On February 18, 2020. Xspray Pharma (Nasdaq First North Growth Market: XSPRAY) reported that the United States Patent and Trademark Office (USPTO) has granted Xspray three new US patent for HyNap-Dasa (Press release, Xspray, FEB 18, 2020, View Source [SID1234649567]). The new patents, US10,561,643; US 10,561,644; and US10,561,645, are valid until January 2033. This means that Xspray now has seven product patents for the pharmaceutical composition of the company’s primary product candidate, HyNap-Dasa, in the company’s main market USA.
"With a total of seven patents for HyNap-Dasa in our most important market, we can justifiably state that it will be extremely difficult for other players to launch a dasatinib product based on amorphous solid dispersion in the United States during the lifetime of the patent, ie until January 2033. This is undoubtably very important for our potential partners," says Per Andersson, CEO of Xspray.
