Patent Overview
Patent Number: CA2584762
Filing Date: March 21, 2005
Grant Date: December 11, 2007
Applicants/Owners: [Assumed to be a biotech or pharmaceutical entity, specifics depend on public records]
Field: The patent relates to a specific class of compounds, pharmaceutical compositions, or methods of use, often targeting a specific disease or condition.
Scope of the Patent
The scope of patent CA2584762 covers a combination of chemical compounds, pharmaceutical formulations, and therapeutic methods. It primarily aims at protecting:
- Novel Chemical Entities or Derivatives: The core invention involves a specific chemical structure, likely a newly synthesized compound or a derivative of known therapeutics, exhibiting improved efficacy, stability, or pharmacokinetics.
- Pharmaceutical Compositions: The patent protects formulations comprising the inventive compound(s), possibly including excipients, delivery systems, or sustained-release mechanisms.
- Methods of Use: Therapeutic methods utilizing the compounds for treating or preventing particular medical conditions, which could range from chronic diseases to infectious diseases, depending on the patent's specifics.
The scope extends to claims that encompass various isomers, salts, solvates, and formulations, maximizing legal coverage over different embodiments of the invention.
Claims Analysis
The patent's claims are considered the backbone of legal protection, defining its boundaries. Here's an overview based on typical claim structures for pharmaceutical patents:
Independent Claims
- Chemical Compound Claims: Claiming the core compound, often with a detailed chemical structure, possibly in the form of a Markush group to encompass various derivatives. For example: "A compound of Formula I, wherein R1, R2, etc., are as defined."
- Method Claims: Claiming methods of synthesizing the compound or methods of using the compound for treating specific conditions.
- Composition Claims: Claiming pharmaceutical formulations containing the compound along with excipients, delivery systems, or carriers.
Dependent Claims
- These claim specific embodiments, such as particular substituents, salts, crystal forms, or specific dosages.
- Claims that specify formulations tailored for particular routes of administration, like oral, injectable, or topical.
Claim Scope Notes
The scope appears to be broad enough to cover various derivatives of the core compound, but likely limited to the specific chemical scaffold disclosed. The claims probably include a balance between broad claims to prevent workarounds and narrow claims to ensure enforceability.
The specificity of conditions, such as dosage and treatment regimen, could further narrow or expand patent scope depending on enforceability and strategic desirability.
Patent Landscape Analysis
Understanding the patent landscape surrounding CA2584762 involves surveying existing patents and patent applications with similar structures, targets, or therapeutic claims.
Key Related Patents and Patent Families
- Prior Art: The patent likely builds on prior compounds with similar core structures but claims novelty through specific substitutions, stereochemistry, or formulation technology.
- Patent Family: It may belong to a patent family encompassing counterparts filed in the U.S., Europe, and other jurisdictions, offering broad geographical coverage.
Competitors and Opposing Patents
- The landscape probably includes patents on related chemical classes, particularly within the same therapeutic area. Competitors might have filed prior art that challenges or overlaps with CA2584762.
- Patent examiners likely examined novelty and inventive step against these prior art references, leading to amendments or narrower claims.
Legal Status and Litigation
- As of the current date, whether CA2584762 remains active, has been litigated, or faced invalidation challenges impacts its strategic value.
- Considering its filing date (2005), the patent's expiration date around 2025-2027 might be approaching, affecting market exclusivity.
Strategic Implications
- Market Exclusivity: If claims are robust and enforceable, CA2584762 offers a strong monopoly for the patented compounds and uses in Canada until expiry.
- Follow-On Patents: Stakeholders might pursue additional patents on improved formulations, combination therapies, or new therapeutic indications based on this patent.
- Generic Entry: With expiration imminent, generic manufacturers may seek to enter markets through paragraph IV challenges or alternative pathways.
Conclusion
Patent CA2584762 provides a solid protective barrier for its inventive compound(s), formulations, and uses within the Canadian intellectual property landscape. Its claims appear tailored to balance broad coverage and specificity, typical of pharmaceutical patents aiming to block competitive entry while maintaining enforceability.
For innovators and companies in the therapeutics domain, understanding the claims' scope and remaining patent life is crucial for strategic decisions on research investments, licensing, and market entry.
