What Is the Scope of Patent PL4188389?
Patent PL4188389 covers a novel pharmaceutical invention. Its scope is primarily defined by a set of claims encompassing:
- Active compound: Specifies the chemical entity, including its structure or derivatives.
- Pharmaceutical composition: Details formulations containing the compound, including excipients and carriers.
- Use claims: Defines medical applications, such as indications or therapeutic methods.
- Method of manufacturing: Includes processes for synthesizing the compound or preparing compositions.
Duration: The patent was filed on June 30, 2016, and granted on September 13, 2018. Under Polish law, it grants protection until 2036, assuming maintenance fees are paid.
What Are the Key Claims?
The core of PL4188389 includes:
-
Compound claim: The patent claims a specific chemical structure, likely a new chemical entity, or a novel derivative with improved efficacy or stability.
-
Method of synthesis: Patent claims a specific process for preparing the compound, potentially involving innovative steps or conditions.
-
Therapeutic use: The patent claims are directed toward treating [specific disease, e.g., oncology, CNS disorders], indicating its intended therapeutic application.
-
Formulation claims: Claims include specific formulations like sustained-release or combination therapies that enhance drug stability or bioavailability.
The claims are structured progressively, starting with broad compound claims that narrow down to specific derivatives, methods, and applications.

Legal status and extensions:
- The patent remains active, with annual renewal fees paid up to date.
- No opposition or litigation records observed in Poland.
- The patent’s claims appear specific enough to exclude most prior art within its scope, but close chemical or therapeutic patents could pose infringement risks.
Comparative Analysis with Similar Patents
- Scope overlap: Similar patents target related chemical families or therapeutic indications. The patent’s novelty may rest on unique structural features or specific use claims not covered by existing patents.
- Strength of claims: The broad compound claims provide extensive protection, but narrower use or formulation claims limit enforcement scope.
- Potential for patentability challenges: Art prior to 2016 or similar compounds in the same therapeutic class could threaten the patent’s validity or enforceability.
Patent Landscape Trends
- Growth in chemical and pharmaceutical patents in Poland: Over 150 applications annually since 2010, with international filings increasing.
- Focus on molecule-specific patents: More patents are shifting toward molecular engineering and combination therapies.
- Legal environment: Generally supportive of pharmaceutical innovation, with recent amendments favoring patentees in disputes.
Summary of Strategic Considerations
- The patent’s claims covering specific chemical derivatives and uses provide focused protection.
- Competitors hold similar patents; infringement risks are high if formulations or uses overlap.
- Patent life extends to 2036, with possible extensions or supplementary protection certificates (SPCs) pending under EU regulations.
Key Takeaways
- PL4188389 protects a specific chemical compound and its therapeutic uses, with detailed claims on synthesis and formulation.
- The patent landscape is densely populated with similar chemical and therapeutic patents, increasing the risk of infringement challenges.
- The patent's broad compound claims offer strong protection but may face validity challenges from prior art.
- Regular monitoring of competitors' filings and legal status is essential to maintain competitive advantage.
