Mind that the article mentions a Dutch patent from 1598.

I say the big picture is that the steam engine was developed within a legal system that in general protected IP rights, at least respected them on a completely different level than before. Granted there are more pieces to the puzzle, but let's not forge…
High steam pressure isn't just about a wandering ant, but about the major step in the development of the steam engine, opening the technology to all kinds of applications, beyond just pumping.
