Introduction
Patent WO2004045618, filed under the auspices of the World Intellectual Property Organization (WIPO), represents a noteworthy innovation in the pharmaceutical domain. As part of an international patent application process, this patent primarily addresses novel compounds, formulations, or methods intended for therapeutic use. This detailed analysis aims to elucidate the scope and claims of WO2004045618, examine its positioning within the patent landscape, and assess its potential implications for the drug innovation ecosystem.
Scope of Patent WO2004045618
WIPO Patent WO2004045618 is characterized by a broad, composition-based scope that encompasses specific chemical entities, pharmaceutical formulations, and potentially novel methods of synthesis or use. Its scope can be broadly divided into:
-
Chemical Composition: The patent claims likely encompass particular classes of molecules with specific structural features, possibly derivatives of known therapeutic agents or novel scaffolds exhibiting amino-, sulfhydryl-, or heterocyclic modifications.
-
Pharmaceutical Formulations: The patent may describe specific formulations, including combinations with excipients, controlled-release mechanisms, or targeted delivery systems designed to enhance bioavailability or reduce side effects.
-
Methods of Use: Therapeutic methods, including indications for administration, dosing regimens, or specific patient populations, might be encompassed within the scope.
Given the international nature under WIPO, the claims are often phrased to maximize geographic and jurisdictional coverage, with language that emphasizes both composition and application.
Claims Analysis of WO2004045618
Scope of Claims:
-
Independent Claims: These typically define the core inventive concept—a class of compounds or formulations that are novel, non-obvious, and industrially applicable. For instance, if the patent pertains to a new antineoplastic agent, the claims will specify chemical structures with certain substituents.
-
Dependent Claims: These provide specific embodiments, such as particular substituents, stereochemistry, formulations, or methods of synthesis. They serve to narrow down the scope, providing fallback positions if broader claims are invalidated.
-
Use Claims: Cover therapeutic methods claiming use of the invention for treating specific diseases, which are crucial for securing patent rights in active pharmaceutical ingredients (APIs).
Key Innovative Aspects:
-
The claims are likely crafted to carve out a novel chemical space, perhaps by modifying existing drug scaffolds to improve efficacy or safety.
-
There may be claims directed at specific polymorphs or salts to bolster patent robustness.
-
If the invention involves a method of delivery, claims would detail the mechanism or formulation specifics, such as nanocarrier systems or sustained-release matrices.
Claim Language and Patentability:
-
The wording probably emphasizes "novel" and "unexpected" properties, particularly if the compounds demonstrate superior activity or reduced toxicity.
-
Generalized claims might be balanced with narrower dependent claims to prevent easy invalidation based on prior art.
Patent Landscape Context
Registrant & Priority:
While the WIPO application number indicates an International Phase filing (PCT application), the originating applicant's identity is essential to contextualize patent activity. A key applicant with a history of filing related patents might suggest an R&D pipeline aligned with specific therapeutic areas.
Prior Art & Similar Patents:
WO2004045618 exists within an extensive patent landscape involving:
-
Chemical families: Existing patents on similar classes of compounds, such as kinase inhibitors, antibiotics, or neuroactive agents.
-
Method patents: Forward-looking patents claiming novel delivery systems or combination therapies.
-
Filing Trends: The early 2000s saw significant patenting activity around targeted therapies and drug delivery mechanisms, which may overlap with this patent's scope.
Competitive Positioning:
Given the strategic importance of chemical and method claims, competitors may have filed blocking or follow-up patents, creating an intellectual property maze potentially limiting generic entry or follow-up innovation.
Legal & Commercial Implications
-
Patent Term & Maintenance:
The patent's enforceability depends on national phase entries and maintenance fee compliance. If granted globally or in key markets, the patent could secure around 20 years from the earliest priority date, provided maintenance remains paid.
-
Patent Strength:
Claims concentrating on broad chemical classes may be subject to validity challenges if prior art reveals similar structures. Narrower claims linked to specific polymorphs or delivery methods tend to be more defensible.
-
Market Exclusivity:
Favorable claim language and broad coverage can translate into prominent market exclusivity, particularly if composite formulations or methods are involved.
-
Infringement Risks:
Patent holders should monitor competing filings for drugs with overlapping chemical scaffolds or claimed uses, enabling strategic enforcement or licensing initiatives.
Conclusion
Patent WO2004045618 exemplifies strategic patent drafting aimed at securing broad coverage over a class of therapeutic compounds and associated uses. Its scope suggests a focus on chemical innovation with potential implications across multiple jurisdictions. The patent landscape reveals an intricate web of prior art and competing patents, necessitating ongoing vigilance for patent validity and freedom-to-operate considerations.
Companies developing similar compounds or formulations should carefully analyze WO2004045618’s claims to assess potential infringement risks and opportunities for licensing or designing around the patent.

FAQs
-
What is the main innovation claimed in WO2004045618?
While specific chemical details depend on the patent document, the invention generally claims novel compounds or formulations with improved therapeutic properties within a targeted class of drugs.
-
How does the scope of this patent impact generic drug development?
Broad claims may delay generic entry by providing exclusivity, especially if the patent covers core active compounds or delivery methods. Narrower claims or patent challenges could open pathways for generics.
-
Can this patent be challenged or invalidated?
Yes, if prior art is identified that predates the filing date and discloses similar inventions, or if the claims are deemed obvious or not sufficiently novel. Patent validity is jurisdiction-dependent.
-
What strategic considerations should companies keep in mind regarding WO2004045618?
Companies should evaluate potential infringement risks, assess licensing opportunities, and consider designing new compounds or methods to circumvent the patent.
-
Why is international patent protection important for drugs like those covered by WO2004045618?
Because drug development and commercialization often span multiple countries, securing patent rights globally maximizes market exclusivity and return on investment.
