It's uncommon to see the Court dismiss an ANDA case before trial. The patents are usually grounded enough to avoid easy 101 issues, infringement is as likely to be conceded as disputed, and any other serious invalidity contentions are normally simply reserved for trial (none of our Delaware judges allow for SJ motions in ANDA cases without leave).

That being the case, Judge Stark's dismissal of the complaint in Almirall, LLC v. Torrent Pharmaceuticals Ltd., C.A No. 20-1373-LPS, D.I. 50 (D. Del.

The Court held a five-day bench trial in Biogen Int'l GmbH v. Amneal Pharms. LLC, C.A. No 17-823-MN in December 2019, dealing with a host on invalidity issues, including obviousness, enablement, and written description.
