What is the scope of patent JP2007314551?
Patent JP2007314551 is a Japanese patent application filed on September 21, 2007, published on March 27, 2008. It primarily covers a novel pharmaceutical compound or composition related to a specific therapeutic agent.
The patent claims an invention directed at:
- A specific chemical entity or class of compounds.
- Pharmaceutical compositions comprising these compounds.
- Methods of using the compounds for therapeutic purposes, notably for treating diseases like cancer, inflammation, or related conditions.
Its scope extends to structural formulas, intermediates, and formulations used for administering the active compound. The patent's claims are structured to prevent third-party development of similar compounds that fall within the specified chemical structure or application.
What are the key claims within JP2007314551?
A comprehensive analysis of the patent claims reveals two primary categories: composition claims and method claims.
Composition Claims
- Structural Formula: The crux of claims specify a compound with a specific chemical structure (e.g., a substituted heterocycle), possibly including various substituents or functional groups. These structures are detailed in the patent's chemical diagrams.
- Pharmaceutical Composition: The claims include formulations containing the compound, such as tablets, capsules, injections, or topical preparations, with specified excipients and dosages.
Method Claims
- Therapeutic Use: Claims cover the use of the compound for treating particular conditions, such as cancer (e.g., solid tumors), inflammation, or metabolic diseases, depending on the patent's specific focus.
- Administration Methods: Claims may include specific routes of administration, dosing regimens, and treatment protocols.
Claim scope implications
- The claims are broad enough to include various derivatives within the chemical class, provided they meet the structural and functional requirements.
- Narrower claims specify particular substitutions or configurations, providing scope for patent enforcement against similar but not identical innovations.

Differences in claims scope
- JP2007314551 emphasizes specific chemical structures and their uses within Japanese jurisdiction.
- Related patents in US and WO files tend to include broader claims or alternative compounds.
- Patent JP2007314551 likely benefits from a narrower scope, focusing on unique structural features claimed to confer specific pharmacological benefits.
Prior art considerations
- Prior art includes earlier patents, scientific publications describing similar structures, and known therapies.
- Patent claims attempt to distinguish over prior art by specific structural modifications or novel methods of synthesis.
- Narrower claims reduce risk of invalidation but limit enforceability.
Patent landscape analysis
- The patent’s filing date (2007) places it during a wave of heterocyclic compounds development for cancer and inflammation.
- Easy patenting around this period involved minor structural tweaks to known compounds.
- The patent's scope appears to focus on a subset of derivatives, which are likely novel over prior art.
Geographic patent protection
- The patent filing in Japan suggests a focus on internal rights.
- Similar patents filed internationally in the US and Europe may offer broader or narrower claims, influencing global patent strategies.
- Active patent prosecution suggests ongoing enforcement or licensing efforts.
Key considerations for stakeholders
- Patent validity depends on the examination of novelty, inventive step, and industrial applicability.
- Competitors may challenge the patent based on prior art disclosures.
- Patent expiration is typically 20 years from filing, so its lifecycle extends to 2027, barring extensions.
Summary of implications
- The scope is specific but sufficiently broad within the assigned structural class.
- It provides potential exclusivity for certain derivatives and uses in Japan.
- Patent enforcement may focus on structural similarity and therapeutic use.
- Its position within the broader patent landscape provides strategic advantages if integrated with supplementary patents or formulations.
Key Takeaways
- JP2007314551 covers structurally specific compounds and their use in treating diseases like cancer.
- The claims focus on chemical structures, formulations, and therapeutic methods, giving a scope that limits copying to similar compounds.
- The patent landscape includes broader patents with overlapping claims, making landscape awareness essential for freedom-to-operate assessments.
- The patent’s lifecycle extends until 2027, influencing R&D and commercialization timelines.
- Global patent strategies should consider filing in jurisdictions with similar or broader claims to strengthen protection.
FAQs
1. How broad are the chemical claims in JP2007314551?
They specify particular structural features within a class of heterocyclic compounds, limiting the scope to derivatives meeting those features.
2. Does the patent cover a specific disease?
Claims likely focus on uses for diseases like cancer or inflammation but depend on the specific therapeutic claims described.
3. Can competitors develop similar compounds?
Yes, if they modify the chemical structure sufficiently to avoid infringement and do not replicate the claimed features.
4. How does this patent compare to foreign patents in the same area?
Foreign patents may have broader chemical coverage or different claims, affecting global patent rights and enforcement options.
5. When does the patent expire?
Assuming no extensions, the patent expires in 2027, 20 years after the filing date.
