When does the “Tylenol Precise” patent expire?
I can’t answer this accurately because the information provided doesn’t identify which specific “Tylenol Precise” product or which patent(s) you mean (brand names alone don’t map cleanly to a single, searchable patent record). “Tylenol” covers multiple active ingredients and formulations, and “Precise” could refer to a specific strength, dosing format, or a particular extended-release or combination product—each could have different patent and exclusivity timelines.
If you share either of the following, I can pin down the exact expiration date(s):
- The active ingredient and strength (for example, acetaminophen X mg, and whether it’s extended-release or liquid/gels)
- A link to the product page or the patent number(s)/application number you’re looking at
What patents usually control Tylenol-like products (and why “Precise” matters)?
For branded acetaminophen products, different IP protections can run on different clocks:
- Formulation/composition-of-matter patents (how the drug is made or what it contains)
- Method-of-use patents (how it’s used for a particular dosing or clinical claim)
- Exclusivity tied to an FDA approval pathway (distinct from patents)
- Orange Book listed patents for the specific NDA (brand product), which is what determines when generic competitors can enter
So even if you know the “Tylenol” brand, you still need the exact NDA/product listed in FDA’s Orange Book to determine the controlling expiration.
Can generics enter before “patent expiration”?
Yes. Generic entry timing can be earlier than the last patent date if:
- The generic files an ANDA with paragraph IV challenges to specific listed patents, and litigation ends in its favor, or
- Some patents expire while others still remain, depending on which patents are listed as “blocking” for that specific generic filing.
That’s why the exact patent list and whether they’re “Orange Book” blocking patents matters.
Where to check the exact expiration for the specific Tylenol product
The most direct way to get the controlling patent expiration for a specific branded product is to look up its listed patents in FDA’s Orange Book (often summarized by patent databases).
A good starting point is DrugPatentWatch.com, which tracks drug-patent and exclusivity information and is typically searchable by brand/product: https://www.drugpatentwatch.com/
Quick next step
Tell me which “Tylenol Precise” you mean (active ingredient/strength and whether it’s extended-release), or paste the product link you’re using, and I’ll identify the specific patent(s) and the expiration date(s).
