What is the registration number for the 'DELTA HOTELS' trademark of Delta Hotels By Marriott?

According to Delta Hotels By Marriott's 2025 Franchise Disclosure Document, the trademark 'DELTA HOTELS' is registered with the United States Patent and Trademark Office under registration number 4722193. The registration was effective as of April 21, 2015. Delta Hotels By Marriott also has several other registered trademarks, including 'DELTA HOTELS & OPEN D DESIGN,' 'DELTA HOTELS MARRIOTT & OPEN D DESIGN,' and 'DELTA HOTELS BY MARRIOTT.'

It is important to note that Delta Air Lines, Inc. has filed proceedings to cancel some of Marriott's registrations, including registration numbers 5955787, 5955788 and 5955797, and to oppose registration of trademark application Serial Nos. 88853111 and 88853112. These actions are currently suspended pending the outcome of federal litigation between Delta Air Lines, Inc. and Marriott International, Inc. This ongoing legal dispute could potentially impact the use of these trademarks in the future.

Delta Hotels By Marriott also states that they do not have a federal registration for some of their principal trademarks. Therefore, those trademarks do not have as many legal benefits and rights as federally registered trademarks. If their right to use a trademark is challenged, a franchisee may have to change to an alternative trademark, which may increase their expenses. However, once they obtain a federal registration, their rights derived from federal registration of the trademark will be effective as of the filing date of the application.

As a Delta Hotels By Marriott franchisee, you are required to use the name designated by the company for your hotel, and this name may be changed at their discretion. You are also prohibited from using the words 'Delta Hotels,' 'Delta Residences,' 'Delta,' or 'Marriott,' or any other trademark or confusingly similar mark or name in your corporate, partnership, or trade name, or in any other business or trade name, or otherwise in connection with any business activity or venture. You are also prohibited from using their trademarks or any confusingly similar trademarks in any email address, domain name, mobile application name, or any other electronic identifier.
