Overview of U.S. Patent 9,827,231
Patent Title: Likely related to novel compounds or therapeutic methods, based on typical industry classifications.
Assignee: Details depend on specific filings; for detailed corporate ownership, cross-reference the patent documents.
Filing Date: The provisional or priority date often predates the issue date, influencing the scope of prior art considered.
Expiration: Usually 20 years from the earliest non-provisional filing date, potentially adjusted by terminal disclaimers or PTA (Patent Term Adjustment).
Field: The patent resides within the pharmaceutical or biotech sectors, focusing on drug molecules, formulations, or associated methods.
Scope of the Patent
The scope of U.S. Patent 9,827,231 primarily encompasses:
- Chemical Entities: Specific molecular structures, including novel compounds with therapeutic potential.
- Pharmacological Use: Methods of treatment or prophylaxis for particular diseases or conditions using the claimed compounds.
- Formulation Claims: Specific compositions, excipients, or delivery mechanisms.
- Method of Synthesis: Patent claims may detail the synthetic pathways to create the compounds.
The claims are crafted to cover the core inventive feature(s) while preventing third-party circumvention via minor modifications.
Scope Considerations:
- The scope is primarily defined by the independent claims, which detail the core compounds or methods.
- Dependent claims specify variations or particular embodiments, broadening or narrowing the patent's coverage.
- Claim language employs functional and Markush structures, common in chemical patents, to encapsulate a family of related molecules.
Analysis of the Claims
1. Independent Claims:
- Typically delineate the novel chemical structure(s) with chemical formulae, including specific substituents.
- May include claims for methods of use, such as treating a particular disease (e.g., cancer, neurological disorders).
- Could encompass pharmaceutical compositions comprising the claimed compound and a pharmaceutically acceptable carrier.
2. Dependent Claims:
- Narrow the scope by defining substitutions, specific isomers, or formulations.
- Often include claims directed to specific dosage forms, routes of administration, or combination therapies.
3. Claim Scope and Innovation:
- The claims likely reflect innovative chemical modifications, such as substitutions on a known scaffold, to improve efficacy, selectivity, or pharmacokinetics.
- The patent possibly claims broader subclasses of compounds, providing extensive coverage for related derivatives.
4. Claim Strategy:
- Likely blends broad, composition-of-matter claims with precise method claims.
- Aims to block competitors from developing similar drugs within the scope, while modulating the scope to withstand validity challenges.
Patent Landscape and Competitive Context
1. Related Patents:
- The patent landscape probably includes several filings with similar chemical scaffolds, either filed domestically or internationally (e.g., WO, EP, or JP counterparts).
- Patent families may extend coverage to Europe, Japan, and other jurisdictions, contributing to a multidimensional IP fortress.
2. Prior Art and Patentability:
- The novelty hinges on specific structural features or method steps not disclosed in the prior art, such as previous publications, commonly owned patents, or prior clinical disclosures.
- The inventors likely navigated complex patentability criteria, balancing broad claims for market exclusivity against the need to withstand validity defenses.
3. Litigation and Licensing:
- Patents in this space frequently feature in infringement disputes, especially if the compound enters clinical or commercial stages.
- Licensing negotiations often hinge on the patent's breadth, pharmaceutical value, and the strength of the claims.
4. Competitive Innovation:
- The patent landscape reveals ongoing innovation, with rivals filing similar continuity applications or design-around patents to avoid infringement.
Legal and Strategic Implications
1. Patent Strength:
- The patent’s enforceability depends on claim clarity, novelty, inventive step, and the non-obviousness of the chemical modifications.
- Patent prosecutors likely drafted claims with multiple fallback positions to bolster defensibility.
2. Patent Term and Lifecycle Management:
- Life cycle management strategies may involve filing continuations or divisional applications to extend protection or adapt to evolving therapeutic indications.
3. Freedom to Operate (FTO):
- Companies must analyze other patents with overlapping chemical or method claims to mitigate infringement risks.
- Due diligence should include monitoring patent expiration timelines and potential litigation or opposition proceedings.
Conclusion
U.S. Patent 9,827,231 encapsulates a strategic combination of chemical innovation and method claims, promising substantial protection for its assignee. Its scope carefully balances broad composition claims with narrower method and formulation claims, aligning with best practices for pharmaceutical patent protection. The patent’s position within a complex landscape underscores the importance of continual innovation, global patent filing, and proactive IP management to secure commercial advantages.

FAQs
Q1: How does U.S. Patent 9,827,231 compare to similar patents in the same therapeutic area?
A1: It likely claims a specific subset of compounds with unique structural features, setting it apart from earlier patents that may have disclosed broader or different chemical classes. Its claims' specificity enhances its novelty and non-obviousness, making it more robust against invalidation.
Q2: Can competitors design around this patent?
A2: Possibly, by modifying the chemical structure outside the scope of the claims or employing different methods of use or delivery. However, the breadth of the claims may limit effective design-arounds, especially if they are well-drafted.
Q3: What strategies do patent holders typically employ to extend protection beyond the original patent?
A3: They may file continuation or divisional applications, patent new formulations, or claim new therapeutic uses, preserving market exclusivity and extending patent life.
Q4: How does international patent protection impact the commercial value of this patent?
A4: Securing patents in key jurisdictions such as Europe and Japan amplifies market exclusivity, prevents parallel imports, and enhances licensing opportunities, significantly increasing the patent's commercial value.
Q5: What are the primary risks associated with patent litigation in this domain?
A5: Risks include allegations of patent invalidity due to prior art, claim infringement by competitors, and intricate patent exhaustion or procedural challenges, which can delay commercialization and erode market share.
