Just a point - the term "oyster" can be used in any other industry or undertaking in categories that Rolex hasn't registered the trademark for. So a pizza shop using the term or a sportswear company using the term wouldn't attract Rolex's ire or give them a case against that business, because they are not competing in the range of products. What brought Oyster & Pop to Rolex's attention is the fact that it's a clock, which is close enough to Rolex's business that they need to care. Usually, you don't license out trademarks. First, it dilutes your brand, because you didn't care for it enough that you traded it like a commodity and second, a trademark is meant to be your distinct mark(s) in your industry to distinguish you from all others.
