Scope of the Patent
Claims Analysis
A patent’s claims define its scope of legal protection. KR20170103848’s claims can be broadly categorized into two types:
- Independent Claims: These specify the core inventive concept, often covering the chemical compounds or compositions directly associated with the invention.
- Dependent Claims: Detail specific embodiments, formulations, or methods that narrow down or specify particular variants.
Typical Features of KR20170103848 Claims
- Chemical structure claims: Claims cover a novel chemical scaffold with particular moieties that enhance efficacy or reduce side effects.
- Pharmaceutical composition: Claims include formulations comprising the novel compound, optionally combined with excipients or carriers.
- Therapeutic method: Claims encompass methods of treating specific diseases using the claimed compounds or compositions.
- Delivery systems: Claims may specify innovative delivery mechanisms such as nanocarriers, sustained-release formulations, etc.
Claim Language and Patent Scope
The claims are written to emphasize novelty, inventive step, and industrial applicability under Korean patent law. Often, broad claims aim to cover all potential use cases, while narrower claims focus on specific compounds or treatments.
Scope Limitations
- The scope is constrained by prior art references, both domestic and international, particularly mutations or derivatives close to existing pharmaceuticals.
- Any overlap with existing patents in the same class can lead to limitations or require claim amendments during prosecution.
