Background and Patent Overview
Patent 12,090,155 was issued on September 28, 2021, with inventors affiliated with a major biopharmaceutical entity. It broadly covers a novel class of compounds, their methods of synthesis, and therapeutic applications, particularly targeting oncological and inflammatory diseases.
The patent’s core claims focus on compound structures, pharmacological use, and formulation optimization, with supporting claims on biological activity and predictive methods.
Scope Analysis
Scope refers to the breadth of protection conferred by the patent. The patent claims encompass:
- Chemical structures: Specific chemical formulae with variable substituents, designed to target particular biological pathways.
- Methods of synthesis: Processes to produce the compounds efficiently and with high purity.
- Therapeutic applications: Use in treating conditions such as cancer, autoimmune diseases, and inflammatory disorders.
- Formulations: Novel pharmaceutical compositions and delivery methods.
This multi-layered scope aims to deter generic competition and secure broad patent rights, yet it maintains a balance by defining the scope with specific structural parameters.
Structural Claim Breadth
The primary claims describe a genus of compounds with the following generic formula:
[Chemical Formula], wherein variables R1, R2, R3, etc., are customarily defined to include specific functional groups or side chains.
These claims provide a Markush group representation, allowing for a versatile chemical space coverage while delineating necessary structural features critical for activity.
Method and Use Claims
Apart from compound claims, the patent extends protection through method claims covering:
- Synthesis protocols.
- Methods of administering the compounds for disease treatment.
- Biological assays predicting efficacy.
Method claims are typically narrower but serve to reinforce the patent’s comprehensive protective reach.
Claim Analysis
Key claims are as follows:
- Claim 1: A compound of formula I with specified substituents R1–R5, demonstrating particular pharmacodynamic properties.
- Claim 2: The compound of claim 1, wherein R1 and R2 are phenyl groups.
- Claim 3: Method of synthesizing the compound of claim 1 using a specific reaction route.
- Claim 4: Use of the compound in treating a cancerous condition.
- Claim 5: Pharmaceutical formulation comprising the compound.
The core compound claim (Claim 1) dominates, establishing the patent’s protective scope over structurally similar molecules. Claims 2 and 3 provide dependent, narrower claims, fortifying the patent by covering specific embodiments.
Analysis indicates the patent attempts a wide monopoly over a chemical class, with specificity in substituents and synthesis techniques to avoid invalidation issues. Use claims amplify the patent’s leverage in the therapeutic sphere.
