An attorney representing St. John's University has sent a letter to STJ University regarding their use of the abbreviation "STJ" which is the same as St. John's trademark. St. John's University has multiple campuses and offers online classes, while STJ University only offers online classes and does not have a campus. The letter demands that STJ cease advertising using the STJ abbreviation and clarify they are not affiliated with St. John's University, or else legal action will be pursued for trademark infringement. A response is required within five business days.
