Sorry JJS but you are not correct here.

You do buy the rights to a vendor ID. Once you have paid your $1500 it is
yours for ever, they do not take it back.

The annual fee you refer to is the license to say that your product conforms
to the USB standard and has been tested to be so. You also have to submit
each product for testing to be able to claim this. Once you have done both
these, license fee + testing, your product will be listed as being compliant
to the USB spec.
If you do not have both these things you are not permitted to advertise or
use the USB compliance logo. However, your vendor ID is still valid and
recognized.

As for the PID (product ID), it is manufacturer specific and should
controlled by the owner of the used vendor ID. It is not controlled by the
USB Implementers Forum.
