Patent Overview
Patent Number: WO2005032517
Application Publication Date: April 28, 2005 (publication of international application)
Applicants/Inventors: A consortium of research entities likely focusing on novel therapeutic compounds, specific identity details dependent on regional filings.
Field: Pharmaceutical compounds, potentially targeting novel therapeutic pathways or formulations.
This international patent application, under the Patent Cooperation Treaty (PCT), is designed for broad territorial coverage, seeking patent protection in multiple jurisdictions. The goal: securing exclusive rights to a novel drug candidate or composition of matter with potential medical efficacy.
Scope of the Patent
Targeted Therapeutic Domain
The patent primarily pertains to the invention of novel chemical entities or formulations capable of therapeutic application. Its scope encompasses:
- New chemical compounds: including derivatives, salts, and analogs.
- Pharmacological use: specifically related to treating certain diseases or conditions.
- Preparation methods: for the synthesis of these compounds.
- Formulation and delivery systems: designed to optimize bioavailability, stability, or targeted delivery.
This breadth ensures coverage of the compound itself, its derivatives, or related pharmaceutical compositions, fostering comprehensive patent protection within the drug development pipeline.
Claims Focus
The core claims are centered around:
- Chemical structure claims: defining the novel compounds with specific structural features.
- Use claims: specific medical indications or therapeutic methods utilizing the compounds.
- Process claims: methods of synthesizing or formulating the compounds.
The claims exhibit a layered architecture, with independent claims capturing the broadest definitions and dependent claims narrowing down specific embodiments.
Analysis of Key Claims
1. Chemical Compound Claims
- Structural Scope: Claims describe compounds with a core skeleton, possibly involving heterocycles, aromatic groups, or side chains conferring pharmacological activity.
- Limitations and Variants: Definitions include various substituents, permissible modifications, or isomers, allowing the claims to encompass a wide gamut of related molecules.
2. Therapeutic Use Claims
- Disease Targeting: Claims specify the use of the compounds for conditions such as cancers, inflammatory diseases, or neurological disorders, depending on the applicant’s focus.
- Method of Treatment: The claims extend to administering effective amounts of the compounds for the identified indications, covering both single and combination therapies.
3. Process Claims
- Synthesis Methods: Claims detail steps for preparing the compounds, including reaction conditions, catalysts, or purification techniques.
- Formulation Claims: Cover preparation of stable compositions, possibly including excipients, delivery vehicles, or sustained-release systems.
Claim Strategy
The claims are structured to balance breadth and specificity:
- Broad independent claims maximize coverage of chemical classes and uses.
- Narrow dependent claims provide fallback positions and cover specific embodiments.
- This multidimensional approach fortifies patent strength against challenges and enhances licensing opportunities.
Patent Landscape and Competitive Position
Global Patent Families and Jurisdictional Coverage
WO2005032517, as a PCT application, lays the groundwork for territorial filings, including:
- European Patent Office (EPO)
- United States Patent and Trademark Office (USPTO)
- Japan Patent Office (JPO)
- Chinese Patent Office (SIPO)
- Other national patent offices
The patent’s broad claims increase the likelihood of national phase entries, effectively creating a comprehensive protective shield for the claimed molecules and applications.
Related Patent Families and Prior Art
- Preceding patents: may include earlier disclosures of similar chemical scaffolds or therapeutic methods.
- Follow-up patents: likely encompass improved formulations, delivery systems, or extended indications, thereby creating a patent family ecosystem around the core invention.
Patent landscape analyses indicate that similar compounds or mechanisms are often patented by competitors such as Pfizer, Novartis, or emerging biotech entities, leading to a densely crowded patent space.
Litigation and Licensing Trends
Given the strategic importance, key insights include:
- Potential patent disputes: especially around overlapping chemical structures or claims.
- Licensing opportunities: especially in markets where the patent confers exclusivity.
- Challenges: from generic manufacturers or patent examiners contesting the validity of broad claims.
Legal Status and Validity
The patent's legal standing is influenced by:
- Grant status: Confirmed or pending approval in key jurisdictions.
- Oppositions or litigations: If any oppositions or invalidation suits are filed, they could impact enforceability.
