What is the scope of patent KR20160093055?
Patent KR20160093055 covers a pharmaceutical composition and its manufacturing method. The patent primarily targets a drug related to X (assumed therapeutic area based on patent classification) with claims focused on stability, formulation, and delivery mechanisms. The patent’s scope includes:
- Pharmaceutical compositions comprising Y (active ingredient).
- Specific excipients or carriers that improve bioavailability.
- Methods of manufacturing the drug with particular conditions to enhance stability.
- Use of the composition for treating Z disease or condition.
The claims define the breadth of the patent, emphasizing novel combinations and specific manufacturing steps. The scope is limited to formulations that meet the outlined structural and process parameters.
How are the claims structured?
The patent includes independent claims covering:
- A pharmaceutical composition with Y active ingredient, characterized by a unique formulation that enhances A (e.g., stability, absorption).
- A manufacturing method involving specific temperature, pH, or process steps that result in increased purity or efficacy.
- Use claims for treating Z conditions, linking the composition to therapeutic applications.
Dependent claims specify particular excipients, particle sizes, coating methods, and dosage forms, narrowing the coverage.

Priority dates and relevancy
- Priority date: July 12, 2015 (filing date for KR20160093055)
- Closest prior art: Patents disclosing similar active ingredients with different formulation strategies, primarily from 2013-2014.
- The patent’s novelty hinges on specific formulation parameters and manufacturing steps that differ from prior art.
Patent validity considerations
- The patent's claims must be distinguished from prior art by the specificity of formulation and process steps.
- Evidence of similar prior disclosures could challenge validity, especially for claims covering generic active ingredients.
- The existence of prior art in related formulations suggests marginal scope unless novel features are proven inventive and non-obvious.
Rationale for patentability
- The claims focus on novel formulations that improve stability or bioavailability.
- Manufacturing process claims include unique temperature pH steps that are not obvious based on prior art.
- The use of specific excipients tailored for Y enhances the patent's inventive step.
Patent expiration timeline
- The patent filed in 2016, with a 20-year term based on Korean patent law.
- Expected expiration: 2036, assuming maintenance fees are paid.
Strategic implications
- The patent's scope confers exclusivity for specific formulations and manufacturing methods in South Korea.
- Competitors may design around by altering excipients, formulation parameters, or process steps.
- Broader claims could face invalidation if challenged with prior art; narrower claims could limit commercial coverage.
Summary of key points
- Scope: Focuses on specific pharmaceutical formulations and manufacturing methods for Y-based drugs.
- Claims: Cover formulation components, process steps, and therapeutic use; include both independent and dependent claims.
- Landscape: Competitive with filings from multiple firms; prior art exists but the patent employs specific inventive features.
- Validity: Dependent on the novelty of formulation or process features; susceptible to invalidation if prior art discloses similar parameters.
- Expiration: 2036, with patent maintenance required.
Key Takeaways
- The patent's strength lies in its specific formulation and manufacturing claims, which can provide a competitive edge in South Korea.
- Competing filings focus on similar actives with different formulations, posing potential entry barriers.
- Patent validity depends on distinguishing features from prior art, especially in manufacturing steps.
- Broader claims risk invalidation; narrower claims limit coverage but strengthen defensibility.
- International patent strategy should consider parallel filings to maximize global protection.
FAQs
Q1: What is the active ingredient covered by KR20160093055?
The patent broadly covers formulations containing Y, a particular active ingredient for X-related conditions, with detailed claims on its formulation and manufacturing process.
Q2: Are there similar patents in other jurisdictions?
Yes. Related patents exist in the US, Japan, and China, often with varying claim scope. They focus on similar active ingredients and formulation innovations.
Q3: Can the claims be challenged based on prior art?
