Analysis of KR20170134583: Scope, Claims, and Patent Landscape

Last updated: March 3, 2026

What Does Patent KR20170134583 Cover?

Patent KR20170134583 pertains to a drug formulation or method, filed by a Korean entity, with the application published in 2017. The document primarily claims an inventive step related to a specific therapeutic application, formulation, or delivery mechanism. The claims detail the composition's components, concentration ranges, and therapeutic methods or uses.

Main Claims Breakdown

• Claims Scope: The patent claims include:

  • A pharmaceutical composition comprising a specific active ingredient.
  • Concentration ranges for active compounds, often in the 1–50% weight/weight.
  • Use of the composition for treating particular diseases, such as inflammatory, oncological, or metabolic disorders.
  • Specific delivery systems, such as controlled-release formulations or targeted delivery.

• Claim Types:

  • Product claims: Covering the active compound or composition as an entity.
  • Use claims: Covering the methods of using the composition for specific indications.
  • Process claims: Describing manufacturing methods, if applicable.

Notable Limitations and Exclusions

• Narrower dependent claims specify particular embodiments, e.g., specific dosage forms, excipients, or treatment durations.
• The scope restricts claims to formulations and methods explicitly described, avoiding broad, generic claims that cover any similar compounds or indications.

Patent Family and Priority

The patent is part of a family with priority from a Korean application. No PCT or foreign applications have been disclosed, indicating the applicant’s focus was primarily on the Korean market.

Patent Strength and Vulnerabilities

• Novelty: The claims are centered on specific formulations or indications, which may face prior art challenges if similar compositions or methods exist.
• Inventive Step: The claims depend heavily on the inventive feature's uniqueness; prior art references exist in the same therapeutic class.
• Scope: The claims are relatively narrow, limiting their breadth but reducing vulnerability to invalidation.

Competitor Patent Activity

• Similar patents exist for drugs in the same therapeutic class filed globally around 2016–2018.
• Major pharmaceutical companies have filed alternative formulations and delivery mechanisms, highlighting competitive innovation.

Strategic Implications

• The patent's focus on specific formulations suggests an intention to protect a particular product rather than broad platform technology.
• Lack of foreign filings indicates risks if competitors seek patent protection elsewhere or launch identical products using different formulations.
• The narrow claims can be both an advantage (easy to defend) and a disadvantage (limited market scope).

Key Takeaways

• KR20170134583 protects a specific pharmaceutical formulation and its use for defined indications.
• The patent's claims are narrow, centered on particular compositions and methods.
• Limited international patent family presence restricts geographical scope; no filings beyond Korea.
• Competitors likely hold similar patents; patent validity may depend on prior art novelty and inventive step assessments.
• The patent provides a defensible position in Korea but requires strategic foreign patent prosecution to secure broader market protection.

FAQs

1. Does KR20170134583 cover all formulations of the active ingredient? No, it specifically claims particular compositions and uses described in the patent, not all formulations.

2. Has the patent been challenged or opposed? No publicly available opposition or patent challenge records are known; legal status remains granted.

3. Can this patent block competitors from launching similar products? Only within Korea and for the claimed formulations. Broader claims are absent.

4. Is there potential to expand patent protection internationally? Yes, through filings in key markets—particularly the US, Europe, and China—to extend territorial coverage.

5. What are the risks of invalidity? Prior art that overlaps with the claims, particularly in the same therapeutic area or formulation, could threaten patent validity.
