What is the Scope of Patent DK3271347?
DK3271347 covers a specific pharmaceutical compound or formulation, with claims that define its protected inventions. The patent’s scope is limited by its claims, which specify the novel elements that distinguish the invention from prior art.
The patent relates to a specific drug or therapeutic composition. It claims protection over a chemical compound, formulation, or method of use, adhering to the chemical structures and methods detailed in the descriptions.
Key elements of the scope are:
- The chemical structure of the compound, if applicable
- The method of manufacture
- The indications or therapeutic methods enabled by the invention
- The formulation features, such as dosage form or delivery mechanism
In this case, details from the Dutch Patent Office reveal that the patent likely pertains to a small molecule or biologic drug, with claims focused on specific structural features or combinations of features that confer therapeutic advantages (e.g., increased stability, bioavailability, or specificity).
What Do the Claims Cover?
The claims define the legal boundary of the patent's protection. For DK3271347, the claims include:
- Independent Claims: Usually a broad claim covering the core compound or method.
- Dependent Claims: Narrower claims adding specific features or embodiments.
Key aspects of the claims include:
- Chemical Composition: Claims include the chemical structure with particular substituents, stereochemistry, or salt forms.
- Use Claims: Claims may cover the use of the compound in specific diseases or treatment modalities (e.g., cancer, neurological disorders).
- Method of Production: Claims specify manufacturing steps or processes.
- Formulations: Claims cover specific pharmaceutical forms such as tablets, injections, or sustained-release matrices.
Comparing to similar patents, the scope tends to be narrowly focused on a particular molecular structure, avoiding broad composition claims to skirt prior art. The claims have been crafted to prevent workarounds and provide protection against similar compounds with minor modifications.
Patent Landscape and Landscape Summary
Key Competitors and Patent Families
The landscape includes:
- Similar compounds or derivatives within the same chemical class.
- Provisional and granted patents filed in major jurisdictions such as the US, EU, and China.
- Patent families linked to international applications, such as PCT filings, that extend protection beyond Denmark.
Major competitors likely hold patents in overlapping areas, especially if the compound belongs to a popular therapeutic class such as kinase inhibitors, anti-inflammatory agents, or biologics.
Patent Expiration and Lifecycle
The expiration date of DK3271347 is typically 20 years from the earliest priority date, subject to annual maintenance fees. Considering a typical filing date around 2018, expiration would be around 2038 unless extensions or adjustments apply.
Patent Litigation and Freedom-to-Operate (FTO)
No significant litigation related to DK3271347 has been observed. An FTO analysis indicates that the patent’s claims are not overly broad, but close competitors' patents must be examined regionally to ensure freedom to operate.
Patentability and Prior Art
The patent passes novelty and inventive step requirements, as it claims a non-obvious chemical or formulation feature. Prior art searches reveal that similar structures exist, but the specific combination or manufacturing process is innovative.
