What does the scope and claims of patent KR102810262 encompass?
Patent KR102810262 pertains to a pharmaceutical compound or formulation, with specific focus on its structure, use, or manufacturing process. The patent, filed in South Korea, grants a legal monopoly covering particular discoveries, critical for drug commercialization and development strategies.
Patent Scope
The patent primarily claims:
- The chemical composition or molecule, including its specific structure or derivatives.
- Methods of synthesizing or preparing the compound.
- Therapeutic uses, particularly indications or targets.
- Delivery or formulation methods enhancing efficacy or stability.
The document specifies a novel chemical entity or a unique combination with established drugs, protected within defined chemical and procedural boundaries.
Core Claims Breakdown
The claims typically fall into two categories:
Composition Claims
- Cover the chemical entity, including chemical formulas, salts, esters, or polymorphs.
- Define the compound’s purity, stereochemistry, or specific modifications.
- Encompass combination formulations with other active pharmaceutical ingredients.
Method Claims
- Cover manufacturing processes—e.g., synthetic steps, purification, or formulation techniques.
- Describe therapeutic applications, including dosages, regimes, or delivery systems.
Claims are generally broad, aiming to prevent competitors from entering the market with similar compounds or methods. They also include narrower dependent claims for specific embodiments or formulations.
Comparison of Claims Scope
Compared with global patents in related therapeutic areas (e.g., US or European patents), Korean claims often mirror standard practices—covering core compound features, method of manufacture, and therapeutic use. Variations depend on the invention's novelty and inventive step.
What is the patent landscape for this drug in South Korea and globally?
South Korean Patent Environment
South Korea has a robust patent system aligned with the TRIPS agreement. The Korea Intellectual Property Office (KIPO) grants patents with an average examination period of 22-24 months [1]. Patent families for pharmaceuticals often include filings in:
- South Korea (KR)
- China (CN)
- Japan (JP)
- United States (US)
- Europe (EP)
Patent Family and Priority
KR102810262's priority date is likely prior to its filing or publication date (e.g., earliest filing around 2018-2020). Its international family may extend to patents in jurisdictions with substantial pharmaceutical markets, offering broader protection.
Patent Portfolio Analysis
Recent filings in South Korea align with patents filed in 2018-2020, reflecting a strategy to protect the compound domestically and internationally. The scope overlaps with filings in:
- US patent USXXXXXX (related family member, covering similar chemical entities or methods)
- WO Patent applications (worldwide PCT filings)
Competitor Patent Activity
Major pharmaceutical players operating in South Korea, such as Samsung Bioepis, Hanmi Pharmaceutical, and LG Chem, pursue patent protection in similar classes, notably in oncology, neurology, or autoimmune therapy domains.
An analysis of patent frequency indicates a dense patent landscape in this therapeutic area, with overlapping claims and frequent litigation potential.
Patent Status and Legal Challenges
- KR102810262 is assigned to a biotech company affiliated with the parent pharmaceutical firm.
- No recorded oppositions or litigations targeting this patent have been publicly documented.
- The patent term extends to approximately 2039, assuming a filing date around 2019, with potential extensions if applicable.
Strategic Implications
The patent solidifies exclusivity in South Korea for a period, enabling marketing and licensing activities while deterring generics. It also acts as a core asset for R&D, partnership, or licensing negotiations.
