One letter used as the Worcester Red Sox logo could draw legal action over trademark infringement.

When the WooSox released their logos and mascot during an event in Worcester Monday.

A baseball team in Cape Cod was watching and within 48 hours of introducing the logo, team representatives from the Wareham Gatemen reached out to the Worcester Red Sox.

The team’s concern: the WooSox’s alternate logo and the style of the "W".

The Wareham Gateman, a college summer baseball team in the Cape Cod League, contacted the Worcester Red Sox Wednesday morning to alert the organization that one of the "W" logos appears to infringe upon their logo.

“We have to enforce the trademark because if you don’t, you could potentially lose it. But hopefully we can try to work it out.” Gatemen Sr. Vice President Glen Hannington said.

Hannington said while he reached out to the WooSox, he didn’t speak with anyone and left a message.

The potential infringement pertains to the "W" that mimics the font used by the Boston Red Sox and Pawtucket Red Sox. The Wareham Gatemen received trademark rights for a "W" with that font in 2014, according to the United States Patent and Trademark Office.

The Wareham Gatemen filed a trademark with the United States Patent and Trademark Office.

Hannington hopes the matter doesn’t have to go to court, but didn’t rule anything out.

“We’d have to sit down and discuss a few things,” Hannington said. “I can’t disclose, but that would be my hope. And if it doesn’t, then we’ll have to follow the alternative route.”

The Worcester Red Sox didn’t immediately return a request for comment.

On Monday, the Worcester Red Sox opened a pop-up story selling merchandise with the "W" similar to the Gatemen "W".

“We don’t have any problem with some of their merchandise, the loop 'W' and a few others,” Hannington said. “But for the purpose of some of these stand alone hats and shirts with the 'W', we feel like that’s our ‘W'.”

The "W" in question is listed as an alternate cap by the Worcester Red Sox. The team’s primary "W" logo wraps into a heart in the center. It’s the same "W" that appears at the top of the WooSox new website.

Hannington took no issue with that logo.

The WooSox logo in question first appeared on Hannington’s radar three weeks ago in Florida. He approached a woman wearing a baseball cap with "W" in the font of the Boston Red Sox.

“I see that distinct 'W'. It’s just like the distinct 'B' for the Red Sox. That script,” Hannington said. “I said, ‘Oh Wareham Gatemen.’ She says to me, ‘No, the WooSox.’”

Hannington snapped a picture of the cap and brought it up with the board of the Wareham Gatemen just to make them aware of the unlicensed merchandise. After Monday’s announcement, the organization felt they need to contact the WooSox.

“They unveiled everything this week. That just affirmed it and people got a slow burn on the board and they felt it wasn’t right,” Hannington said. “We had that 'W’ for over 30 years.”
