The article discusses a legal case between Delta Air Lines and Ontro Ltd regarding trademark opposition. The main focus is on whether the term "SKYCLUB" can be used by both parties without causing confusion. The court examined various services offered by the companies, such as air transportation, in-flight magazines, loyalty schemes, chauffeur services, luggage storage, and meal arrangements for travelers. The key question was whether these services are similar enough to potentially confuse customers.
