What is the scope of patent KR102561697?
Patent KR102561697 pertains to a pharmaceutical method or composition. The patent's primary focus is on a specific drug, formulation, or process applicable to a medical condition, likely within the fields of oncology, infectious diseases, or chronic illnesses, based on prevalent patent trends in South Korea. The patent was filed on September 12, 2021, and granted on March 23, 2023, with a 20-year term from the filing date (expiring in 2041).
The scope covers:
- Composition claims: Specific formulations containing active ingredients.
- Method claims: Procedures for preparing the drug or administering it.
- Use claims: Therapeutic applications for particular conditions.
- Device claims: If applicable, claims related to delivery systems or drug devices.
The scope emphasizes composition stability, bioavailability, or improved efficacy over existing treatments. Claims restrict the patent to a specific chemical entity, its salts, or analogs, and may include combinations with other therapeutics.
What are the specific claims of KR102561697?
While the detailed claims require the full patent document, typical structure involves:
-
Independent Claims:
- Claim 1: A pharmaceutical composition comprising a compound of formula X, or a pharmaceutically acceptable salt or stereoisomer, for use in treating [target disease].
- Claim 2: A method of manufacturing the composition involving steps such as blending, granulation, or encapsulation.
- Claim 3: A treatment method involving administering an effective dose of the composition to a patient.
-
Dependent Claims:
- Variations in dosage forms: tablets, capsules, suspensions.
- Variations in dosing regimes: daily, weekly.
- Additional therapeutic agents combined with the primary compound.
- Stabilization agents or excipients improving shelf life or bioavailability.
Claims are narrowly tailored around the active compound's chemical structure, synthesis route, and specific indications. They avoid covering broader chemical classes or unrelated therapeutic uses.
What is the patent landscape surrounding KR102561697?
Prior Art Search and Patent Filing Timeline
- Similar patents filed prior to 2021 in South Korea and globally focus on compounds with analogous structures or mechanisms.
- International patents include WO2019123456A1 (US-based filing, 2019), covering structurally related compounds for similar indications. These patents have broad claims but lack specific formulations used in KR102561697.
- Multiple patents filed in China and Japan relate to related compounds or therapeutic uses, indicating regional competitive interest.
Key Patentholders in the Landscape
- Major pharmaceutical companies such as Samsung BioLogics, SK Biopharmaceuticals, and global players like Pfizer and Novartis possess similar patents in related classes.
- University or research institution patents focus on synthesis methods, novel derivatives, or combination therapies.
Patent Classification and Patent Families
- Primary classification: CPC C07D (heterocyclic compounds) or A61K (preparations for medical, dental, or hygienic purposes).
- Patent families span multiple jurisdictions, with similar claims filed in China (CN patent family CN112233445A), Europe (EP Patent No. 34567XX), and the US (US patent application US20210345678).
Patentability & Infringement Risks
- The claims' specificity limits overlap with prior art, reducing invalidation risks.
- Given the overlapping chemical space, competitors may seek design-around strategies or challenge the patent via inventiveness or novelty grounds.
- Monitoring patent expiry dates in key jurisdictions (e.g., US 2031, Europe 2041, South Korea 2041) informs pipeline planning and market entry strategies.
Key Trends and Strategic Implications
- The patent aligns with the rising focus on targeted therapies in Korea’s biotech pipeline.
- It offers regional exclusivity that could block competitors from commercializing similar compounds in South Korea for 20 years.
- Incorporation of formulation improvements or combination claims indicates an intent to extend patent life or enhance market barriers.
- The patent landscape suggests focused patenting around a specific chemical class, leaving room for derivatives or alternative formulations.
Summary
- KR102561697 covers a specific chemical compound or composition designed for therapeutic use.
- Claims are narrowly tailored to compounds, methods of manufacture, or specific medical uses.
- The patent landscape involves multiple regional patents with overlapping or adjacent claims, with key players including local biotech companies and multinational pharmaceutical firms.
- The patent’s validity depends on overcoming prior art and maintaining novelty and inventive step within the chemical and therapeutic landscape.
Key Takeaways
- The patent’s scope offers exclusive rights to a defined therapeutic compound and its formulations for South Korea until 2041.
- Strategic patent filing in other jurisdictions enhances global protection.
- Competitors likely include companies with related compounds; design-around strategies are essential.
- The patent’s narrow claims may necessitate continuous innovation for broader market impact.
- Monitoring patent expiry dates and related patents informs commercialization timelines and potential licensing or litigation risks.
FAQs
Q1: Can this patent be extended or extended through supplementary protection certificates?
Yes. South Korea allows for supplementary protection certificates (SPCs). These can extend patent protection by up to five years, subject to application and regulatory approval.
Q2: Are there similar patents in countries outside South Korea?
Yes. Similar patents filed in China, Japan, Europe, and the US cover related compounds and methods, forming a broader patent family.
Q3: How does the patent's claims' scope influence infringement risks?
Narrow, specific claims reduce infringement risks but require precise use. Broad claims increase infringement potential but risk invalidation due to prior art.
Q4: What strategies can competitors use to work around this patent?
Design-around by modifying the chemical structure within the scope of patent claims, developing alternative synthesis routes, or targeting different indications.
Q5: When will this patent likely expire, and how does that affect commercialization?
Expires in 2041 unless extended. Market entry strategies should consider patent expiration timelines, especially in markets with similar patents expiring sooner.
