WASHINGTON –As the 2023 World Series presented by Capital One gets underway this week, fans are heading to Phoenix and Dallas to support their favorite teams and purchase officially licensed gear and memorabilia. With high demand for merchandise during this year’s World Series, the National Intellectual Property Rights Coordination Center (IPR Center), including Homeland Security Investigations (HSI) and U.S. Customs and Border Protection (CBP), joins MLB in cautioning fans to be on the lookout – both online and offline - for counterfeiters attempting to sell unauthorized, knock-off products and tickets.
