--- In the United States, under current patent law, the term of patent, provided that maintenance fees are paid on time, is20 years from the filing date of the earliest U.S. or international (PCT) application to which priority is claimed (excluding provisional applications)
Patents are soon expiring. Too soon for any incremental investment in SequestOx. Nasrat gave up further investment, but is maintaining patents for some minimal value in a buyout.
Exclusivity still gives you six years starting from FDA approval, so if somebody were to get sequestox approved they would have at least that long to market the drug as a brand name (+ however long it takes FDA to approve ANDA for first generic)
