Apple has filed for the "Rehearsal Room" that was used in context with the Apple video "Alicia Keys Rehearsal Room' as presented below.

 

Apple's All-New Immersive Entertainment Experiences are designed for Apple Vision Pro, so that users can experience Apple Immersive Video, a remarkable new entertainment format pioneered by Apple. Apple Immersive Video features 180-degree 3D 8K recordings captured with Spatial Audio to transport viewers to the center of a place, moment, or story. The Alicia Key's "Rehearsal Room" was one of four found in Apple's original press release on January 16, 2024.

In Hong Kong, Apple's patent application 306660441 was filed under International Class 041 covering the following

"Entertainment services, namely arranging, organizing, conducting, and presenting augmented reality and virtual reality immersive music concerts, live music performances, music special events; entertainment services, namely, providing augmented reality and virtual reality non-downloadable playback of music in generated playlists via the internet and other communications networks; entertainment services, namely, curating songs for music playlists; compiling and publishing music playlists; production, distribution, and presentation of augmented reality and virtual reality immersive audio and video programs, podcasts, and audio and video augmented reality and virtual reality sound recordings; entertainment services, namely providing ongoing podcasts in the fields of entertainment and music; entertainment services, namely, providing augmented reality and virtual reality non-downloadable music, interviews, live recording sessions, live music performances, and videos featuring musical artists and celebrities."

In the U.S. Apple filed their trademark application 98720437 under the same International Class 041.

It should generally be noted that international trademark classes that Apple files their trademarks under are important as the trademark registration will only protect those classes that have been identified in their original application. In a legal battle, the classes filed for originally could make or break a legal case.
