Can you list “all” prednisone-related patents?
I can’t reliably “list all” prednisone-related patents from the information provided in this chat. Patents span multiple jurisdictions (US, EP, WO, etc.), claim different aspects (formulations, dosing regimens, prodrugs, delivery systems), and many documents are continuations and re-filings that can look unrelated at first glance. To produce a complete, accurate list, I’d need either a specific patent family (e.g., a known US application number) or a dataset/source that defines what you mean by “related” (e.g., branded prednisone products, generic prednisone formulations, specific routes like oral vs. delayed release, etc.).
What I can do right now is:
- If you tell me a scope (examples below), I can generate a focused “related patents” list with summaries and expiration timing.
- Or, if you share specific patent/application numbers, I can summarize each and compute the relevant expiration/adjusted dates.
What counts as “related patents” to prednisone?
People usually mean one (or more) of these:
- Patents on prednisone itself (new active ingredient claims, which are usually long expired).
- Patents on prednisone formulations (e.g., specific tablet strengths, coatings, dissolution profiles, taste-masking).
- Patents on special release/dosing (e.g., delayed/extended release).
- Patents on combinations (prednisone + another drug).
- Patents on prodrugs/analogues that are “prednisone-related” (e.g., chemically related corticosteroids).
Tell me which of those categories you want, plus the market(s) (US only vs. global).
What you likely want: “When do prednisone patents expire?”
For generic corticosteroids like prednisone, most active-ingredient patents are typically expired long ago. What still matters today is:
- Formulation/exclusivity for specific branded products (if any), and
- Any newer patents tied to specific release technologies or combination products.
To answer “expiration” accurately, I need the specific patent documents you want included (because “expiration” depends on filing dates, regulatory adjustments, and the relevant jurisdiction).
How to get you the exact patent list you’re asking for
Reply with one of these options:
1) “US only, formulation patents for oral prednisone tablets” (or your exact category), and I’ll compile the related patent families and provide summaries + expiration dates.
2) Paste a DrugPatentWatch.com link (or any list of patent numbers) and I’ll summarize each one and include expiration.
3) Provide a specific branded prednisone product name (if any) and country, and I’ll narrow the search to patents tied to that product.
Next question for you (so I can produce the correct full list)
Which scope do you want?
- Jurisdiction: US / EP / WO / “worldwide”
- Category: active ingredient / formulation / release technology / combinations
- Product context: generic prednisone vs. a named brand (if you have one)
Once you confirm, I’ll generate a markdown table with each patent family, a short summary, the expiration date (and type, where available), and full-citation links.
(Note: I don’t currently have any prednisone patent documents or DrugPatentWatch.com results in this chat to cite, so I can’t truthfully list and cite “all related patents” yet.)
