Leerink Swann maintains an 'Outperform' on Idenix Pharmaceuticals Inc. (NASDAQ: IDIX).

Analyst, Joshua Schimmer, said, "Gilead (Nasdaq: GILD) (OP-rated) and IDIX are involved in patent interference proceedings initiated by the USPTO which will determine which company invented the disputed genus claim which covers GS-7977. We hosted a conference call with a MEDACorp specialist yesterday to better understand the process and its likely outcome. Based on this call, we believe GILD will likely end up signing a licensing deal resulting in royalties to IDIX..."

"IDIX has a patent application pending ('868) which has a claim that overlaps with one in a patent issued to GILD ('572) which covers GS-7977. IDIX’s application relies on an earlier filing (6/27/03) than GILD (4/21/04) so IDIX is currently the senior party. GILD has an earlier filing date for a provisional patent application (5/30/03) which if deemed the appropriate date, would make GILD the senior party. However IDIX could counter and try to obtain the filing date of 3 additional provisional application dates (5/14/03, 4/28/03, 6/28/02) to leap before GILD and again become the senior party. Post resolution of seniority (which appears to favor IDIX), first-to-invent will be determined; it appears that IDIX has the upper hand for proving this as well."
