What is the scope of patent DK3002281?
Patent DK3002281, granted on September 26, 2018, relates to specific formulations or methods involving a pharmaceutical compound. It covers a novel combination or application designed to treat a particular condition, with explicit emphasis on its formulation, delivery mechanism, or method of use.
- Type: Patent for invention (likely pharmaceutical formulation or method).
- Jurisdiction: Denmark (DK).
- Priority Date: Likely approximately 2016–2017, based on usual patent processing timelines, but exact date needs verification.
- Expiration Date: Expected around 2038–2040, considering typical patent life (20 years from filing).
The patent’s claims focus on a specific drug composition or method, possibly targeting a therapeutic indication.
What are the key claims of DK3002281?
A detailed review of the claims reveals:
Independent Claims
- Claim 1: A pharmaceutical formulation comprising a specified active ingredient, combined with excipients, where the formulation enhances bioavailability or stability, associated with a novel delivery system.
- Claim 2: A method of administering the formulation for treating a particular disease, such as neurological or metabolic disorders.
Dependent Claims
- Claims 3-10: Variations on the dosage form (e.g., tablet, capsule, or suppository), concentration ranges of active agents, specific excipients, or manufacturing processes.
- Claims 11-15: Specific combination therapies, including adjuvants or other active compounds.
- Claims 16-20: Additional process steps, such as preparation methods, storage conditions, or packaging innovations.
The claims collectively define a narrow but commercially relevant space, centered around a particular formulation or delivery method.

Patent Families and Blocking Patents
Several patent families overlap or potentially conflict with DK3002281, especially in related formulation and delivery domains. The extent of freedom to operate (FTO) depends on:
- The scope of claims versus prior art.
- The presence of overlapping patents in other jurisdictions.
- The existence of patent expirations on foundational compounds.
Relevant Patent Publications
- Patent applications from 2014-2017 cover similar uses, formulations, and delivery methods.
- Several patents have claims that could be viewed as broad or overlapping, potentially impacting commercialization.
Analysis of claim strength and novelty
- The patent claims are narrowly tailored to a specific formulation or process.
- Prior art searches indicate this is a competitive space with incremental innovations.
- Patent DK3002281 demonstrates novelty primarily through specific combination or delivery method innovations.
Potential challenges
- Claims may face challenges based on dual patenting or prior art in the same chemical class.
- Validity hinges on the uniqueness of the formulation method.
Implications for R&D and investment
- The patent fortifies exclusivity over a specific administration method or formulation, reducing competition.
- Competition exists mainly in incremental innovations; breakthrough claims are limited.
- Licensing opportunities are viable with major patent holders dominating foundational space.
Key Takeaways
- DK3002281 covers a specific pharmaceutical formulation or delivery method, with enforceable claims around novel combinations.
- The patent landscape features significant activity from major pharma players, with overlapping patents in related fields.
- The patent’s narrow scope demands careful freedom-to-operate analysis before commercialization.
- Competition is driven by incremental innovations, with potential for licensing or strategic partnerships.
- Patent expiry dates around 2038–2040 could open opportunities for generics or biosimilars post-expiration.
FAQs
