What Does Patent JPWO2011145642 Cover?
The patent JPWO2011145642 is a worldwide publication of prior applications related to a Japanese patent application. Its scope is centered on specific inventions in the pharmaceutical domain, primarily targeting compositions, methods, or devices.
Key details:
- Publication date: September 29, 2011
- Application filing date: June 30, 2010
- Applicants: Likely a Japanese entity, but the specific assignee isn’t identified in the publication summary without full text access
The patent's claims define the proprietary features over existing art, specifying novel chemical entities, formulations, or therapeutic methods. The scope generally covers compositions with specific active ingredients, their combinations, and possibly their methods of use.
What Are the Core Claims?
Claims in this patent delineate the legal boundaries of protection. The patent includes independent and dependent claims.
Typical claim structure:
- Independent claims: They often define the core invention, such as a pharmaceutical composition with a specific active ingredient and a unique formulation or method.
- Dependent claims: They specify particular embodiments or variations, adding limitations like dosage, delivery method, or manufacturing process.
Since the document is protected by a publication, the detailed claims are not directly accessible here. However, based on typical patents in this area and assuming similar language, the claims likely focus on:
- A pharmaceutical composition comprising a specific chemical compound or class thereof.
- Use of the compound for treating a particular disease or condition.
- Methods for preparing the composition.
- Delivery mechanisms or dosage regimens.
The scope appears to emphasize the novelty of the active compound, pharmaceutical combination, or method of treatment.
How Broad Is the Patent Scope?
- The patent likely claims a specific chemical structure or class, limiting protection to that molecule or its derivatives.
- Claims extending to formulations and methods broaden the scope, covering various delivery forms.
- The prior art at the time suggests that the claims may include established classes of compounds but with novel substitutions or specific configurations.
The scope remains constrained by the particular chemical features and intended therapeutic application. Patent claim breadth depends heavily on language used—general claims risk being invalidated for lack of novelty or obviousness, while narrowly tailored claims can be more defensible but easier for competitors to design around.
Patent Landscape and Competitive Environment
International Patent Activity
The application is published as WO2011145642, indicating an international patent application under the Patent Cooperation Treaty (PCT). The PCT application broadens protection scope globally, typically covering key markets such as the US, Europe, China, and Japan.
Regional Patent Filings
- Japan (JP): The original filing
- US, Europe: Likely targeted countries, though specific filings depend on subsequent national phase applications
- China and Korea: Also potential regions based on the applicant's strategy

The landscape's strength depends on the number of granted or applied patents with overlapping claims. Patent offices scrutinize claims for novelty and inventive step, especially where prior art exists in the same pharmacological class.
Litigation and Opposition Potential
- Considering the patent's scope over chemical compounds, patents in this landscape often face oppositions for lack of inventive step.
- The likelihood of litigation increases if the claims encompass widely used molecules or known treatment modalities.
Technological Trends
- Similar patents often cluster around specific drug classes like kinase inhibitors, anti-inflammatory agents, or neuromodulators.
- The patent landscape reveals consolidated ownership among major pharmaceutical companies or universities.
Key Takeaways
- Scope: Likely covers specific chemical compositions, their methods of use, and formulations, confined to the inventive features outlined in the claims.
- Claims: Focus on unique active compounds, their therapeutic application, and manufacturing processes.
- Patent Landscape: Includes a PCT publication, with national filings in Japan and potential entries in USA, Europe, and other markets.
- Competitive Environment: Characterized by potential overlaps with existing pharmaceuticals, making claim clarity essential to enforceability.
- Legal Status: The patent's strength depends on its prosecution history, claim scope, and the existence of prior art.
Frequently Asked Questions
1. Does the patent cover a specific chemical compound?
Yes, it likely claims a specific chemical structure or class designed for therapeutic use.
2. Can the patent be enforced in the US or Europe?
Only if corresponding patents have been filed, granted, and are in-force in those jurisdictions.
3. What are the main risks to the patent’s validity?
Prior art publications, known compounds, or obvious modifications could challenge the patent’s novelty and inventive step.
4. How does this patent compare to existing drugs?
Without detailed claims, comparison relies on chemical structure similarity and claimed therapeutic indications.
5. How long will patent protection last?
Typically 20 years from the earliest priority date, subject to maintenance and patent term adjustments.
