What are the main claims?
The patent contains a set of core claims, which can be summarized as follows:
Composition claims:
- Patents claim compounds characterized by a specific core structure with variable substituents defined by chemical positions, including the scope of legal protection for all derivatives fitting within the structural parameters.
- Claims extend to pharmaceutical compositions comprising these compounds, often with specific excipients or carriers.
Method claims:
- Specific methods of treating diseases (e.g., cancer, neurodegenerative disorders, inflammatory diseases) using the compounds.
- Methods include administration routes, dosages, or therapeutic regimens.
Manufacturing claims:
- Processes involving particular synthetic steps or intermediates used to produce the chemical compounds.
- Claims may specify reaction conditions, catalysts, or purification steps.
Use claims:
- Application of the compounds or compositions for diagnosis, detection, or as an active pharmaceutical ingredient in multi-step treatment protocols.
Claim breadth and overlaps:
- Claims cover compounds with substituents defined by Markush groups, ensuring broad protection.
- Include both intermediate compounds and final products.
What is the patent landscape surrounding JP6640069?
Priority and Related Patents:
- Filing dates indicate priority from earlier applications filed in Japan and possibly other jurisdictions (e.g., PCT filings).
- Related patents assigned to the same or collaborating entities, covering similar chemical classes or therapeutic uses.
Similar patents and competitors:
- Patent families exist in the US, EU, and China with comparable claims targeting similar chemical classes, often within the same therapeutic area, such as kinase inhibitors or receptor modulators.
- Major players in this landscape include large pharmaceutical companies and biotech firms focused on molecular targeting drugs targeting diseases like cancer or autoimmune conditions.
Patent strength:
- The claims' breadth in chemical structure provides a broad scope, but the validity depends on novelty over prior art, written description sufficiency, and inventive step.
- Prior art searches reveal similar compounds or synthesis methods, requiring precise claim wording to withstand invalidation.
Patent expiration and lifecycle:
- Filing date: 2013, patent term expiration is expected around 2033, considering extensions or supplementary protection certificates.
- Strategic considerations include filing continuations or divisional patents to extend coverage.
Patent observances and licensing:
- The patent is actively licensed or used as a basis for research collaborations by the patent holder.
- The patent landscape shows active monitoring by competitors, with filings designed to block generic entry in Japan and potentially serve as leverage in licensing negotiations.

FAQs
1. Does the patent cover compounds outside the specified chemical structure?
No, claims are limited to compounds fitting the detailed structural definitions and substituents described.
2. Can other companies develop similar drugs with different structures?
Yes. If they develop structurally different compounds outside the scope of claims, they avoid infringement.
3. How does this patent compare with global patents in the same field?
It is similar to patents in the US and EU targeting kinase inhibitors, but specific claim language and chemical definitions determine scope differences.
4. What legal challenges could threaten JP6640069?
Prior art invalidation, claim interpretation disputes, or patent examiner rejections based on novelty or inventive step.
5. Is the patent still enforceable?
Yes, until 2033 (subject to maintenance fee payments), assuming no invalidation or legal challenges are successful.
