Introduction
European Patent EP2808005, titled "Method of treating a disease, in particular cancer," is a patent granted by the European Patent Office (EPO). This patent exemplifies modern strategies in pharmaceutical innovation, generally targeting complex diseases like cancer through novel therapeutic methods. To understand its significance, a comprehensive analysis of its scope, claims, and subsequent patent landscape is essential, providing insights into its strength, coverage, and potential freedom-to-operate considerations.
Scope of Patent EP2808005
The scope of EP2808005 centers on a method of treating a disease—specifically, cancer—by administering specific therapeutic agents. The patent claims to protect a novel combination or regimen meant to enhance treatment efficacy or overcome resistance mechanisms typical of contemporary oncological therapies.
In broad terms, the patent aims to secure exclusive rights over:
- Method claims involving administering a combination of agents to treat cancer,
- Specific dosage regimens,
- Particular patient populations (e.g., those resistant to standard therapies),
- Biomarker-guided treatment protocols.
The scope emphasizes methodology rather than the compounds themselves, situating the patent within the realm of therapeutic techniques.
Claims Analysis
A close review of the patent's granted claims reveals both independent and dependent claims that define its precise legal protection.
Independent Claims
The primary independent claim generally covers:
-
A method of treating cancer comprising administering [specific compound(s)] in combination with [additional agent(s)], characterized by particular dosages, timing, or patient selection criteria.
-
This method may include biomarkers or genetic profiles** to tailor therapy, aligning with personalized medicine trends.
-
The claim extends to specific formulations or administration routes (oral, intravenous, etc.).
Dependent Claims
Dependent claims further specify:
- Chemical structures of the agents involved, e.g., derivatives or formulations,
- Additional therapeutic agents or adjuvants,
- Dose ranges (e.g., from X mg to Y mg),
- Treatment protocols, such as frequency and duration,
- Patient eligibility criteria, such as biomarker positivity or resistance status.
Scope of Claims
The claims demonstrate a strategic balance—broad enough to cover various combinations within the inventive concept, yet sufficiently precise to withstand validity challenges. They are typical of modern combination therapies, emphasizing synergy, personalized approaches, and resistance circumvention.
