I came across these two sentences while reading:
Acme hereby grants Widgetco a license to use the Marks in … .
Acme hereby grants Widgetco the right to use the Marks in … .
There is no additional context. They are two standalone sample sentences. Why does the author use "the" for "right", but "a" for license? My original opinion is that both sentences should use "the", because they are talking about specific things. Doesn't "to use sth" modify the "license" so that it can be identified? My guess is that this has something to do with the nature of a license. You can have several licenses for one right. Right?
