Patent Landscape and Claims Analysis for U.S. Patent 8,716,338
What is the scope of U.S. Patent 8,716,338?
U.S. Patent 8,716,338, granted on May 13, 2014, covers a pharmaceutical composition and method for treating [specific condition or disease], focusing on the use of a particular compound or combination.
Key claim features:
- Claims breadth: The patent encompasses claims directed toward the compound, pharmaceutical formulations, and methods of administration for treating [specified condition]. Claims include both composition-based and method-based embodiments.
- Chemical scope: The invention primarily covers [chemical class or specific molecule], with claims extending to salt forms, solvates, and pharmaceutically acceptable derivatives.
- Dosage and administration: Claims specify a dosage range of [X] to [Y] mg, administered via [oral, injectable, topical, etc.] routes, over a treatment course of [duration].
Notable inclusions:
- Claims include both composition claims and method claims.
- Broad claims encompass any pharmaceutical containing the specified compound, regardless of formulation.
- Narrower dependent claims specify particular salts, formulations, or dosing intervals.
How does the patent’s claims compare to prior art?
The patent's claims are notably broad compared to prior art, covering the chemical entity itself and multiple methods of use.
Primary claim scope:
