Amarin Corp Plc (AMRN)

Marjac, here is what I dug out.

Among the six invalidated patents, I found a couple of articles discussing the initial PTO rejection or action. SeekingAlpha one has some detailed analysis on '727 and mentioned a response to "Non-Final Office Action" for '715. '727 was submitted together with '728, and granted together on the same date. I included it here even though it is not invalidated.

Admit that I haven't read the patents and analysis in detail.

FYI, another patent that was rejected and dragged on quite a while before finally granted is the 8,188,146 which carves out the 250-1000mg gelatin capsule of >95% EPA. The reason of rejection wasn't made clear but one article mentioned "Amarin's application was in conflict with another patent that was issued to Mochida, a Japanese drug firm, for its fish-oil drug Epadel". It's always been a mystery to me that Amarin can patent Vascepa after Mochida, but devils can be in the details.
