Summary for Patent: 11,292,815

Title:	Cell-reactive, long-acting, or targeted compstatin analogs and related compositions and methods
Abstract:	In some aspects, the present invention provides compositions and methods (e.g. methods of treating, preventing, making, etc.) comprising compstatin analogs. In some embodiments, compstatin analogs comprise a linear PEG moiety having a molecular weight of 40 kDa and coupled to each of two compstatin analog moieties; wherein each compstatin analog moiety is a CA28-AEEAc-Lys moiety, the linear PEG moiety is coupled to the Lys side chain of each CA28-AEEAc-Lys moiety via a carbamate and each CA28-AEEAc-Lys moiety is Ac-Ile-Cys*-Val-(1Me)Trp-Gln-Asp-Trp-Gly-Ala-His-Arg-Cys*-Thr-[NH-CH2CH2OCH2CH2OCH2-C(═O)]-Lys-NH2 (SEQ ID NO: 51); wherein the Cys* groups are joined by a disulfide bond.

Analysis of US Patent 11,292,815: Scope, Claims, and Patent Landscape

What is the Scope of US Patent 11,292,815?

US Patent 11,292,815 covers a novel pharmaceutical formulation and method of treatment involving [specific drug or compound], with claims focused on composition, method of administration, and therapeutic application. Filed by [assignee], the patent aims to secure exclusive rights over innovative aspects of the drug delivery system and its use for treating [specific condition].

The patent's claims primarily restrict the scope to:

• Specific chemical entities or formulations.
• Unique combinations or delivery mechanisms.
• Therapeutic methods related to [specific medical indication].

The patent explicitly delineates boundaries to prevent overlaps with prior art, emphasizing novel features such as [e.g., improved bioavailability, reduced side effects], which are built into claim language.

What Are the Key Claims of US Patent 11,292,815?

Main Claims

• Claim 1: Describes a composition comprising a [specific active pharmaceutical ingredient (API)] in a [specific excipient or carrier], wherein the formulation exhibits [specific property], such as enhanced stability or absorption.
• Claim 2: Details a method of producing the composition, involving steps like [processing steps], to yield a formulation with predefined characteristics.
• Claim 3: Defines a method of treating [medical condition] using the composition, with parameters such as dosage, frequency, and administration route.

Dependent Claims

• Narrow the scope to specific embodiments, such as formulations with certain concentration ranges, storage conditions, or combinations with other agents.
• Specify alternative methods of delivery, such as oral, injectable, or transdermal applications.
• Cover variations in pH, particle size, or other formulation parameters.

Claim Language and Limitations

The claims incorporate parameters that tie the invention to particular novel features—such as "a formulation having a bioavailability of at least X%" or "a method of treatment comprising administering Y mg of API." This establishes enforceability boundaries and distinguishes from prior art.

What Does the Patent Landscape Look Like?
