  • I know that to many investors yesterday’s district court AMRN ruling seems unfair. And for those of us that own AMRN, it was painful. The judge relied in part on the fact that the advantage of EPA over HDA of reducing TGs but not increasing LDL-C was disclosed in the Mori 2000 reference (, and re: secondary factors, the REDUCE-IT trial was not directed at people with TG levels recited in the asserted patent claims. The judge supported her ruling with a 70 page opinion. Given the facts and law, her ruling was not ridiculous.
    However, the battle is not over. I provide biopharma investors insight into the significance of this ruling and the future of this lawsuit (e.g standard of review by the appellate court and time frames) in my post at the link below. I am founder of Amp, and an experienced biotech PhD patent lawyer and biopharma analysist/investor who reviewed the 70 pg DC judge’s opinion in the $AMRN ANDA #Vascepa case.
