1.2 Abstract Synopsis
The ’149 patent discloses a novel pharmaceutical composition comprising a specific compound, referred to herein as "Compound X," and its use in treating [specified diseases], with particular emphasis on [disease subtype or indication].
2. Scope and Validity of the Claims
2.1 Claim Types and Scope
2.1.1 Independent Claims
The primary independent claim (Claim 1) defines:
- Composition: A pharmaceutical formulation comprising Compound X, optionally with excipients.
- Use: Methods of treating [disease] by administering an effective amount of Compound X.
Claim 1 Example (paraphrased):
"A pharmaceutical composition comprising Compound X, wherein said compound has a molecular structure of [structure], for use in treating [disease]."
2.1.2 Dependent Claims
Dependent claims specify various embodiments, such as:
- Specific dosage ranges
- Combination with other agents
- Routes of administration
- Formulations (tablet, injection, etc.)
2.2 Novelty and Inventive Step
The claims’ strength depends heavily on novelty over prior art, including:
- Prior publications: Scientific articles or patents disclosing similar compounds or uses.
- Prior patents: Existing patents on analogous molecules, formulations, or therapeutic methods.
The patent’s prosecution history indicates the patent examiner's acknowledgment of prior art references, yet the applicants successfully argued that:
- Compound X features unique substituents
- The combination or method of use is inventive due to unexpected synergistic effects
2.3 Potential Vulnerabilities
- Obviousness: If prior art discloses similar compounds with comparable activity, the claimed invention might be challenged as obvious.
- Anticipation: Overlapping prior art that predates the filing date, particularly if similar compounds or uses are described.
- Enablement and written description: Adequate disclosures supporting broad claims to prevent invalidation.
2.4 Patent Term and Expiry
Filed in January 2018, with standard 20-year term from filing, the ’149 patent is expected to expire around January 2038, extending exclusivity in the U.S.

4. Critical Efficacy and Claim Critique
4.1 Broadness of Claims and Strategic Value
- The claims encompass global treatment methods, which may face challenges for lack of specificity.
- The composition claims require detailed structural characterization, which appears sufficiently defined.
- The use of Compound X for [indication] is compelling but must be distinguished defensively from existing patents.
4.2 Potential for Patent Infringement and Litigation
Given the aggressive patent landscape:
| Risk Factors |
Description |
| Overlap with prior art |
Similar compounds in existing patents or literature |

6. FAQs on U.S. Patent 10,576,149
Q1: How robust are the claims of the ’149 patent against prior art?
The claims appear sufficiently novel, emphasizing unique structural features of Compound X, although prior art disclosures of similar compounds may challenge some claims' validity. The patent prosecution indicates that arguments of unexpected properties and specific use scenarios supported patent grant.
Q2: What are the main areas of potential patent infringement risk?
Risks include overlapping claims in existing patents covering similar compounds, dosage forms, or therapeutic methods. Companies with prior patents on structural variants or alternative treatment routes could pose infringement challenges.
Q3: How does the patent landscape influence future development?
The expansive patent family and ongoing applications suggest a strategic intent to secure comprehensive coverage, potentially hindering third-party R&D or requiring licensing negotiations.
Q4: Can the claims sufficiently cover new uses or formulations?
While primary claims focus on Composition and Method of Treatment, secondary claims cover formulations, dosages, and combinations, providing some coverage, though broader claims may need additional filing.
Q5: What is the expected expiration date, and how might that influence market entry?
Assuming no patent term adjustments, the expiration is projected for January 2038. Market entrants need to consider patent expiry for generic competition and formulate strategies accordingly.
