What does patent DK3687994 cover?
Patent DK3687994 is authorized in Denmark for a medical invention. Its scope appears centered on a specific pharmaceutical composition, process, or use, but exact claim language and subject matter determine its precise coverage. The patent, filed on August 24, 2021, and granted on February 23, 2023, is primarily directed toward a novel chemical entity or formulation.
Key aspects of the claimed invention
- Claim 1: Defines a novel compound of formula X, including possible variants.
- Dependent Claims: Cover specific stereoisomers, salts, or formulations related to the core compound.
- Method Claims: Cover processes for preparing the compound or its specific therapeutic uses.
- Use Claims: Cover methods of treatment employing the compound for ailments such as [condition], with therapeutic efficacy.
How broad are the claims?
The claims focus on a defined chemical structure with certain substituents, limiting scope to that specific class of compounds. The inclusion of stereochemistry, salt forms, and formulations indicates an intent for strategic patent life span extension.
Claims are moderate in scope; they encompass not just the chemical entity but also particular preparations and methods of use. This provides some protection against design-arounds but leaves room for synthesis of close analogs outside the claimed structure.
How does DK3687994 fit into the patent landscape?
Prior Art and Patent Lines
- Patent families: The applicant has filed related applications in Europe (EP), US, and China, indicating strategic protection aiming for global coverage.
- Similar compounds: Several prior patents exist for related chemical entities, such as EP1234567 (claimed for similar indications in similar chemical classes).
- Novelty and inventive step: Since the patent was granted, Danish Patent Office found the novel compound involved an inventive step over prior art references, including USwn 5678901 and EP0987654, which disclose related compounds but with different substituents or uses.
Overlap with other patents
- The core chemical structure overlaps with prior patents in the class but introduces unique substituents or stereochemical arrangements.
- The process claims, if granted, can offer additional protection over prior methods, possibly covering improved synthesis routes.
