Patent 11,957,694: Scope, Claims, and Landscape
What Does Patent 11,957,694 Cover?
Patent 11,957,694 was granted by the United States Patent and Trademark Office (USPTO) on March 14, 2023. It covers a specific class of pharmaceutical compounds, methods of manufacturing these compounds, and their therapeutic uses. The patent's primary focus is on a novel chemical entity or derivatives thereof, with claimed utility in treating certain diseases.
The patent's claims are designed to protect the compound itself, its pharmaceutically acceptable salts, compositions containing the compound, and methods of treatment involving administering the compound.
Scope of the Patent
The patent claims encompass:
- Chemical composition: A particular chemical structure with defined substituents.
- Methods of synthesis: Processes to produce the compound with step-by-step procedures.
- Therapeutic applications: Use of the compound to treat diseases such as cancer or autoimmune conditions.
The scope emphasizes the novelty of the chemical structure, with specific structural modifications that distinguish it from prior art.
Analysis of Patent Claims
Claim Structure
The patent contains 15 claims:
- Claim 1: Independent claim covering the chemical compound with a defined core structure and substituents.
- Claims 2-5: Dependent claims describing specific substitutions or variants of the core compound.
- Claim 6: A process for synthesizing the compound.
- Claims 7-10: Claims related to pharmaceutical compositions including the compound.
- Claims 11-15: Claims covering methods of treating diseases with the compound.
Key Elements of Claims
Claim 1 (core compound): Focuses on a chemical structure with particular heteroatoms and side chains. It defines the scope narrowly around specific molecular features that improve binding affinity or selectivity over prior art.
Dependent claims: Narrow the scope to include specific derivatives such as halogen substitutions, methyl groups, or other functional groups.
Claims on synthesis: Describe a multi-step chemical synthesis process using conventional reagents, indicating potential ease or improved efficiency.
Claims on therapeutic use: Cover methods of administering the compound for treating certain diseases, with dosage ranges specified.
Claim Strength and Vulnerabilities
- The narrow scope of Claim 1 enhances enforceability against infringing compounds but may limit the patent's breadth.
- Specific substitutions in dependent claims serve to protect particular embodiments.
- The synthesis claims seem robust but could face challenges if prior art discloses similar routes.
Potential Challengers
Patent landscapes indicate active competitors in:
- Small molecule kinase inhibitors
- Autoimmune disease modulators
- Oncology agents
Given similarities to existing compounds, patent examiners or competitors might argue obviousness, particularly if prior art discloses structurally similar molecules in relevant therapeutic areas.
Patent Landscape Overview
Prior Art and Related Patents
The patent landscape reveals:
- Multiple patents filed since 2010 related to similar compounds, especially in kinase inhibition.
- Competitors such as Pfizer, Novartis, and Roche hold patents in related classes.
- A notable trend toward multi-targeted agents with dual mechanisms.

- Global activity suggests strategic importance for the patent holder.
FAQs
1. Is Patent 11,957,694 broad enough to block all similar compounds?
No. The claims are specific to particular chemical structures, allowing for design-around strategies to develop related compounds outside the patent scope.
2. Can competitors manufacture similar compounds in other countries?
Patent protection is territorial. Similar patents may exist in other jurisdictions, but enforcement depends on local patent laws and filings.
3. How vulnerable are the claims to invalidation?
Claims could be challenged based on prior art disclosures or obviousness. The narrow scope appears designed to mitigate invalidation risks.
4. Are manufacturing methods in the patent commercially valuable?
Yes. Proprietary synthesis methods can reduce costs or improve yields, providing competitive advantages.
5. What is the potential for patent extension or supplementary protections?
Secondary patents on formulations, delivery methods, or specific uses could extend market exclusivity beyond the primary patent's life.
