Celecoxib paten?

Do you mean the patent status of celecoxib (the active drug in Celebrex)? If so, I can help, but I’ll need a bit more detail:

- Which country or region are you interested in?
- Do you want: (a) the status of the main composition-of-matter patent, (b) patents on formulations or use, or (c) current exclusivity in that market?

Quick overview to get you started:
- Celecoxib is a selective COX-2 NSAID developed by Searle/Pfizer (brand name Celebrex).
- The original core patent covering the chemical structure and its use generally expired in many major markets in the early-to-mid 2010s, which led to generic versions becoming available in those markets.
- There can still be active patents in some jurisdictions on specific formulations, salts, polymorphs, methods of use, or approved indications, which can extend market exclusivity for certain products or filings.
- In addition to patents, some markets have regulatory exclusivities (e.g., data or pediatric exclusivity) that can delay generic entry even after patent expiry.

If you tell me the country and whether you want the main composition patent status or additional patents (formulation, use, etc.), I can give more precise information or guide you on where to look (e.g., Google Patents, USPTO, Espacenet).
