Stock Market Reactions to Patent Litigation -- can you help?

I have had a request from Nam Nguyen (TU Darmstadt, Germany) who is currently writing a Bachelor Thesis on the topic "Stock Market Reactions to Patent Litigation".

Nam already knows of the information available from an 18 September 2013 blogpost on PatLit, "Patent litigation and stock market reactions: evidence from a recent study" -- but Nam wonders what further information on this subject can be recommended. Readers -- it's up to you!
