Publication Number: WO2011089183
Application Date: January 24, 2011
Priority Data: Claims priority from earlier applications, including a French application (FR1051160).
Inventors: Listed inventors suggest a focus on medicinal chemistry, pharmaceutical formulations, or targeted therapeutics.
Applicants: Often linked to biotech firms or pharmaceutical entities pursuing drug candidates with specific unmet medical needs.
This patent generally claims novel compounds, pharmaceutical compositions, and potential methods of treatment involving these compounds.
Scope of the Patent
The scope of WO2011089183 encompasses the chemical nature of specific compounds, their pharmaceutical formulations, and their therapeutic use.
Claims Overview
The document contains a mixture of primary and dependent claims, encompassing the following core elements:
-
Chemical Entities: The patent primarily covers specific chemical compounds, likely derivatives or analogs of known pharmacophores, tailored for therapeutic purposes. These compounds are characterized by particular substituents, stereochemistry, or functional groups as detailed in the claims.
-
Pharmaceutical Compositions: Claims extend to preparations containing these compounds, including dosage forms, excipients, and carriers suitable for administration.
-
Therapeutic Methods: The patent claims methods of treating specific diseases, often associated with the biological targets or pathways where the compounds demonstrate activity (e.g., kinase inhibition, receptor modulation).
-
Uses and Formulations: Claims also cover the use of these compounds in various medical indications, potentially spanning from oncology to autoimmune diseases, depending on the disclosed biological activity.
Detailed Analysis of the Claims
1. Chemical Compound Claims
The core claims specify novel chemical structures, often represented by a formula with variable groups (R1, R2, etc.), covering a class of compounds rather than a single molecule. These claims are intended to be broad enough to encompass various derivatives, but sufficiently specific to distinguish from prior art.
2. Pharmaceutical Composition Claims
Inclusion of claims directed to compositions containing the compounds, including possible combinations with other active agents, excipients, and delivery systems. These claims enhance commercial scope by covering formulations for different routes of administration (oral, injectable, topical).
3. Method of Use Claims
Claims that focus on therapeutic methods for treating particular illnesses, leveraging the activity spectrum of the compounds. Shape the patent's utility by claiming treatment of diseases such as cancer, neurodegenerative disorders, or infectious diseases—depending on the pharmacological profile.
4. Diagnostic and Biomarker Claims
If present, claims related to biomarkers or diagnostic methods linked with the compounds' mechanism of action, potentially broadening scope beyond drugs to include companion diagnostics.
Strategic Significance of the Claims
The claim strategy aims to secure a broad protective umbrella covering chemical space, therapeutic applications, and formulations, which is critical for defending market position against generic challenges or prior art. The inclusion of method claims further postures the patent as a tool for controlling treatment protocols involving these compounds.
Broad chemical claims typically offer significant leverage, provided they are well-supported by the detailed description and examples. Narrow claims risk easy circumvention but offer more targeted protection.
Patent Landscape Analysis
1. Related Patent Families and Prior Art
The patent belongs to a landscape involving chemical entities and their pharmaceutical uses. Key areas around this patent typically include:
- Chemical Analog Patents: Compounds with similar core structures, possibly disclosed in prior art.
- Method of Treatment Patents: Covering therapeutic applications of related compound classes.
- Formulation Patents: Covering specific delivery methods or combinations.
2. Competitor and Patent Environment
Numerous patents in the domain of small-molecule inhibitors, biological agents, or personalized therapeutics may be relevant. Patent databases, such as Patentscope (for WIPO filings), Espacenet, and USPTO, identify prior art that can challenge or support patent validity or freedom-to-operate analyses.
3. Geographic Scope and Patent Families
Given its WIPO publication status, WO2011089183 benefits from international coverage under the Patent Cooperation Treaty (PCT), aiming for national phase entry across multiple jurisdictions such as the US, Europe, Japan, China, and others. Strategic filing broadens protection and deters competitors.
4. Patent Litigation and Enforcement Risks
The scope's breadth influences litigation strategies. Broad chemical claims risk invalidation if prior art discloses similar structures; narrow claims might risk limited enforceability but reduce invalidation risk.
Patentability and Validity Considerations
The patent’s claims must demonstrate synthetically feasible compounds, unexpected therapeutic advantages, and inventive step over existing art. The description’s experimental evidence supporting bioactivity or novelty influences enforceability.
Notably, complex chemical structures require meticulous drafting to shield against prior disclosures. The inventive step hinges on the structural modifications providing unexpected benefits, such as increased potency, reduced toxicity, or novel activity profiles.
Implications for Industry Stakeholders
Pharmaceutical Innovators:
Understanding claim scope guides research strategies, enabling focus on unclaimed chemical space or functional aspects.
Patent Filers and Attorneys:
Analyzing claim language, scope, and supporting disclosures aids in drafting robust patents and in navigating freedom-to-operate assessments.
Licensees and Generics Firms:
Identifying patent extents informs licensing negotiations or designing around strategies.
Key Takeaways
- Scope is centered on specific chemical compounds with therapeutic utility, with claims encompassing compositions and methods.
- Claims' breadth balances innovation protection and risk of invalidation; precise language strengthens enforceability.
- Patent WO2011089183 resides within a complex landscape of chemical, therapeutic, and formulation patents, requiring comprehensive landscape mapping for strategic decisions.
- International filing under WIPO’s PCT broadens geographical protection, reinforcing market defense and licensing opportunities.
- Continuous monitoring of related prior art and legal developments remains imperative to optimize patent strategy and drug development pipelines.
FAQs
1. What types of compounds are covered under WO2011089183?
The patent covers novel chemical structures, likely derivatives or analogs of a core pharmacophore, designed for therapeutic purposes, with specific substitutions and stereochemistry detailed in the claims.
2. How broad are the claims, and what does that mean for competitors?
The claims are structured to cover a range of related compounds and uses, offering significant protection but may be challenged if prior art discloses similar molecules. Their breadth dictates enforcement strength and potential for licensing.
3. How does this patent fit into the global drug patent landscape?
Its international PCT status allows protection across multiple jurisdictions, positioning it strategically in the global pharmaceutical market landscape for drugs targeting specific diseases.
4. Can the scope of claims be challenged through legal means?
Yes; validity challenges based on prior art or non-obviousness can potentially weaken the patent’s enforceability if prior disclosures are found to cover the claimed subject matter.
5. What strategic steps should patent holders consider?
They should continuously monitor patent landscapes, file continuations or divisional applications to adapt scope, and consider clinical efficacy evidence to reinforce patent claims.
