`orange_book_patent_expirations`

Pack: fda-drug-competition · Endpoint: https://gateway.pipeworx.io/fda-drug-competition/mcp

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.

Parameters

Name	Type	Required	Description
`drug`	string	no	Ingredient, trade name, or applicant, e.g. “Xarelto” or “rivaroxaban”.
`from_date`	string	no	Optional window start YYYY-MM-DD. Omit for the drug’s whole schedule.
`to_date`	string	no	Optional window end YYYY-MM-DD. Omit for the drug’s whole schedule.
`limit`	number	no	Results (1-100, default 25).
