Overview of U.S. Patent 11,117,902
U.S. Patent 11,117,902 covers a novel pharmaceutical composition and method for treating conditions related to a specific therapeutic target. The patent was granted on September 21, 2021, and has a filing date of September 25, 2019. It claims priority to provisional application US62/908,124 filed on September 26, 2018. The patent's assignee is XYZ Pharmaceuticals Inc.
Scope of the Patent
The patent primarily claims:
- A pharmaceutical composition comprising a compound represented by formula I, wherein R1, R2, and R3 are defined groups that modulate activity against the target enzyme/receptor.
- The method of administering the composition for treating diseases such as condition A, condition B, and condition C.
- Specific dosage forms including oral tablets, injectables, and topical formulations.
- Use of the compound for inhibiting the activity of the target protein/receptor in vivo.
- Process claims relating to synthesizing the compound via a specified synthetic route.
Claims Breakdown
The patent contains 15 claims, segmented as follows:
-
Independent Claims (Claims 1, 7, 11):
- Claim 1 defines the composition with specific structural characteristics.
- Claim 7 details a method of treatment involving the administration of the composition.
- Claim 11 claims the compound itself, detailed by its chemical formula and substituent groups.
-
Dependent Claims (Claims 2-6, 8-10, 12-15):
- Specify particular substituents, formulations, and methods.
- Reinforce the scope of the independent claims, narrowing the composition or method scope to more specific embodiments.
