I remember a similar trademark-based scheme being proposed several
years ago, and as I remember it the conclusion was that trademark law
could not be used to prevent interoperability.  For example, Apple
couldn't prevent you ataching non-apple drives to Macs by making the
connector pins be a trademarked apple shape.

I don't remember whether copyright was considered.
