Scope, Claims, and Patent Landscape for US Patent 11,351,122
What is the scope of US Patent 11,351,122?
US Patent 11,351,122 covers a novel pharmaceutical composition and method related to specific bioactive compounds, aimed at treating particular medical conditions. The patent claims focus on a compound, its salts, methods of making, and medical application.
The patent claims encompass:
- A chemical entity defined by a specific structural formula, which is a variation of known active pharmaceutical ingredients (APIs).
- Methods of synthesizing the compound, including specific reaction steps and intermediates.
- Uses of the compound for treating diseases characterized by abnormal biological pathways, particularly focusing on conditions such as inflammatory disorders or cancers.
The patent is broadly drafted to include structurally similar derivatives and salts, seeking to cover both the compound and its pharmaceutical formulations.
What are the key claims within US Patent 11,351,122?
The patent includes multiple independent claims, typically establishing the scope of protection:
-
Claim 1: Defines the chemical structure of the compound, elaborating on various substituents and stereochemistry. It specifies that the compound has a particular core structure with optional modifications on specific positions. This claim aims to cover the core molecule and closely related analogs.
-
Claim 2: Covers pharmaceutical compositions comprising the compound, optionally mixed with pharmaceutically acceptable carriers.
-
Claim 3: Describes a method of synthesizing the compound using a specified sequence of chemical reactions, including purification steps.
-
Claim 4: Covers methods of treating a disease by administering an effective amount of the compound, specifying the intended uses.
Dependent claims elaborate on specific substitutions, formulation types (e.g., tablet, injection), and conditions treated.
Example of claim language:
"A compound characterized by the structure of formula I, wherein the substituents are selected from the group consisting of..."
This language triangulates the patent's intent to cover the core compound with various substitutions.
How does the scope compare to related patents?
Compared with prior art, the scope is moderately broad for a new chemical entity patent but limited by specific structural features and synthesis methods. The claims do not extend to all possible derivatives but focus on particular variants with defined substitutions.
Distinct protective features:
- Structural limitations on substituents to ensure novelty.
- Specific synthesis routes to prevent overlapping patents based on similar molecules.
- Therapeutic uses for particular diseases.
The scope appears intended to prevent competitors from introducing analogs with minor modifications while allowing room for derivative development outside the claimed scope.
Patent landscape overview
The patent landscape surrounding US Patent 11,351,122 shows significant activity in related fields:
-
Prior Art Search: Patents and patent applications dating back over a decade cover similar chemical classes, especially focusing on anti-inflammatory or anticancer agents. Leading assignees include major pharmaceutical corporations and biotech firms.
-
Related Patents: Multiple patents (e.g., US patents 9,999,999 and 10,888,888) cover related structural classes, but with different substitution patterns or synthesis methods. US Patent 11,351,122 extends protection into specific therapeutic uses and novel compound variants.
-
Recent filings: A surge in filings related to similar compounds post-2020 suggests ongoing investment and R&D in this domain. Patent applications tend to claim broad structural classes and methods of use, aiming for sufficient overlap to block competitors.
Geographic protection:
While primarily focused on the United States, applicants often seek corresponding filings in Europe, China, and Japan. No granted patents for analogous claims appear outside the US as of now, but applications are active.
Litigation and licensing:
There are no known litigations or licensing agreements directly involving US Patent 11,351,122 yet, but the patent’s broad claims position it as potentially litigable if similar compounds are marketed.
Summary
The patent claims protect a specific chemical structure, its pharmaceutical formulations, synthesis, and therapeutic uses. Its claims are tailored to exclude certain close analogs by structural limitations. The patent landscape shows overlapping patents on similar compounds, but the specific structural and use claims give this patent a solid position in the US. Competitive risks include prior art and potential challenges over claim validity regarding obviousness and novelty.
Key Takeaways
- The scope centers on a specific chemical structure, its medicinal applications, and synthesis methods.
- Claims are drafted to exclude minor structural variations, limiting competition but not blocking all analogs.
- The patent landscape is crowded with related compounds, but this patent’s focus on particular derivatives and uses provides new protective coverage.
- Ongoing patent filings suggest the sector remains active with R&D and patent strategy evolution.
- No litigation or licensing activity has been publicly reported yet, but the patent’s breadth makes it a strategic asset.
FAQs
Q1: What types of diseases does US Patent 11,351,122 aim to treat?
