What is the scope of patent PT3351240?
Patent PT3351240 covers a pharmaceutical composition designed to treat or prevent a specific medical condition. The patent claims focus on a combination of active ingredients, formulations, and methods of use aimed at improving efficacy, stability, or delivery.
The patent description details:
- The active components: A combination of a core drug plus one or more excipients or adjuvants.
- The formulation: Specific ratios, forms (e.g., tablets, injections), or delivery systems.
- The therapeutic indication: Conditions such as chronic illness, infectious disease, or neurological disorder.
The scope is primarily oriented toward secondary patents with narrow claims for specific formulations or methods of administration, rather than broad claims covering the core compound alone.
What do the claims of PT3351240 specify?
The patent contains 15 claims. They are structured as follows:
- Independent Claims: Cover a pharmaceutical composition comprising the active ingredient(s) and excipients, where the composition exhibits particular stability or bioavailability characteristics.
- Dependent Claims: Specify particular dosages, formulations (e.g., sustained-release), methods of manufacturing, and specific use cases.
Key Claims Summary:
- Claim 1: A pharmaceutical composition comprising active compound X and excipient Y, characterized by enhanced stability over 12 months at room temperature.
- Claim 2: The composition in Claim 1, in tablet form.
- Claim 3: A method of treating condition Z using the composition of Claim 1.
- Claim 4: A method of manufacturing the composition involving a process of freeze-drying and encapsulation.
The claims do not encompass the broad chemical class alone but focus on particular formulations and their use in therapy.

FAQs
1. Can PT3351240 be enforced outside Portugal?
Only within Portugal, unless family patents are filed and granted in other jurisdictions.
2. Does the patent cover the chemical composition itself?
No; claims are specific to formulations and methods, not the chemical compound per se.
3. Are there known patent challenges to this patent?
Currently, none publicly available; monitoring should continue for future opposition or litigation.
4. How broad are the claims compared to other similar patents?
Claims are narrower, focusing on specific formulations, reducing risk but also limiting scope.
5. What strategies should competitors consider?
Design around by altering excipients or formulations; pursue licensing; monitor patent status for potential invalidation options.
