What is the scope of WO2013190582?
WO2013190582 relates to a pharmaceutical invention with a focus on specific drug formulations, delivery methods, or therapeutic applications. The patent claims cover compositions, their preparation methods, and potentially their use in treating certain diseases. Precise scope depends on the claims granted and their wording, which include:
- Composition claims encompassing specific active pharmaceutical ingredients (APIs), possibly combined with carriers or excipients.
- Method claims describing manufacturing processes or administration protocols.
- Use claims for treating particular medical conditions.
The patent aims to secure exclusivity over a particular formulation or therapeutic indication, with claims possibly spanning from broad composition claims to narrower use-specific claims.
What do the claims specify?
Based on the typical structure of WIPO applications of similar scope, WO2013190582 likely includes:
- Independent claims that define the drug composition by the combination of specific APIs, their concentrations, and delivery forms.
- Dependent claims that specify particular variations, such as formulations with a certain excipient or specific dosing regimens.
- Use claims emphasizing treatment of targeted diseases, such as inflammatory conditions, neurological disorders, or cancers.
The claims' breadth or narrowness depends on whether they encompass general classes of compounds or are limited to specific chemical structures or formulations.
How broad are the claims?
- If the claims cover a broad class of compounds or delivery methods, scope encompasses multiple drug candidates or formulations, increasing patent strength and market exclusivity.
- Narrow claims restrict protection to specific compounds or formulations, limiting competition but offering less market scope.
The patent's enforceability and commercial value largely depend on claim scope, with broad claims providing stronger market barriers if granted.
Patent landscape overview
Publication details
- Publication date: December 26, 2013
- Applicant/Inventor: The application originated under WIPO's PCT system, with applicant identities possibly reflecting a pharmaceutical company or research institution.
- Priority data: Applications often list priority claims from earlier filings, affecting patent term and global patent strategy.
Relevant patent classifications
Patents related to this application often fall within the following classifications:
- C07D (Heterocyclic compounds)
- A61K (Medicinal preparations)
- A61P (Therapeutic activity of chemical compounds)
Patent family and territorial filings
- WO2013190582 is a PCT publication, enabling national phase entries in multiple jurisdictions.
- Patent families usually include filings in key markets: US, Europe, Japan, China, and others.
- Patentability, validity, and enforceability vary across jurisdictions, influenced by local patent laws and prior art.
Competitive landscape
The patent landscape includes:
- Similar patents claiming compound classes or delivery methods.
- Patent families filed by competitors or academia developing alternative formulations.
- Patent expiration timelines estimated around 2033-2034, based on PCT filing date and patent term length.
Landscape strategies
- Filing additional patents for derivatives or combination therapies.
- Maintaining broad claims through divisional or continuation applications.
- Licensing or cross-licensing to overcome validity challenges.
Key legal considerations
- Patentability margins depend on prior art searches; similar compounds or formulations published before 2013 could challenge validity.
- Novelty and inventive step are core criteria that the claims must satisfy.
- Patent scope can be challenged through opposition or invalidation procedures in key jurisdictions.

Conclusion
WO2013190582 covers pharmaceutical compositions and methods with potential broad claims, establishing a protective patent estate across multiple territories. Its strength relies on claim breadth, robustness against prior art, and strategic prosecution. The patent's value diminishes over time as it approaches expiration unless supplemented by additional filings or licensing agreements.
Key Takeaways
- The patent's scope includes formulations, manufacturing methods, and therapeutic uses.
- Claim breadth influences market exclusivity significantly.
- The patent family spans key jurisdictions, with expiration around 2033-2034.
- Competitors may file follow-up patents for derivatives or combination therapies.
- Patent validity depends on overcoming prior art challenges in each jurisdiction.
FAQs
1. What are the typical challenges in enforcing WO2013190582?
Prior art publications or existing patents referencing similar compounds or formulations threaten validity. Challenging the inventive step or novelty in specific jurisdictions can weaken enforcement.
2. How does claim scope affect potential licensing?
Broader claims facilitate cross-licensing and commercialization opportunities. Narrow claims restrict applicability but may be easier to defend.
3. Are there similar patents in this domain?
Yes, multiple patents likely cover related therapeutics, compound classes, or delivery systems, forming a dense patent landscape.
4. Can the claims be invalidated post-grant?
Yes, through oppositions or litigation at patent offices or courts, especially if prior art predates the filing date.
5. What strategies can extend patent life or coverage?
Filing divisional or continuation patents, developing new derivatives, or broadening use claims can prolong protection.
