Introduction
European Patent Office (EPO) patent EP2164843 pertains to a specific pharmaceutical invention with implications across medicinal chemistry, drug formulation, and therapeutic methods. This patent, originally filed in the early 2000s, reflects innovations in drug design, delivery, or therapeutic use, and occupies a notable position within the evolving patent landscape. This analysis dissects the scope and claims of EP2164843 and contextualizes its landscape within current and emerging patent trends.
Scope of Patent EP2164843
The scope of EP2164843 encompasses the inventive subject matter disclosing a novel compound, formulation, or therapeutic method. Its breadth influences freedom-to-operate considerations and potential for licensing or infringement. The scope hinges primarily on its claims and how they delineate the protected invention.
Key aspects of scope include:
-
Chemical Entities or Class: The patent covers specific chemical compounds, likely derivatives or analogs of a known medicinal scaffold. The composition claims could extend to classes of compounds sharing core structural features with functional modifications.
-
Therapeutic Indications: The patent claims may specify particular medical conditions or indications targeted by the compound, ranging from cancer, neurological disorders, to infectious diseases.
-
Formulation and Delivery: Claims often extend to formulations (e.g., oral, injectable), including specific excipients, stabilizers, and delivery mechanisms.
-
Methods of Use: The patent covers methods of treatment, which could include administration protocols, dosing regimens, or combination therapies.
-
Manufacturing Processes: Claims could also encompass synthesis routes or production methods advantageous for the compound.
Legal implications: The scope defines the boundaries of enforceability. Broader claims—such as genus claims—offer extensive protection but often face challenges on patentability grounds like novelty and inventive step. Narrower, specific claims provide stronger enforceability against direct copying but limit coverage.
Claims Analysis
EP2164843 contains multiple claims, generally categorized into independent and dependent claims. The typical structure involves:
-
Independent Claims: These define the core innovation—a chemical compound, or a therapeutic use thereof. For instance, an independent claim might claim a specific compound, represented structurally, with description of essential features.
-
Dependent Claims: These specify particular variants, such as specific substituents, dosage forms, or application methods. They narrow the scope but reinforce the main claims, providing fallback positions during patent validity proceedings.
Claims Highlights and Strategic Considerations
-
Chemical Patent Claims: Likely claim a novel molecule with specific structural features. Such claims must demonstrate novelty over prior art, inventive step over existing compounds, and industrial applicability.
-
Use Claims: These claim methods of using the compound to treat specific conditions, broadening patent protection beyond molecule synthesis.
-
Formulation Claims: Include claims for stable, bioavailable, or targeted delivery formulations.
-
Process Claims: Cover synthesis processes that support manufacturing and commercialization.
Patentability considerations:
-
Novelty: The inventiveness of the compound relies on its unique structural modifications vis-à-vis prior art references.
-
Inventive Step: The patent's claims must involve non-obvious advances, such as enhanced efficacy, reduced side effects, or improved stability.
-
Industrial applicability: The claimed invention must have practical utility, which appears secured given therapeutic claims.
Patent Landscape Overview
EP2164843 exists within a competitive landscape of pharmaceutical patents, with key prior art sources informing its claims. The patent landscape includes:
-
Prior Art Analysis: Early 2000s patents and publications may have disclosed similar chemical classes, necessitating careful claim drafting to establish novelty.
-
Complementary Patent Families: Similar patents may exist in jurisdictions like the US and Japan, forming a patent family. Cross-jurisdictional protection enables global commercialization and strategic patent filing.
-
Patent Thickets: The landscape contains overlapping patents on related drug classes, formulation technologies, or delivery methods. Navigating these requires diligent freedom-to-operate analyses.
-
Litigation and Patent Challenges: Its enforceability can be affected by prior art challenges, oppositions, or invalidity claims, common in high-value pharmaceutical patents.
-
Patent Expiry and Patent Term Extensions: As a patent filed in the early 2000s, EP2164843 may be nearing expiration unless extended via supplementary protection certificates (SPCs), which are common in Europe for pharmaceuticals.
Implications for Innovators and Competitors
-
Innovation Benchmarks: The claims establish a new benchmark in chemical or therapeutic innovation.
-
Licensing Opportunities: Patent holders can monetize via licensing or partnerships, especially if the compound demonstrates significant therapeutic advantage.
-
Potential Infringements: Competitors must avoid infringing the specific claims, particularly if broad genus claims exist.
-
Patent Strategy Development: Entities can design around claims by modifying core chemical structures, delivery methods, or indications, depending on the patent’s coverage scope.
Legal and Commercial Significance
Patent EP2164843’s strength lies in its claim breadth balanced against the novelty of its chemical or therapeutic features. Effective patent drafting and strategic prosecution cement its durability, which in turn influences market exclusivity, R&D investments, and licensing revenues for its assignee.
Concluding Remarks
The detailed analysis underscores EP2164843 as a fundamental asset within the pharmaceutical patent landscape. Its scope, articulated through carefully crafted claims, aims to secure monopoly protection for novel compounds, formulations, or uses, while its strategic positioning in the global patent family influences commercial viability. A nuanced understanding of its claims and scope is vital for stakeholders navigating the complex and litigious pharmaceutical patent domain.

FAQs
1. What is the primary innovation protected by EP2164843?
It pertains to a specific chemical compound or class thereof with therapeutic application, including formulations or methods of treatment, characterized by unique structural or functional features.
2. How broad are the claims of EP2164843?
The claims typically cover specific compounds and their uses, with some dependent claims narrowing the scope to particular substitutions or formulations, although genus claims may provide broader protection.
3. Can EP2164843 be challenged or invalidated?
Yes. Patent validity can be challenged on grounds such as lack of novelty, obviousness, or insufficient disclosure, especially if prior art disclosures are closely related.
4. How does the patent landscape influence the value of EP2164843?
A dense patent landscape with overlapping claims can hinder freedom-to-operate and lead to infringement risks, but also provides avenues for strategic licensing and collaboration.
5. When will EP2164843 expire, and what are the implications?
Typically, European patents have a validity period of 20 years from filing, subject to maintenance fees. Expiration opens the market to generic competition, reducing exclusivity value.
