It's just that we have little reason to believe in inventing at all. By 2150, mankind should have other means of access to standard Trek technology. And most of it would have been invented 2150 BC, not AD 2150. Cochrane should have been the very last human inventor, really.
I doubt anything much was invented or even reverse-engineered during ENT, as the result of discoveries made by Archer or his peers. Although stuff may have been purchased or otherwise acquired aplenty: the Vissians of "Cogenitor" might have donated photon torpedo blueprints, say, now that Earth already knew what to ask for.
