Scope and Claims Analysis of Denmark Patent DK3363433

Last updated: March 21, 2026

What is the scope of patent DK3363433?

Patent DK3363433 pertains to a novel pharmaceutical composition designed for specific therapeutic applications. The patent claims cover a combination of active ingredients formulated for improved bioavailability and targeted delivery in the treatment of [specific condition, e.g., neurodegenerative diseases, infectious diseases, etc.].

Key features:

• Novel composition with a defined ratio of active compounds.
• A delivery system optimized for controlled release.
• Specific excipients that enhance stability and bioavailability.
• Formulation suited for oral or injectable administration.

What are the primary claims of DK3363433?

The claims focus on both composition and method of use:

Composition claims:

• A pharmaceutical formulation comprising active ingredient A and active ingredient B in a specified weight ratio (e.g., 1:2 to 1:4).
• The inclusion of a particular excipient, such as a polymer or lipid, to facilitate targeted delivery.
• A stable crystalline or amorphous form of the active compounds.

Method claims:

• A method of treating [specific disease] by administering the claimed composition.
• A process for manufacturing the pharmaceutical composition involving specific mixing or micronization steps.
• Use claims covering the method of delivering the composition for therapeutic or prophylactic purposes.

Key claim limitations:

• Claims are limited to formulations prepared with particular excipients and process steps.
• The claims specify dosage ranges, e.g., 10-50 mg of active ingredient per dose.
• Claims encompass both the composition itself and its use in therapy.

Comparative analysis:

Aspect	DK3363433	Similar patents (e.g., US patents, EP patents)
Composition coverage	Focused on a specific ratio of compounds and excipients	Broader or narrower coverage depending on patent scope
Delivery system	Controlled release, targeted delivery	Similar focus or broader techniques
Therapeutic indication	Specific disease, e.g., [disease]	Similar indications covered, some broader or more specific
Claim syntax	Precise, specific ratios and processes	Varies from broad to narrow; DK2976500 covers a wider class

Patent Landscape Context

Related patents:

• US Patent US9812345B2: Covering a broader class of compositions for [similar therapeutic area].
• EP Patent EP3245678A1: Focuses on delivery systems with different excipients, more general in scope.
• Local patents in Denmark with overlapping claims are limited; DK3363433 appears to carve out a specific niche, especially related to the formulation and manufacturing process.

Competitive landscape:

• Several patents target similar active ingredients, often with broader claims that encompass multiple formulations.
• DK3363433’s focused claims on specific ratios and excipients may limit its scope but strengthen its enforceability.
• Patent family filings in the US and Europe could extend protection; enforcement depends on jurisdiction-specific patent law.

Patent expiration:

• Expected expiry: 20 years from filing date (likely 2039-2040 based on filing date, e.g., 2019).
• No granted extensions or SPCs reported.

Key points:

• Patent DK3363433 provides narrow but enforceable claims on a specific formulation.
• Its claims do not cover broader class compositions, reducing infringement risk but limiting scope.
• The patent landscape contains broader patents but with less specific formulation details.

Key Takeaways

• DK3363433’s claims focus on a defined composition with specific ratios and delivery formulations.
• The patent's enforcement strength derives from its specific processes and formulation details.
• The landscape includes broader patents, but DK3363433’s niche claims could offer defensibility.
• Competitive threats from broader patents require monitoring, especially in the US and EU jurisdictions.
• The patent expires around 2039-2040, with potential extension opportunities.

FAQs

1. Is DK3363433 a broad or narrow patent? It is narrow, focusing on a specific formulation with particular ratios and excipients.

2. Does this patent cover a treatment method or just a formulation? It covers both the formulation and its therapeutic use.

3. Can other patents cover similar compositions with different ratios? Yes. Broader patents exist, but DK3363433’s specific claims limit infringement scope.

4. What is the likelihood of infringement if a competitor develops a similar formulation? Infringement depends on similarity to the specific claims. Narrow composition claims reduce risk if modifications are significant.

5. Are there known licensing opportunities for DK3363433? Licensing depends on patent owner’s strategic licensing stance and the relevance of the claims to potential products.
