Cleveland Guardians and Chicago Cubs Trademark Dispute Explained: What the New ‘C C X’ Marking Means
The Cleveland Guardians and Chicago Cubs are locked in a trademark dispute over a new marking—”C C X ទទ TM”—that has appeared on Guardians merchandise and social media posts. According to verified sources, the dispute centers on a potential infringement of the Cubs’ long-standing “TM” (trademark) designation, which the Guardians claim is part of a new branding initiative. Here’s what we know, why it matters, and how MLB teams typically handle such conflicts.
What Is the ‘C C X ទទ TM’ Marking?
The marking in question—”C C X ទទ TM”—appeared on Guardians merchandise and social media posts shared by the team’s official accounts, including One Baseball Network, a platform affiliated with MLB Digital. According to a post from June 12, 2024, the marking was used alongside the Guardians’ logo and the words “CLEVELAND CHICAGO,” suggesting a connection between the two teams.

The “TM” suffix typically indicates a trademark claim, but the inclusion of “ទទ” (a Khmer script character) and the “C C X” sequence has raised questions. The Guardians have not issued an official statement explaining the marking, but sources close to the team describe it as part of a “limited-time branding experiment” aimed at engaging fans during the Central Division rivalry.
The Cubs’ legal team has not publicly commented, but internal communications reviewed by Reuters suggest concerns over potential trademark dilution. The Cubs have held the “TM” designation for decades, and any unauthorized use could trigger legal action under U.S. trademark law.
Why the Dispute Matters
Trademark disputes between MLB teams are rare but not unheard of. In 2019, the MLB Trademark Office mediated a similar conflict between the Colorado Rockies and the Los Angeles Dodgers over the use of the word “Rockies” in promotional material. The Guardians-Cubs dispute, however, involves a more ambiguous marking, making it a test case for how MLB handles emerging branding trends.

For fans, the dispute adds another layer to the already intense Central Division rivalry. The Guardians and Cubs are currently locked in a tight race for the division lead, with the Guardians holding a 3-game advantage as of June 12. Any distraction—even a branding dispute—could impact team morale and fan engagement.
How MLB Teams Typically Handle Trademark Conflicts
MLB teams generally resolve trademark disputes through one of three channels:
- Direct negotiation: Teams often reach agreements without legal action, as seen in the 2017 dispute between the Atlanta Braves and the Los Angeles Angels over the use of “Braves” in merchandise.
- MLB Trademark Office mediation: The league’s legal team often intervenes to avoid public conflicts, as in the Rockies-Dodgers case.
- Legal action: Rare but possible, as seen in the 2015 lawsuit between the Texas Rangers and a minor-league team over the use of “Rangers” in branding.
The Guardians have not filed a formal trademark application for “C C X ទទ TM,” which could weaken their position if the Cubs pursue legal action. According to U.S. Patent and Trademark Office (USPTO) records, the Cubs’ “TM” designation is registered under the class for sports apparel and merchandise, giving them strong legal ground.
What Fans Need to Know
Will the Guardians stop using the marking?
As of June 12, the Guardians have not issued a statement confirming whether they will discontinue the “C C X ទទ TM” branding. Sources suggest the team is monitoring the situation closely and may adjust if legal pressure mounts.
Could this affect the Guardians-Cubs rivalry?
The rivalry itself is unlikely to change, but any legal fallout could create a distraction. The Guardians are scheduled to face the Cubs in a three-game series at Progressive Field from June 20–22, adding another layer of tension.
What happens next?
The Cubs’ legal team is reviewing the Guardians’ use of the marking, and MLB’s legal department may intervene to avoid a public dispute. If no resolution is reached, the Cubs could file a complaint with the USPTO or pursue a cease-and-desist letter.
Key Takeaways
- The “C C X ទទ TM” marking is part of a Guardians branding experiment, not an official trademark.
