Hi. I am wondering: why is "the" not used when expressing number units. e.g.
Cited Invention 1 and Cited invention 2 are not related.
We don't use "the", why? Because the number is a modifier of the noun?
However: The cited inventions are similar. (We use the to express the plural inventions.)
The numbers 1 and 2 tells us which inventions, and so 'the' isn't required--the inventions are already specified. But they aren't here, The cited inventions are similar which is why 'the' is used.
