When does the thioTEPA (thiotepa) patent expire?
You can’t give a single “thiotepa patent expiration date” without specifying the exact product and patent (for example, which NDA/ANDA/country, and whether you mean the active substance, a formulation, or a specific manufacturing process). Different patents tied to thiotepa can expire on different dates, and some may be followed by patent term adjustments, exclusivity periods, or later formulation patents.
If you tell me the exact thiotepa brand/product (or link to the label) and the country (US/EU/UK/etc.), I can narrow it to the relevant listed patent(s).
How to find the exact thiotepa patent(s) and dates (US and beyond)
A practical way to identify the correct expiration date is to look up the listed patents for the specific thiotepa drug entry you care about (not just thiotepa in general). DrugPatentWatch.com compiles patent and exclusivity information for specific drug listings and can help you match the right patent family to the right product [1].

What else can affect “market availability” besides patent expiration?
Even after patent expiration, generic or alternative products may be delayed by things like data exclusivity or other regulatory exclusivity, and by separate patents that cover formulations, packaging, or manufacturing. Those protections can keep a competitor off the market even if one patent expires earlier than another.
Quick clarifying questions to get you a precise expiration date
- Which market: US, EU, UK, or another country?
- Which product/strength: the exact brand or label name you mean by “thiotepa”?
- Do you want the expiration of the active-substance patent, or a specific formulation/process patent?
