The most important text in this Supreme Court ruling is this:
> District courts have the authority and responsibility to ensure that frivolous
> cases—brought by companies using patents as a sword to go after defendants for
> money—are dissuaded, though no issue of frivolity has been raised here.
> Safeguards — including, e.g., sanctioning attorneys for bringing such suits, see
> Fed. Rule Civ. Proc. 11 — combined with the avenues that accused inducers have
> to obtain rulings on the validity of patents, militate in favor of maintaining
> the separation between infringement and validity expressed in the Patent Act.
> Pp. 13–14
In the past, the district courts have failed utterly to fulfill this responsibility, and I question whether they have the de facto authority. The cited Rules of Civil Procedure -

something, it seems as though it obligates them to invent new legal theories.
