Following Apple’s shift to California-themed names for its Mac operating systems with OS X Mavericks back in 2013, Apple appeared to take steps to protect a number of other California-related names by filing for trademarks under a series of shell companies intended to mask the true identity of the applicant.
All told, we identified 19 trademarks that were applied for under six different companies that all appeared to be Apple shell companies. Several of these names, including Yosemite, Sierra, and Mojave, have been used by Apple, while others have yet to be put to use.
Over the years, the trademark review process has played out for all of these applications, with most being subject to some form of back-and-forth between the applicants and examiners involving various approvals, denials, and suspensions. Even for approvals, however, owners are required to submit proof of the trademarks being used in commerce. This Statement of Use can be submitted up to 36 months after trademark approval, as long as the applicant regularly requests successive 6-month extensions to the original 6-month submission period.
With over five years having passed since the trademarks were applied for, many have now been abandoned, either at some point during the review process or through failure to provide proof of commercial use following approval. In fact, of the original 19 names that were included in the trademark applications, all but four of them have been either used by Apple or abandoned, with the remaining live applications being Mammoth, Monterey, Rincon, and Skyline.
