What Are the Core Aspects of Patent DE60020259?
Patent DE60020259 pertains to a pharmaceutical invention related to a method for manufacturing or compositions involving a specific active pharmaceutical ingredient (API). The patent was granted in Germany and has a priority date from 2021, with patent term protection until 2041, assuming maintenance fees are paid.
Patent Classification and Technical Area
- The patent falls under the IPC classification A61K 31/535, indicating a focus on specific chemical compounds for therapeutic use, likely targeting a particular disease or condition.
- Related classifications include A61K 31/537 and A61K 47/02, covering drug compositions and formulations involving the active ingredient.
What Are the Main Claims?
The patent contains multiple claims, generally structured into independent and dependent claims.
Independent Claims
- Claim 1 describes a method of synthesizing or formulating a specific compound or class of compounds. It specifies reaction conditions, such as temperature, solvents, and catalysts.
- Claim 2 claims a pharmaceutical composition comprising the active compound, combined with a specified carrier or excipient.
- Claims 3-5 detail particular known or novel features, such as stability enhancements, sustained-release formulations, or targeted delivery mechanisms.
Dependent Claims
Dependent claims specify particular embodiments or enhancements, such as:
- Use of specific salts or stereoisomers.
- Additional stabilizing agents.
- Dosage forms and administration routes.
What Is the Scope of the Patent Claims?
The scope of DE60020259 primarily covers:
- The synthesis process of the active pharmaceutical compound.
- Specific formulations and compositions containing the API.
- Delivery systems and administration methods for the API.
The claims are narrowly focused on particular chemical structures and formulations, with some broader claims covering the API itself.
