In the United States at least, ™ doesn't mean "pending" per se — you can use ™ even when you have a registered mark, and marks do not need* to be registered to be valid:
> Is registration of my mark required?
> No. You can establish rights in a mark based on legitimate use of the mark.
*: Some countries operate under a first-to-file system, and unregistered trademarks may be at risk even for US-based businesses that operate internationally.
