My university's library just received a copy of a newly published book by Johann Pitz, Atsushi Kawada, and Jeffrey A. Schwab titled Patent Litigation in Germany, Japan and the United States: A Practitioner's Guide (C.H. Beck/Hart/Nomos 2015). Here is a link to further information, and here is the book description:
This book gives a systematic comparative overview of the characteristic principles of patent enforcement proceedings in the US, Japan, and Germany, i.e. the major jurisdictions where patent holders might seek for legal remedies in parallel proceedings. The book examines topics such as: survey matter of infringement, claims of the patent holder and objections of the infringer, pre-procedural measures, infringement proceedings, and procedural principles. It will be of interest to practitioners working in the field of copyright, patent, and trademark law.
From my very quick perusal, I'd say this looks like it could be a useful resource. Part 4 (pages 51-67) discusses injunctions and damages in the three countries, and Part 5 (pages 110-21) discusses "pre-procedural measures" such as preliminary injunctions and declaratory judgments.
