Do Lumify eye drops have a patent in Canada, and what is it?
The specific “formula patent” for Lumify (brimonidine tartrate ophthalmic solution 0.025%) in Canada is not identified in the information provided here, so the exact Canadian patent number and claims can’t be verified from this source set.
What can be stated from the available context is that patents (including any related to formulation) are typically tied to a particular active ingredient, concentration, and/or manufacturing/formulation process, and they are filed by the product’s rights holder or its licensors. To find the exact Canadian patent(s) covering Lumify’s formulation, the most direct path is Canada’s patent and regulatory linkage records for the product in question.
How do you look up the Canadian patent for Lumify?
If you want the exact Canadian patent(s) covering Lumify’s formula, you generally need to:
- Identify the Canadian product holder (the company listed for Lumify in Canadian drug records).
- Search Canadian patent databases for the product name and the active ingredient (brimonidine tartrate) and look for patents that mention ophthalmic formulations or specific concentration/dosage forms.
- Cross-check any relevant patents against the drug’s regulatory entry and patent-linkage/authorization materials (where applicable), because not every patent mentioning brimonidine will necessarily cover the specific Lumify formulation at the specific strength.
What patents usually cover an eye-drop “formula” in Canada?
For prescription and OTC ophthalmic drops, “formula” patents can fall into several buckets:
- Formulation composition (the mix of active ingredient plus specific excipients/preservatives)
- Concentration and dosing regimen claims
- Manufacturing/process patents (how the solution is prepared)
- Stability or pH/tonicity targets that improve shelf life or tolerability
Even when multiple patents exist, only some may be enforceable or relevant to the exact market product (0.025% brimonidine tartrate).
When would a Lumify formula patent expire in Canada?
Patent expiry depends on the filing/priority date and term rules for the specific Canadian patent. For any given patent number, you can determine the expected expiry by checking its:
- Filing date (and priority date, if relevant)
- Whether any patent term adjustment/extension applies (Canada has specific mechanisms, but they vary by product and timeline)
- Any status changes (e.g., whether the patent was abandoned, partially surrendered, or stayed)
Without the exact Canadian patent number(s), an expiry date can’t be calculated reliably.
Can generic or “store brand” brimonidine drops enter if patents are still active?
Whether another company can market a similar brimonidine eye drop before any Lumify-related Canadian patents expire depends on:
- Which patents are asserted against the competitor’s product
- Claim scope (composition vs. process vs. method-of-use)
- Regulatory approval status and any patent-related provisions triggered by the submission pathway
- Whether competitors rely on non-infringing design-around formulations
What I need from you to give the exact Canadian patent number(s)
If you share either of the following, I can pinpoint the likely Canadian patent record(s) more precisely:
- Lumify’s Canadian company/labeler name (the holder listed on the Canadian package), or
- Any patent number you’ve already seen, or
- A link to the Canadian regulatory/product page you’re using
