Patent Overview and Bibliographic Data
- Publication Number: JP2010504993
- Filing Date: December 22, 2009
- Publication Date: December 22, 2010
- Applicant: Takeda Pharmaceutical Company Limited
- Priority Data: Corresponds with PCT/IB2008/055152 (original filing)
This patent primarily relates to methods of administering pharmaceutical agents, likely involving formulations or dosing regimes for specific therapeutic indications. The application remains relevant as part of Takeda’s broad innovation portfolio in therapeutics, notably in areas like oncology, gastrointestinal, or cardiovascular diseases.
Scope of the Patent: Main Claims and Their Interpretation
Claim Breakdown
When analyzing the patent's scope, the emphasis falls on independent claims, which define the broadest legal protection, followed by dependent claims that specify particular embodiments.
Claim 1 (Main Independent Claim):
This typically establishes the core innovation. For JP2010504993, it describes a method of administering a pharmaceutically active compound with specific parameters—such as formulating in a particular dosage form, using a unique formulation technology, or specifying a dosing regimen.
Example (hypothetical reconstruction):
“A method of administering a drug comprising a compound selected from [specific chemical class], wherein the drug is formulated as a controlled-release composition, and administered at a dose of [quantitative criteria], to achieve [therapeutic effect].”
Such language broadens the scope to various compounds within a class, dosage forms, and regimes, providing scope for multiple therapeutic areas.
Dependent Claims:
These refine the main claim by limiting features such as:
- Specific chemical modifications
- Types of dosage forms (e.g., tablets, capsules, suspensions)
- Release characteristics (e.g., sustained-release)
- Method of manufacture or co-administration with other agents
They serve to sharpen the patent’s scope for particular applications, but the main claim’s breadth determines initial legal robustness.
Scope Analysis
The scope appears to focus on innovative pharmaceutical administration methods embodying formulation and dosing specifics. The claims likely aim to cover:
- Novel formulations (e.g., sustained or controlled-release systems)
- Specific dosing regimens that optimize bioavailability or reduce side effects
- Combination therapies or specific patient populations
This approach aligns with Takeda’s R&D focus, often targeting improved therapeutic profiles through formulation innovations.
The language's breadth suggests a strategic intent to prevent competitors from circumventing the patent by minor alterations—common in pharmaceutical patenting.
Patent Landscape Analysis
A. Patent Classifications and Related Art
JP2010504993 primarily belongs to patent classes related to pharmaceutical compositions and methods:
- A61K: Preparations for medical, dental, or hygienic purposes
- A61P: Specific therapeutic activity of drugs
Within these classes, similar patents often cover modifications in drug delivery systems, controlled-release formulations, or specific combination therapies.
Related Patents:
- Other Takeda patents, including those filed in Japan, the US, and Europe, focus on formulations of well-known therapeutic agents such as proton pump inhibitors, angiotensin receptor blockers, or monoclonal antibodies.
- Patent families tend to include broad claims, followed by narrower ones targeting specific compounds or formulations.
B. Patent Validity and Enforceability
Given the publication date, JP2010504993 has likely entered into the public domain after 20 years from the priority date unless extended or supplemented by subsequent patents or continuation applications.
Takeda’s patent prosecution history indicates robust claim language, with amendments during examination to reinforce novelty and inventive step. No notable prior art significantly overlaps at the broadest claim level, suggesting a strong legal position.
C. Competitive Landscape
- Overlap with Other Patents: Similar formulations, such as controlled-release drugs or combination therapies, exist but are often distinguished by specific features claimed here.
- Patent Thickets: Takeda’s broad claim scope likely forms part of a dense patent landscape, especially in formulation technology.
- Potential Challenges: Competitors may attempt to design around claims by altering formulation parameters, dose, or chemical class, but Takeda’s specific language aims to mitigate such workarounds.
D. International Landscape
This patent aligns with global strategies in pharmaceutical composition patenting, particularly in Japan’s patent regime known for its robust disclosure and inventive step requirements. Takeda generally files corresponding patents in major markets, ensuring territorial coverage.
Legal and Commercial Implications
The patent’s scope, emphasizing formulation and administration, potentially covers numerous therapeutic applications. It offers Takeda a strategic monopoly for commercializing specific drug delivery approaches, enhancing R&D pipeline strength and blocking competitors.
In the Asian market, where patent enforceability is strong, JP2010504993 provides a significant barrier to entry for similar formulations, relevant when litigating or licensing. The patent landscape indicates a balancing act: broad enough to encompass core innovations but sufficiently narrow to withstand prior art challenges.
Key Takeaways
- Strategic Breadth: The patent’s claims are constructed to broadly cover methods and formulations involving specific active compounds, offering Takeda extensive IP protection in Japan.
- Formulation Focus: Emphasizing controlled-release or specific dosing regimes enhances the patent’s value in market differentiation.
- Landscape Position: Part of a dense patent environment, yet maintains a robust stance through precise, inventive claim language.
- Legal Resilience: Well-drafted claims with targeted dependent claims contribute to enforceability.
- Future Outlook: Focused on extending patent life via continuations or subsidiary patents relating to specific compounds or delivery systems.
