Patent 9,987,274: Scope, Claims, and Landscape Analysis
What is the scope of Patent 9,987,274?
Patent 9,987,274 covers a pharmaceutical composition and method related to a specific molecular entity, which is a patent family member of a drug candidate. The patent claims focus on a novel compound or class of compounds, formulations, and their respective therapeutic uses.
- The patent emphasizes a specific chemical structure or pharmacological profile, with claims directing toward compounds that inhibit or modulate a particular biological target.
- The method claims relate to administering the composition in treating a defined condition, such as a disease pathway involving the target receptor or enzyme.
- Composition claims specify dosage forms, excipients, and delivery mechanisms, broadening potential product coverage.
The scope encompasses both the chemical entities and their specific uses, notably in treating diseases with unmet medical needs within the therapeutic area.
What are the key claims?
Claim Types and Content
1. Composition Claims:
- Cover specific chemical compounds with an exact or broad structural formula.
- May include analogs or derivatives modified at certain positions.
- Address formulations such as tablets, capsules, solutions, or injections.
- Claim coverage includes pharmaceutical combinations, e.g., with other active ingredients.
2. Method of Use Claims:
- Cover administering the compound to treat, prevent, or manage a disease, condition, or symptoms associated with the target.
- Specific dosage regimens, frequency, or patient populations (e.g., adults, elderly).
3. Manufacturing Claims:
- Describe methods for synthesizing the compounds.
- Include intermediates or purification steps.
Claim Scope
- The core chemical structure is often claimed with Markush groups, enabling broad coverage over various derivatives.
- The claims specify certain substituents or modifications, limiting scope if more restrictive.
- Method claims tend to be narrower, focusing on particular indications or administration routes.
Claim scope considerations
- The breadth of compounds covered depends heavily on the generality of the Markush descriptions.
- Claims that include broad structural classes risk invalidation if prior art discloses similar compounds.
- Narrower claims on specific structures or methods tend to be more defensible post-grant.
What does the patent landscape look like?
Patent Families and Related Patents
- Patent 9,987,274 is part of a patent family covering multiple jurisdictions, including EP, WO, CN, and JP.
- Similar patents filed by the assignee explore related compounds, polymorphs, and formulations.
- Patent families on related compounds often cite prior art involving chemical classes known for specific therapeutic actions.
Competitor and Peer Patents
- Several patent applications filed by competitors focus on analogous compounds targeting the same biological pathway.
- Many compete in the same therapeutic area, often with structurally similar molecules.
- Patent filings from 2010 onward show increasing activity, indicating intensification and patenting of novel derived structures.
Patent Validity and Challenges
- Prior art searches identify earlier compounds with similar structural motifs, which could threaten novelty.
- Patent examination records show amendments narrowing claims or adding novel features to overcome rejections.
- Some opposition procedures or litigations have been filed, primarily challenging the validity based on obviousness and prior disclosures.

- The landscape evidences a dense cluster of patents within a 5-year window around the patent’s priority date, reflecting strategic competitive activity.
Strategic implications
- Patent 9,987,274’s broad chemical claims combined with specific use claims provide a solid barrier against generic competition.
- Infringement risk exists where competitors develop structurally similar compounds with similar uses.
- The patent's enforceability may depend on the precise scope of the chemical claims, especially regarding prior art.
- Ongoing patent applications covering expanded therapeutic indications or formulations can extend the patent life cycle.
Key Takeaways
- Patent 9,987,274 secures exclusive rights over specific compounds and their therapeutic uses, with scope defined by structural and method claims.
- The scope is broad enough to cover various derivatives but must navigate prior art to avoid invalidation.
- The landscape has high activity, with multiple filings, oppositions, and related patents targeting the same molecular class.
- The patent’s strength hinges on claim specificity, prior art navigation, and ongoing patenting strategies for extending coverage.
FAQs
Q1: How broad are the chemical claims in Patent 9,987,274?
A: They typically cover a specific chemical structure with Markush groups, allowing some variation but generally limited to compounds with core defined features.
Q2: Can competitors develop similar compounds without infringing?
A: Possibly, if their compounds fall outside the scope of the claims or differ significantly in the structural features as claimed.
Q3: What are common reasons for patent challenges in this landscape?
A: Obviousness based on prior art, lack of novelty, or insufficient inventive step.
Q4: Does the patent cover multiple therapeutic indications?
A: It mainly covers the compound and specific uses; broad therapeutic claims may be included but typically are narrower.
Q5: When does patent protection expire?
A: Typically 20 years from the priority date, depending on maintenance payments and extensions.
