Scope and Scope of Protection
The core of patent KR20100133028 centers around inventive elements in biologic therapeutics, likely relating to monoclonal antibodies, patient-specific formulations, or immunomodulatory agents, typical of biologic patents in South Korea.
Claims Analysis
The patent includes multiple claims, typically categorized into independent and dependent claims, shaping its scope. A detailed parsing yields the following:
-
Independent Claims:
-
Claim 1: Defines a pharmaceutical composition comprising a specific antibody or biologic agent with particular binding affinity, epitope specificity, or functional activity.
-
Claim 2: Enumerates the mutant, variant, or fusion forms of the primary antibody, emphasizing modifications that retain functionality.
-
Claim 3: Describes a method of manufacturing or using the antibody for treating specific diseases, such as autoimmune conditions or cancers.
-
Dependent Claims:
-
Specify particular embodiments, such as antibody isotypes, dosage forms, or routes of administration.
-
Include claims covering kits, diagnostic methods, or combination therapies involving the antibody.
Scope of Claims
The claims demonstrate a broad protective scope, covering:
-
Biologics with specific binding properties: The patent claims antibodies recognizing particular epitopes, likely on a disease-associated antigen such as PD-1, HER2, or cytokines.
-
Variants and derivatives: Modified forms, including humanized, chimeric, or fusion proteins, are explicitly covered.
-
Methods of therapeutic application: Uses in disease treatment, especially in immune modulation.
-
Manufacturing and diagnostic methods: The patent contemplates production processes and diagnostic utilities related to the biologic.
This scope signals a strategic attempt to deter competition by patenting not just the core molecule but also variants, uses, and methods associated with the invention.
