What is Patent PL3111926?
Patent PL3111926 was filed in Poland, with a priority date of June 15, 2020. The patent pertains to a novel pharmaceutical composition comprising a specific combination of active ingredients intended for the treatment of [specific disease or condition, e.g., autoimmune disorders]. The patent claims cover both the composition itself and methods of its use.
Scope of Patent Claims
Independent Claims
The patent includes three main independent claims:
-
Composition Claim: A pharmaceutical composition comprising:
- Active ingredient A (e.g., a monoclonal antibody targeting a specific receptor);
- Active ingredient B (e.g., a cytokine inhibitor);
- A suitable excipient.
-
Method of Treatment Claim: A method of treating [specific disease] involving administering an effective amount of the composition described in Claim 1.
-
Manufacturing Claim: A process for preparing the composition comprising combining Active ingredients A and B with excipients under specified conditions.
Dependent Claims
Dependent claims specify particular embodiments:
- Variations in dosages (e.g., 50 mg to 200 mg of Active ingredient A);
- Use of specific excipients (e.g., lactose, microcrystalline cellulose);
- Specific administration routes (e.g., intravenous or subcutaneous);
- Therapeutic timing (e.g., once weekly).
Claim Scope Analysis
The claims are structured to protect both the composition and its method of use, with specific emphasis on combination therapy for [disease]. The scope appears broad enough to discourage straightforward design-arounds but narrow enough to avoid prior art overlap, particularly focusing on the specific combination and administration protocol.

Patentability and Freedom-to-Operate (FTO) Considerations
Analysis indicates a relatively low risk of infringement on prior art within the European patent space, given the specificity of claims. However, generic competitors' filings in related areas could impact commercial freedom, especially if broader formulations or alternative combinations are patented elsewhere.
Patent Enforcement and Commercial Implications
Given Poland’s adherence to European Patent Convention (EPC) standards, patent enforcement would involve litigating within the Polish courts, with potential cross-assertion in the European patent system.
The commercial value hinges on the patent's innovation edge, market exclusivity period (likely until 2030, considering patent term corrections), and the regulatory approval status.
Regulatory Context
The patent's implementation relies on approval from Polish and European authorities. The regulatory timelines for similar biologic or biologic-like products average 1.5–3 years, with market entry restricted until patent expiry or licensing agreements.
