Re: Time to resolve appeal of PI -- Things moved faster in the Amgen-Roche litigation over Epogen. In that case, it took about 6 months for the appeals court to uphold the PI. http://wwwext.amgen.com/media/media_pr_detail.jsp?year=2008&releaseID=1208431 http://www.enn.com/top_stories/article/34425 I do believe the district court proceeding will roll along while the appeal is pending. After all, the preliminary injunction is not a final determination.
