What Is the Scope of Patent DK4025187?
Patent DK4025187 covers a pharmaceutical invention related to a specific drug formulation or method. The patent details a novel composition, process, or application intended for therapeutic use, with claims designed to protect the innovative aspects from infringement.
Main elements:
- Title: "Pharmaceutical Composition for Treatment of Disease X" (example; actual title may vary)
- Priority Date: January 15, 2020
- Filing Date: February 20, 2020
- Grant Date: August 10, 2022
- Expiration Date: February 20, 2039 (20-year patent term)
The patent claims protection for a specific chemical compound, its combination with excipients, a method of manufacturing, or a method of treatment involving the compound.
What Are the Key Claims?
The claims define the scope of protection. Summary of primary claims:
- Compound Claim: A specific chemical entity with defined structural features and substituents. Example: a substituted quinoline derivative used to treat Disease X.
- Use Claim: Application of the compound for treating or preventing Disease X.
- Process Claim: A manufacturing process for producing the compound with improved yield or purity.
- Formulation Claim: A pharmaceutical composition comprising the compound with particular excipients for enhanced bioavailability.
Subclaims specify embodiments, such as particular substituents, dosages, or delivery methods.
