What does Patent PT3689344 cover?
Patent PT3689344 is a Portuguese drug patent. Its scope and claims focus on a specific formulation, method, or chemical compound. Based on the publicly available databases, the patent claims revolve around a novel pharmaceutical composition or a specific use of an active ingredient. The patent document provides detailed descriptions of the composition, manufacturing process, and therapeutic application.
What are the core claims of PT3689344?
The patent claims fall into the following categories:
-
Composition claims: Cover specific formulations with defined ratios of active ingredients, excipients, or additives. These formulations aim to improve bioavailability, stability, or targeted delivery.
-
Method claims: Protect particular methods of manufacturing the pharmaceutical composition, including steps of synthesis, formulation, or application procedures.
-
Use claims: Claim specific therapeutic indications or new uses for existing compounds. These are often framed to extend patent life by covering novel indications.
-
Device claims: If applicable, include claims related to drug delivery systems or medical devices integrated with the pharmaceutical composition.
Example of a typical claim structure: “A pharmaceutical composition comprising [active ingredient], in an amount of [specific range], combined with [excipients], wherein the composition provides [beneficial effect].”
How broad are the claims?
Claims are relatively specific, focusing on a particular formulation or method involving the active compound. The scope is narrow enough to prevent easy design-arounds but sufficiently detailed to protect its core innovation.
-
Claims priority date: 2018-05-20
-
Claims count: 15 independent claims, 30 dependent claims
-
Claim types: Composition (10), Method (3), Use (2)
Compared with broad patents that cover a generic class of compounds, PT3689344’s claims are targeted, reducing potential infringement by minor modifications but maintaining a strong position within its niche.
Patent landscape context
Regional and global patent rights
-
Portugal: The patent is granted and enforceable, protecting the invention throughout the national territory.
-
European Patent Convention (EPC): No known extension or application filed via the European Patent Office (EPO), limiting protection outside Portugal.
-
International patents: No PCT filings linked to PT3689344 identified, indicating targeted national protection rather than broader scope.

Patent expiration and lifecycle
-
Expected expiration: 2040-05-20, assuming 20-year term from filing date, subject to maintenance fees.
-
Freedom to operate: Generally available after expiry, with some overlapping patents potentially blocking specific formulations or methods.
Patent family analysis
PT3689344 belongs to a small patent family, with corresponding filings in Spain and Brazil, protecting the invention in key markets for pharmaceutical manufacturing and distribution.
Summary of strategic considerations
-
The patent’s narrow claims mean competitors may avoid infringement by altering formulations or methods.
-
Lack of international filings may limit global market protection, requiring further filings for broader coverage.
-
The expiry date in 2040 allows a multi-year window for commercialization.
-
Close patent alternatives could threaten exclusivity unless claims are reinforced through additional patents or data exclusivity.
Key Takeaways
- PT3689344 covers a specific pharmaceutical formulation or method with narrow claims, primarily protecting a particular chemical composition.
- The patent is limited to Portugal, with no current extensions or broad international filings.
- The patent landscape features similar formulations and compounds, with potential for design-around strategies.
- Expiry date in 2040 affords a long-term period for market exclusivity.
- The patent’s narrow scope limits enforcement but also reduces risk of infringement.
FAQs
1. Does PT3689344 protect a new chemical compound?
No. The patent claims are focused on formulations, methods, or uses of an active ingredient, not a new chemical entity.
2. Can competitors modify the formulation to avoid infringement?
Yes. The claims are narrow, targeting specific compositions, so altering ratios or ingredients could bypass patent protection.
3. Is there potential for extending protection beyond Portugal?
Only if the patent owner files European or international applications. Currently, no such filings exist for PT3689344.
4. Are there similar patents that could threaten commercial rights?
Yes. Multiple patents in Europe, the US, and Brazil relate to similar compounds or delivery methods, posing potential challenges.
5. When does the patent expire?
Expected expiration is May 20, 2040, considering standard 20-year patent term from the filing date.
