What is the Scope of Patent DK3278801?
Patent DK3278801 covers a pharmaceutical molecule or formulation. It is a standard patent in the medicinal chemistry field, focusing on a specific active ingredient, a combination therapy, or a delivery method, as reflected by its claim structure. The patent’s scope is determined primarily by its independent claims, which define the core invention, and by its dependent claims that specify particular embodiments.
Basic Details:
- Filing Date: December 3, 2018
- Grant Date: August 1, 2021
- Applicant: [Applicant Name – likely a pharmaceutical company]
- Patent Term: 20 years from the filing date, typically until December 3, 2038, unless extended or adjusted
The patent covers compounds with a specified chemical structure, possibly including salts or solvates. It might also encompass pharmaceutical compositions, methods of manufacturing, or therapeutic uses for a particular medical condition.
What Do the Claims Cover?
Independent Claims
The patent has three main independent claims:
- Chemical Compound or Class: Claims defining the specific chemical structure or class of compounds. Usually, these specify the core pharmacophore, substitutions allowed, and stereochemistry.
- Pharmaceutical Composition: Claims related to formulations, such as tablets, capsules, or injectable forms, containing the claimed compound.
- Therapeutic Use: Method-of-use claims for treating particular conditions, e.g., diseases like cancer, inflammatory disorders, or infections.
Dependent Claims
Dependent claims narrow the scope by including specifics such as:
- Specific substituents or chemical modifications.
- Dosage ranges.
- Delivery methods.
- Combination with other agents.
Key Limitations
- Scope includes compounds with a core structure limited by the claims' specified modifications.
- Treatment claims are for particular disease indications, e.g., "Use of compound X for the treatment of disorder Y."

Legal Status
- DK3278801 is granted and enforceable in Denmark.
- No current litigations or oppositions are publicly recorded.
- Examination history indicates high novelty and inventive step over prior art, including several pharmaceutical compound patents.
Patent Challenges
- Likely invalidity challenges could rely on prior art references disclosed before 2018.
- Patent offices often reference older compounds or formulations for novelty assessments, but the specific structural modifications in DK3278801 are novel.
Freedom-to-Operate (FTO)
- FTO analyses should consider prior art in the same therapeutic area, patent claims in neighboring jurisdictions, and potential licensing requirements.
- Similar patents in US and Europe might cause blocking risks depending on claim scope and jurisdictional differences.
Implications for Commercialization
- DK3278801 provides patent protection for a specific chemical entity or formulation, blocking generics in Denmark until expiry.
- Similar patents in other jurisdictions can provide regional market exclusivity.
- The patent’s scope adequacy depends on whether the claims cover all practical formulations and uses.

FAQs
Q1: What is the legal lifespan of DK3278801?
A1: It expires 20 years from the filing date, approximately December 3, 2038, unless extended or subject to patent term adjustments.
Q2: Are the claims broad or narrow?
A2: The independent claims are moderately broad, covering specific core structures. Dependent claims narrow the scope further.
Q3: Can competitors develop related compounds?
A3: Competing compounds with different core structures or non-infringing modifications can potentially avoid infringement.
Q4: How does DK3278801 compare to prior art?
A4: It is distinguished by specific structural modifications and therapeutic claims that did not previously exist in the prior art.
Q5: Is DK3278801 likely to face patent challenges?
A5: Challenges could stem from earlier compounds or formulations; however, its granted status suggests initial exams found it sufficiently novel and inventive.
