In United States v. Liew, --- F.3d ---, No. 14-10367 (9th Cir. 2017), the Court issued a lengthy opinion in a trade secrets case.
The case revolved around Du Pont's technology for producing titanium dioxide.
The Ninth Circuit affirmed the denial of certain jury instructions, reversed a few counts for sufficiency, vacated the sentence, and remanded for consideration of a potential Brady violation.
Of note, a general denial in a civil answer will usually not constitute obstruction of justice.
Also, there is some decent language about the low standard to make a prima facie showing for a Brady violation. The specific issue was about FBI rough notes that allegedly contained exculpatory information.
