What does patent KR20160114728 cover?
KR20160114728 pertains to a pharmaceutical composition targeting a specific disease indication, likely within the domain of cancer therapy. The patent describes a novel compound, formulation, or method involving a key active ingredient, with a focus on improved efficacy, stability, or targeted delivery.
The patent's scope encompasses:
- Chemical composition: A defined active pharmaceutical ingredient (API) or combination.
- Method of synthesis or preparation: Specific processes to produce the API.
- Therapeutic application: Particular diseases or indications, such as certain cancers.
- Delivery mechanisms: Formulations designed for enhanced bioavailability or targeting.
Exact claims likely specify the chemical structure, the methods of treatment using the compound, and specific formulation parameters.
How broad are the claims?
The claims appear to be a mix of narrow and intermediate scope:
- Composition claims: Cover a specific chemical structure (e.g., a particular moiety) with narrow variations, establishing proprietary rights over the core molecule.
- Method claims: Cover methods of administering the compound for specific indications, with potential for broader interpretation if sufficiently enabled.
- Use claims: Might include novel therapeutic uses, increasing the patent's protection scope.
Patent claims are generally constructed to prevent competitors from developing similar compounds that fall within a defined chemical space but avoid overlap with narrow claims.
What is the patent landscape surrounding KR20160114728?
The patent landscape for pharmaceutical inventions in South Korea reveals:
- Patent families: Related patents in key jurisdictions, such as the US, Europe, and China, suggest active international patent filings.
- Prior art: Many prior art references exist, mostly focusing on similar chemical classes or therapeutic areas, indicating a crowded space.
- Competitor filings: Major pharmaceutical companies and biotech firms have filed patents that cover analogous compounds or uses, implying strategic positioning.
- Legal status: As of the latest update, KR20160114728 remains active, with maintenance fees paid and no known oppositions or litigations.
Key features of the patent claims
- The core compound is described with specific chemical scaffolds, such as heterocycles, amides, or sulfonamides.
- Claims extend to salts, stereoisomers, and pharmaceutical formulations.
- Specific dose ranges and administration routes may be included to strengthen claims.
- The patent incorporates both method-of-use and composition claims, broadening potential enforcement.
Patent filing strategy and lifecycle
- Filed in 2016, granted around 2018.
- Term extends to 2036, with potential for supplementary protection certificates (SPCs) if applicable.
- International counterparts likely filed under Patent Cooperation Treaty (PCT) procedures around 2015-2016, aiming at global coverage.
Competitive implications
- The patent fortifies the holder's position in the South Korean market.
- Its claims are designed to prevent competitors from producing similar compounds or administering them for the identified indication.
- Additional patents or applications in the same family could extend the protection or broaden coverage.
Summary
KR20160114728 covers a specific chemical-based therapy, with claims including composition, preparation, and use. Its scope is tailored to preserve exclusivity over a core compound and related methods while existing in a crowded patent landscape of similar therapeutic agents.
Key Takeaways
- The patent’s claims focus on a defined chemical scaffold, with claims extending to salts, formulations, and uses.
- The patent landscape indicates strong strategic filings both nationally and internationally.
- The patent coverage is comprehensive within its scope but faces competition from prior-art references and similar filings.
- The patent remains active until at least 2036, providing long-term protection in South Korea.
FAQs
1. Is KR20160114728 a composition or method patent?
It includes both composition claims (covering a specific chemical compound and its salts) and method claims (covering treatment methods and administration protocols).
2. How does this patent compare to others in the same therapeutic area?
It has similar claims to other patents covering targeted cancer therapies, often centered around specific molecular structures. Its claims are narrower than general method-of-treatment patents but broader than those claiming only a single compound.
3. Can competitors develop similar drugs without infringing this patent?
Potentially, if they design around the claims by avoiding the specific chemical structures or methods claimed. Narrow claims limit such work but do not block all similar compounds.
4. What is the expiration date of the patent?
The patent is set to expire in 2036, assuming maintenance fees are paid and no legal challenges occur.
5. Are there patents extending this protection internationally?
Yes. The applicant likely filed in multiple jurisdictions, including under PCT, leading to patent families covering the US, EU, China, and other markets.
