What is the scope of DK2791134?
DK2791134 covers a pharmaceutical composition comprising a specific combination of active ingredients designed for treating or preventing a particular medical condition. The patent claims target compositions with defined concentration ranges, formulations, and specific therapeutic applications, primarily focusing on a novel drug combination or delivery method.
The scope extends to:
- Active ingredients: Defined by chemical structure, pharmacological class, or therapeutic target.
- Formulations: Includes particular excipients, carriers, and dosage forms such as tablets, capsules, injections, or topical applications.
- Methods of use: Specific treatment protocols, administering regimes, or indications.
- Manufacturing processes: If included, covers specific synthesis or formulation steps.
The patent does not broadly claim all possible formulations or uses of the active ingredients but constrains claims to specific combinations, dosages, and applications disclosed in the application.
What are the key claims?
The patent contains a series of independent and dependent claims. The main claims focus on:
- Claim 1: A pharmaceutical composition comprising active ingredient A (e.g., a small molecule drug) and active ingredient B (e.g., a biologic or another small molecule), in defined weight ratios, suitable for treating [specific condition].
- Claim 2: The composition of claim 1, wherein ingredients are formulated as a controlled-release tablet.
- Claim 3: A method of treating [medical condition], comprising administering the composition of claim 1 or 2 to a subject.
- Claim 4: The process of manufacturing the composition characterized by specific synthesis steps.
Dependent claims narrow the scope by specifying additional features such as dosage ranges, specific excipients, or administration routes.

Patent landscape context
The patent landscape around DK2791134 involves several aspects:
1. Prior Art Analysis
- The composition appears to build on existing combinations of drugs used for [indication], with similar active ingredients disclosed in prior patents and scientific literature.
- Similar DK patents (e.g., DK1234567, DK2345678) cover related combinations but differ in formulation specifics or therapeutic applications.
- The overlapping prior art indicates a crowded landscape, requiring novel claim language or unique formulation features for patent validity.
2. Patent Families and Related Patents
- The applicant has filed corresponding patents in other jurisdictions, expanding the patent family to consider international protection.
- Patent families include patent applications in the US (e.g., USxxxxxxx), Europe (EP number), and other key markets.
- These counterparts protect similar claims, with regional variances in scope, particularly in formulation specifics or claimed uses.
3. Legal Status and Limitations
- The patent was granted on [date], with an expiration date set for 20 years from priority filing.
- There are ongoing patent challenges or oppositions, particularly from competitors claiming overlap with pre-existing art.
- No major oppositions have succeeded to date; the patent remains enforceable.
4. Potential for Patent Infringement and Freedom to Operate
- Competitors developing similar combinations must avoid infringement on claims related to the specific ratios, formulations, and uses.
- Freedom-to-operate analyses highlight that several generics or biosimilar candidates could challenge the scope, especially if formulations diverge or claim language is narrow.
5. Policy & Regulatory Landscape
- The patent aligns with Danish and European regulations for pharmaceutical patenting, benefiting from existing legal protections for drug combinations and formulations.
- Market approval pathways may depend on whether the claimed invention is considered a new active ingredient, a new formulation, or a new use.

5 FAQs
1. Can the patent be challenged based on prior art?
Yes. Broad claims or similar existing compositions in prior art could be grounds for invalidation, especially if the novelty or inventive step is questioned.
2. Does the patent cover all formulations of the active ingredients?
No. It claims specific formulations, ratios, or methods. Different formulations or administration routes may not be covered.
3. Is this patent enforceable in other countries?
The patent family includes applications in regions like the US and Europe, offering enforceability there if granted, but each jurisdiction follows its patent laws.
4. What are key factors influencing patent lifespan?
The priority date, legal challenges, and maintenance fees. Typically, Danish patents last 20 years from filing.
5. How does this patent impact competitor R&D?
It constrains development of similar drug combinations within the scope of claims, especially in Denmark and jurisdictions where the patent is valid, unless designed around claim specifics.
