB, having been created as an expansion franchise, along with the Tampa Bay Devil Rays, and joined the league in 1998. The Diamondbacks play their home games at Chase Field, formerly known as Bank One Ballpark. 

Since the team’s creation, the Diamondbacks have won five NL West division titles, one NL pennant, one Wild Card game, and the 2001 World Series, in which they beat the New York Yankees and became the fastest expansion team in major league history to win the World Series. This also made the Diamondbacks the only major professional sports team in Arizona to win a championship. 

The Diamondbacks have three players listed in the National Baseball Hall of Fame; Randy Johnson, Alan Trammell, and Roberto Alomar. 

Famous Arizona Diamondback trademarks 

Over the last 20+ years, the Arizona Diamondbacks have built their brand as a recognizable and prominent team within the MLB. As a result, they have registered over 30 trademarks (and counting) to protect their brand reputation and intellectual property. All trademarks are registered by AZPB Limited Partnership 

The single “A” logo

The Arizona Diamondbacks are obvious by their team logo, which is made up of the letter “A” with a snake’s tongue as a crossbar, and the logo stylized in italics. This was inspired by the Western Diamondback Rattlesnake, a species of snake that is found in Arizona. 

The team logo has seen a number of variations, including the addition and removal of the team name stylized alongside the “A”, but the italic letter has always been a constant in the team logo history. The filed trademarks also disclose that the illustration also includes where a drawing or design may include words, letters, and numbers alongside the logo.

  • Entertainment services in the nature of baseball exhibitions

Wrapping up

With over 30 trademarks and growing, from their team name, logos, and other commercial and charitable opportunities relating to the team, all trademarks are significant to the brand of the Arizona Diamondbacks.
