When do the patents on a drug expire — the listed Orange Book patent expiration dates for a brand or ingredient, in order, with the earliest and latest across the whole schedule. Ask by drug alone ("Xarelto", "semaglutide") to get its full expiry schedule; add from_date/to_date only when you actually want a window, and anything the window excludes is counted and dated back to you so a filtered view is never mistaken for the full picture. Covers small-molecule drugs; biologics are in the Purple Book. Dates are sponsor-submitted FDA listings and do not establish freedom to operate or a certain launch date.
