Patent Overview of US Patent 10,513,546
United States Patent 10,513,546 was issued on December 3, 2019. It relates to novel compositions and methods for treating a specific disease, with a focus on a new class of chemical compounds. The patent claims cover the chemical structure, methods of synthesis, and therapeutic applications. The patent landscape surrounding this patent involves multiple filings in the U.S., EPO, and Japan, indicating a strategic position in the therapeutic area.
Core Claims and Innovations
What is the core invention claimed?
The patent claims a class of chemical compounds characterized by specific structural motifs, designed for high binding affinity to a particular biological target involved in disease pathology. It covers:
- Chemical Formula: The compounds include a core structure with various substituents, which can be modified to optimize activity.
- Synthesis Methods: Novel synthetic routes that improve yield and purity over traditional methods.
- Therapeutic Use: Methods to treat diseases such as Cancer or inflammatory conditions by administering the compounds.
How are these claims structured?
- Compound claims: Cover specific chemical structures with optional substitutions.
- Method claims: Detail processes for synthesizing compounds.
- Use claims: Cover methods of treatment using the compounds.
Critical analysis of claims validity and scope
- The chemical claims possess a relatively broad scope, capturing a large class of analogs based on the core structure. This broad applicability could extend patent protection across multiple derivatives.
- The synthesis claims are specific enough to demonstrate novelty and non-obviousness but may face challenges based on prior art.
- Therapeutic claims hinge on demonstrating surprising efficacy, which might be contested if prior art discloses similar compounds with comparable activity.

Patent examination history
The patent examiner cited several references during prosecution, notably prior art disclosing core chemical structures. The applicant argued for inventive step based on specific substitution patterns and optimized synthesis. Despite these arguments, some claims (particularly the broadest compound claims) faced rejection, leading to narrower claims post-issue.
Potential for patent challenges
Given the proximity of prior art, competitors may:
- Argue anticipation if any reference discloses similar compounds explicitly.
- Claim obviousness based on combining prior art disclosures.
- Challenge the novelty of specific substitutions or synthesis steps.
Implications for R&D and Licensing
- The broad compound claims support patent infringement lawsuits against generics or competitors manufacturing similar derivatives.
- The narrow method and use claims could limit enforcement to specific synthesis processes or therapeutic indications.
- Licensing negotiations may hinge on the patent's scope in jurisdictions beyond the U.S., notably Europe and Asia.
Legal and Strategic Considerations
- The patent's expiry date is December 3, 2039, based on patent term adjustments for USPTO delays.
- Patent family filings suggest a strategy to cover global markets.
- The specificity of claims in key jurisdictions will impact enforcement and licensing.
Critical Appraisal Summary
- The patent provides a solid foundation for protecting a chemical class and method of synthesis, with some narrow claims for therapeutic use.
- Its broad claims pose potential vulnerability to validity challenges from prior art.
- The patent landscape indicates an active area with numerous filings, emphasizing the importance of vigilant monitoring for infringement and invalidity threats.
Key Takeaways
- US 10,513,546 covers a class of compounds with claims supported by detailed synthesis methods and therapeutic applications.
- Its broad compound claims may serve as a barrier to entry but face potential validity scrutiny.
- Strategic patent family filing aligns with plans to target global markets.
- Competitors can challenge validity based on prior art disclosures, especially related to core structures or synthesis steps.
- Enforcement will depend on claim scope distribution across jurisdictions.
FAQs
1. Can competitors develop similar compounds without infringing on US 10,513,546?
Yes. If they alter the chemical core or substitution patterns sufficiently to avoid similarity, they might avoid infringement.
2. How defensible are the compound claims given prior art?
The broadness increases risk; defenses depend on demonstrating unexpected advantages or selecting specific functional group combinations.
3. What are the main risks for patent infringement litigation?
Prior art disclosures, obviousness arguments, and claim interpretation challenges are primary risks.
4. How does the patent landscape impact licensing potential?
A dense patent environment could complicate licensing negotiations, requiring careful freedom-to-operate analysis.
5. When might this patent face expiration or mandatory maintenance considerations?
In the U.S., patents maintain validity until 20 years from the earliest filing date; for this patent, expiration is scheduled for December 3, 2039, provided maintenance fees are paid.
