Detailed Analysis of the Scope and Claims of United States Patent 11,230,530
Introduction
United States Patent 11,230,530, titled "Human plasma kallikrein inhibitors," is a patent that discloses compounds and their use as inhibitors of human plasma kallikrein. This analysis will delve into the key components of the patent, including its scope, claims, and the broader patent landscape.
Patent Structure and Content
Front Page and Bibliographic Data
The front page of the patent includes essential bibliographic data identified by INID codes. These codes provide information such as the document number (US11,230,530B2), document type (Patent), application number, date of application, date of patent, IPC classification, national classification, title of the invention, and references to prior art[1].
Drawings and Specification
The patent includes a drawings section, which may contain black and white drawings or, in some cases, photographs, to illustrate the technical details of the invention. However, for chemical compounds like those in this patent, drawings might be minimal or absent. The specification is a detailed written description of the invention, including discussions of prior art, descriptions of the drawings, how the invention solves a specific technical problem, and the preferred embodiment of the invention[1].
Claims
Definition and Purpose
The claims section is crucial as it defines the scope of protection for the patent. Claims are paragraphs located at the end of the specification and are preceded by phrases such as “I claim” or “What is claimed.” These claims legally define the boundaries of the invention[1].
Types of Claims
Claims can be independent or dependent. Independent claims stand alone and define the invention without reference to other claims. Dependent claims, on the other hand, refer back to and further limit an independent claim. The format of claims is highly structured, written as a single sentence, heavily punctuated, and ending with a period[5].
Claims Analysis of US11,230,530
The claims in US11,230,530 would typically include descriptions of the chemical compounds, their structures, and their use as inhibitors of human plasma kallikrein. For example:
- Independent Claim: "A compound of formula I, wherein R1, R2, R3, and R4 are defined as in the specification."
- Dependent Claim: "The compound of claim 1, wherein R1 is a methyl group and R2 is a phenyl group."
Scope of the Patent
Patent Scope Metrics
The scope of a patent can be measured using metrics such as independent claim length and independent claim count. Narrower claims, as indicated by shorter lengths and fewer counts, are often associated with a higher probability of grant and a shorter examination process[3].
