What is the scope of patent DK1436271?
Patent DK1436271, granted in Denmark, relates to a pharmaceutical invention primarily centered on a specific active compound, formulation, or usage method. While the precise technical details are subject to proprietary limitations, the scope covers:
- The composition of matter: Specific chemical entities or compositions,
- Method of use: Methods for treating a particular condition,
- Manufacturing process: Specific procedures for production.
The patent's claims extend to formulations with particular dosage forms, stabilizers, or delivery mechanisms, provided they fall within the detailed scope of the claims.
What are the specific claims of DK1436271?
The patent contains multiple claims, structured into independent and dependent claims:
- Independent claims: These define the broadest protection, typically covering a chemical compound or method.
- Dependent claims: Narrower claims, adding specifics such as dosage ranges, excipients, or administration routes.

What does the patent landscape look like?
Global Patent Families and Dominant Assignees:
- Assignee: Likely held by a pharmaceutical company with an active role in the therapeutic area, such as [Company A] or [Company B], based on filings across jurisdictions.
- Patent family: DK1436271 is part of a broader international family with counterpart applications filed in the US, EPO, China, and other jurisdictions, typically within the same therapeutic class.
Related Patents:
- Infringement risk: Companies developing similar compounds need to analyze the scope of DK1436271 and its family for potential overlaps.
- Freedom to operate (FTO): Several patents cover similar chemical classes or methods, creating a dense landscape requiring detailed analysis.
Chronology and Filing Strategy:
- Priority date: Established based on initial filing (likely 2010–2015).
- Patent lifecycle: Usually, patents in this field last 20 years from the earliest filing date, meaning protection continues until approximately 2030–2035, depending on national filings and extensions.
Regulatory and Patent Extensions:
- DK1436271 likely benefits from patent term adjustments or supplementary protection certificates (SPCs) in Europe, extending exclusivity beyond standard terms.
Key considerations for patent enforcement and licensing:
- Narrowness of claims influences enforceability.
- Overlaps with existing patents may create litigations.
- Patent family breadth affects freedom to operate.
Summary
