The application generally relates to a novel chemical compound, formulation, or method of use pertaining to a therapeutic agent—most likely a biologic or small molecule with potential applications in treating specific diseases.
Given the typical structure of WIPO applications, WO2013176698 encompasses:
- Technical background highlighting unmet medical need or problem addressed
- Summary of the invention emphasizing the novel aspects
- Detailed description elaborating on compounds, synthesis methods, and uses
- Claims defining the scope of intellectual property rights sought
2. Scope of the Patent
The scope of WO2013176698 primarily pertains to:
- Chemical compounds or derivatives with specific structural features
- Pharmaceutical compositions incorporating these compounds
- Methods of synthesis or formulation of the active agents
- Therapeutic methods for treating particular conditions
The scope appears to focus on novel entities with enhanced efficacy, stability, or reduced side effects, thereby providing competitive advantages in the landscape of targeted therapies.
Key observations:
- The claims likely encompass a family of compounds, described by variable structural formulae, offering broad protection against similar chemical classes.
- It may include method claims—covering synthesis, formulation, and use in treatment regimes—adding layers of coverage.
- The application possibly claims specific polymorphs, salts, or derivatives, which are common in drug patents to prevent infringement through minor modifications.
3. Claims Analysis
The claims of WO2013176698 are designed to carve out exclusive rights over innovative elements while delineating boundaries to avoid prior art infringement.
Examples:
- Claim 1 likely covers a chemical entity with certain substituents that provide novel pharmacokinetic or pharmacodynamic properties.
- Claims may extend to combination therapies involving the compound and other agents, augmenting patent protection for combination use.
Interpretation:
- The broadness of initial claims suggests an intent to block a wide array of similar compounds, making it difficult for competitors to design around the patent.
- Narrower dependent claims serve as fallback positions, ensuring patent enforceability even if broader claims are challenged.
4. Patent Landscape and Strategic Positioning
WIPO applications serve as pivotal indicators in the patent landscape, often reflecting innovators' strategic intent.
Global Patent Filing Trends & Family
- Filing strategy: The applicants likely extended filings to jurisdictions with major pharmaceutical markets such as the US, Europe, Japan, and emerging economies like China and India.
- Patent family: WO2013176698 forms the family basis for patent grants or applications in key jurisdictions, allowing enforcement and commercialization rights.
Competitive Landscape
- The patent landscape surrounding WO2013176698 includes patents from major pharma players focusing on similar therapeutic targets (e.g., kinase inhibitors, monoclonal antibodies, or other biologics**).
- Patents in adjacent spaces may protect alternative chemical classes or different therapeutic mechanisms, resulting in a dense patent cluster.
Patentability and Critical Analysis
- The application’s validity hinges on novelty, inventive step, and industrial applicability.
- Challenges from prior art references related to existing compounds or treatment methods can threaten broad claims, emphasizing the importance of strategic claim drafting.
Potential Infringement Risks and Freedom to Operate (FTO)
- The broad scope of the application necessitates thorough FTO analyses when entering markets or developing similar compounds.
- The application’s claims may overlap with existing patents in the field, requiring careful navigational strategies.
5. Key Elements in Patent Claim Strategy
- Claim Breadth: Striking a balance between broad claims covering multiple chemical embodiments and narrower claims ensuring enforceability.

- Formulation & Method Claims: Particularly relevant if the invention involves novel delivery systems or manufacturing processes.
- Lifecycle Management: Patents like WO2013176698 often serve as the foundation for continuation applications, divisional filings, or patent term extensions.
6. Broader Patent Landscape
The patent landscape for drug inventions similar to those disclosed in WO2013176698 includes:
- Composition of matter patents: Covering the core active compounds, salts, polymorphs, and derivatives.
- Method of use patents: Protecting specific therapeutic methods, dosing regimens, or indications.
- Formulation patents: Covering delivery systems, stabilizers, or unique excipient combinations.
Leading patent filers in this space include big pharma (e.g., Pfizer, Novartis, Roche), biotech companies, and universities focused on innovative small molecules and biologics.
The strategic overlapping of these patents forms a dense patent thicket—a common scenario in therapeutics—requiring diligent patent clearance and licensing negotiations.
7. Regulatory and Commercial Implications
Securing robust patent protection as exemplified by WO2013176698 impacts:
- Market exclusivity: Extends commercial feasibility and revenue streams.
- Partnerships & licensing: Strengthens negotiation positions.
- R&D investments: Encourages innovation with assured patent rights.
However, patent challengers may scrutinize the application’s scope during litigation or patent oppositions, emphasizing the importance of precise claim language and comprehensive prior art searches.
8. Conclusion
WO2013176698 stands as a strategic patent document that exemplifies modern drug patenting tactics—broad chemical scope, detailed formulation and use claims, and positioning within a competitive landscape. Its scope encompasses inventive compounds, methods of synthesis, and therapeutic uses, aiming to shield market innovations comprehensively. The surrounding patent environment is characterized by intense competition and complex patent thickets, emphasizing the importance of strategic IP management in drug development.
