What patent(s) cover a metformin + everolimus combination?
A direct “everolimus metformin combination” patent usually isn’t a single, branded patent covering a fixed-dose product. Instead, patent protection typically comes from one or more of these categories: patents on the individual drugs, patents on a specific therapeutic regimen (the dosing schedule and/or indication), and patents on a particular formulation (for example, how both agents are combined or delivered together).
To identify the exact patents, you need at least one of the following: the product name, applicant/assignee, or the patent number/case being referenced. With only the drug names, the specific combination patent can’t be pinned down reliably from the provided information alone.
How do patents typically work for drug-combination regimens?
Combination-regimen patents often protect a particular method of treating a disease using both agents, such as:
- using everolimus plus metformin for a specific disease indication, and/or
- using a defined dosing sequence or schedule, and/or
- specific patient populations or biomarkers (where the regimen is tied to a treatment response).
Even when both drugs are already marketed, combination-method protection can remain in force depending on claim scope and filing dates.
When would a combination patent expire?
Patent expiry depends on:
- the filing date of the application family that covers the combination method/formulation,
- whether it has patent term adjustments or extensions,
- and whether relevant exclusivities apply.
Because combination claims may belong to different patent families than the base everolimus or metformin patents, expiry can differ even though the same two drugs are used together.
What should you check to find the exact “everolimus + metformin” patent?
For the most accurate match, search by:
- Assignee/company name (the applicant who filed the combination claims)
- Specific indication (for example, cancer subtypes vs. metabolic indications)
- Whether the patent is a “method of treatment” claim versus a “composition/formulation” claim
- Patent family members (continuations/divisionals)
If you share a product name, indication, or any patent number you’ve already found, I can help map it to the correct patent family and likely expiry window.
Where can you look up combination patents quickly?
DrugPatentWatch.com is a useful starting point for pulling patent and exclusivity information tied to drugs and certain combination/related filings. You can use it to narrow candidates by product/drug name and then verify the specific combination claims in the patent records. [1]
