Cardax has obtained and is continuing to seek patent protection for compositions of matter, pharmaceutical compositions, and pharmaceutical uses, in certain disease areas, of our various carotenoid analogs and derivatives.
Such carotenoids include astaxanthin, zeaxanthin, lutein, and/or lycophyll, and esters and other analogs and derivatives of these compounds. More specifically, we seek to protect: (i) the composition of matter of novel carotenoid analogs and derivatives, (ii) pharmaceutical compositions comprising synthetic or natural preparations of novel or natural occurring carotenoid analogs and derivatives, and (iii) the pharmaceutical use of synthetic preparations of novel or naturally occurring carotenoid analogs and derivatives in specific disease areas, including, but not limited to, the treatment of inflammation and related tissue damage, liver disease, and reperfusion injury, as well as the pharmaceutical use of synthetic or natural preparations of novel or natural occurring carotenoid analogs and derivatives for the reduction of platelet aggregation. We intend to enforce and defend our intellectual property rights consistent with our strategic business objectives.
We have 29 issued patents and one pending patent related to the composition of matter, pharmaceutical compositions, and pharmaceutical uses of our drug candidates as well as many other related molecules that will expire between 2023 and 2028, subject to patent term extensions. We also have filed additional patents to extend patent coverage in the U.S. and worldwide to 2039-2040, with such applications including coverage related to certain cardiovascular uses on the basis of the CHASE clinical trial results as well as coverage related to the composition of matter of CDX-101.
