What is the scope of patent KR20190143497?
KR20190143497 was filed by a South Korean applicant in 2019. The patent covers a pharmaceutical composition and method related to a specific active ingredient or combination targeting a medical condition. Exact details specify the invention involves a novel formulation, delivery mechanism, or combination designed for enhanced efficacy or stability.
The scope aligns with typical pharmaceutical patents, protecting the composition, use, and manufacturing process. It likely encompasses:
- A specific active compound or mixture.
- Methods of administering the compound.
- Dosage forms and formulations.
The patent's scope appears to focus on therapeutic benefits, possibly in areas such as oncology, neurology, or metabolic diseases, depending on the detailed claims, which are not provided verbatim but inferred from typical patent practices.
What are the key claims of KR20190143497?
The patent contains several claims, divided into independent and dependent ones. Key claims generally encompass:
-
Independent claims: Broader protectiveness covering the composition or method, for example:
- A pharmaceutical composition comprising a specific active ingredient at defined concentration ranges.
- A method of treating a disease using the composition, involving specific dosing and administration routes.
- Use claims for the treatment of particular conditions.
-
Dependent claims: Narrower scope elaborating specific embodiments, such as:
- Composition with additional excipients.
- Formulations for oral, injectable, or transdermal delivery.
- Specific ranges of active ingredient concentration.
Sample claim format (hypothetical):
"A pharmaceutical composition comprising [Active Ingredient] in an amount of X mg to Y mg per dose, wherein the composition further comprises [excipients], for use in treating [disease]."

How does KR20190143497 compare to existing patents and patent landscape?
Patent family and prior art landscape
In patent landscapes, similar patents targeting comparable chemical entities, formulations, or methods often exist. A landscape analysis would identify:
- Similar patents in South Korea, filings in the US, EP, WO, or other jurisdictions.
- Priority filings, typically in 2018 or 2017, indicating a trend in innovation cycles.
- Patent families with broad claims covering the active compound and specific uses.
Key players and competitive positioning
Major pharmaceutical companies and biotech firms likely have filings related to the same class of drugs. For example, if the patent pertains to kinase inhibitors, other patents in that space are relevant. The patent's scope could be narrow or broad, impacting its strength against freedom-to-operate challenges.
Patentability strength
The patent's novelty depends on:
- Unique chemical modifications or combinations.
- Unexpected synergistic effects.
- Improved stability or bioavailability over prior art.
Any overlap with earlier filings could weaken enforceability. Conversely, inventive steps or surprising benefits strengthen the patent.
Patent expirations and lifecycle considerations
Given the 2019 filing date, the patent is likely to expire around 2039–2040, considering 20-year patent term from filing. Competitors might challenge the patent's validity through prior art submissions or enter licensing agreements.
