National Wine School LLC has been named as a defendant in a federal trademark case filed by PhillyWine LLC in the U.S. District Court for the Eastern District of Pennsylvania. The case is captioned PhillyWine LLC v. KSWCO LLC et al., Case No. 2:26-cv-01268-JDW.
Because the lawsuit has raised public questions about wine education, credentialing, naming rights, and the relationship between local wine schools in Philadelphia, National Wine School is providing this statement for students, alumni, instructors, partner schools, employers, journalists, and members of the wine trade.
Overview
The dispute centers on alleged rights in the phrase “Philly Wine School.” KSWCO LLC, the entity associated with the Wine School of Philadelphia, owns U.S. Registration No. 8,055,977 for PHILLY WINE SCHOOL in connection with wine-education services. PhillyWine LLC has challenged that registration and has sought to restrict use of the phrase while the lawsuit proceeds.
The lawsuit does not change National Wine School’s educational programs, student records, credential verification, or ongoing operations.
National Wine School disputes the allegations made against it and related defendants. Those allegations remain allegations. The court has not made a final ruling on all claims in the case.
Current Court Status
On May 26, 2026, Judge Joshua D. Wolson denied PhillyWine LLC’s motion for a preliminary injunction.
A preliminary injunction is an emergency form of relief requested before a full trial or final judgment. PhillyWine asked the court to restrict the defendants’ use of “Philly Wine School” while the lawsuit continued. The court declined to do so.
According to the court’s May 26 memorandum, PhillyWine had not made the required showing that it was likely to prevail on its claim to senior rights in “Philly Wine School.” The court also stated that, on the record before it, PhillyWine and its predecessor had used the term only sporadically until recent years, while the Wine School of Philadelphia had used the term for close to a decade.
The court also noted that PhillyWine’s examples of alleged confusion arose in late 2025, when PhillyWine began using “Philly Wine School” more directly in outward-facing branding. The court stated that the record contained no evidence of confusion during the earlier period when PhillyWine operated under the “PhillyWine” name while the Wine School of Philadelphia used “Philly Wine School” or similar phrasing in the marketplace.
The case may continue, and the denial of a preliminary injunction is not a final judgment on every issue. However, the ruling is an important public development in the case.
Students and Alumni
National Wine School programs continue to operate.
Student records, completed coursework, examinations, transcripts, certificates, pins, and credential-verification services remain active and unaffected by the preliminary-injunction ruling.
No court order has required National Wine School to suspend programs, withdraw certifications, change student records, or stop recognizing credentials previously issued through National Wine School.
Students and alumni who need credential verification may continue to use National Wine School’s usual verification channels.
Partner Schools, Instructors, and Employers
National Wine School remains focused on transparent, U.S.-based wine education and credentialing.
The lawsuit does not change National Wine School’s academic framework, instructor training, curriculum standards, examination procedures, or credential-verification process.

Clarifying the Naming Issue
This case has sometimes been described as a dispute involving “PhillyWine.” That description can be misleading.
National Wine School understands the central naming issue to involve the phrase “Philly Wine School.” The Wine School of Philadelphia has long been known informally by that name. PhillyWine LLC operates a separate WSET-aligned business with a different ownership history than the Wine School of Philadelphia.
Those are different identifiers with different histories.
National Wine School does not object to PhillyWine operating as PhillyWine. The dispute concerns whether PhillyWine may claim superior rights in “Philly Wine School” and use that phrase in a way that creates confusion with the Wine School of Philadelphia.
Why Credentialing Matters
The lawsuit has also raised broader questions about wine credentials in the United States. National Wine School welcomes that discussion.
Wine education in the United States is not controlled by a single credentialing body. Students, employers, schools, and instructors rely on a range of private certification systems, each with its own structure, standards, curriculum, examinations, and method of verification.
National Wine School was built for that American credentialing environment. Its programs are designed around structured levels of study, published learning expectations, assessment, records, certificate verification, and continuing professional relevance. The goal is to provide a transparent U.S.-based pathway for students and professionals who want serious wine education outside a single-provider framework.
That independence is central to National Wine School’s identity.
National Wine School is based in Vermont and operates as a vocational-training institution offering wine-trade certifications. Its structure is different from WSET’s Approved Programme Provider model. WSET describes itself as a U.K. awarding organization whose qualifications are delivered through third-party Approved Programme Providers around the world. WSET also states that its qualifications do not form part of any regulated qualifications framework outside the U.K.
In our view, the future of American wine education should include more transparency, more accessible professional pathways, and more than one legitimate route into the trade. Students should understand what credential they are pursuing, who issues it, how it is assessed, how it can be verified, and what educational model stands behind it.
That is the conversation National Wine School intends to keep having — clearly, publicly, and on the record.
National Wine School’s Position
National Wine School believes this lawsuit should be understood in its proper context: a dispute involving naming rights, institutional identity, and competition within the wine-education market.
The Wine School of Philadelphia was founded in 2001 as an independent wine-education institution. National Wine School represents an independent credentialing model developed for the U.S. wine trade. It is not a WSET Approved Programme Provider and does not claim to be one.
That distinction matters. Wine education in the United States includes multiple private credentialing systems, curriculum providers, schools, instructors, and assessment models. National Wine School’s position is that students and employers benefit from clear distinctions among those systems.
National Wine School will continue to defend its programs, its institutional reputation, and the validity of its educational work. It will also continue to explain why independent, transparent, U.S.-based wine credentialing is important for students, working professionals, employers, and the future of wine education.
