negative limitation

On the other hand, I am completely opposed to Amendment No 6 tabled by Mr Teverson. This would introduce an excessively negative limitation, which would prove too much of a burden for subsequent fishing agreements.

By extension, a disclaimer may also mean the action of introduction a negative limitation in a claim, i.e. "an amendment to a claim resulting in the incorporation therein of a "negative" technical feature, typically excluding from a general feature specific embodiments or areas".
