Analyzing the Scope and Claims of a U.S. Patent: A Detailed Guide Using Patent 11,690,854 as an Example
Understanding the Basics of U.S. Patents
Before diving into the specifics of a particular patent, it's essential to understand the fundamental components of a U.S. patent. Patents are granted to inventors for new and useful processes, machines, manufactures, or compositions of matter, or any new and useful improvement thereof, as defined by Title 35 of the U.S. Code[2].
Types of Patent Applications
There are three main types of patent applications: utility, design, and plant patents. The most common type is the utility patent, which covers functional inventions[2].
The Role of Claims in a Patent Application
Claims are the heart of a patent application, defining the scope of the patent's protection. They must be clear, concise, and supported by the specification and drawings included in the application[2].
Conducting a Patent Search
To analyze the scope and claims of a patent, one must first locate the patent document. Here are some resources for conducting a patent search:
Using the USPTO Patent Public Search Tool
The USPTO's Patent Public Search tool is a powerful resource for finding patent documents. It replaces older tools like PubEast and PubWest and offers enhanced access to prior art[1].
Global Dossier and Common Citation Document
The Global Dossier service allows users to view the file histories of related applications from participating IP Offices, including the IP5 Offices. The Common Citation Document (CCD) consolidates citation data from these offices, providing a single point of access for prior art citations[1].

Locating the Patent Document
To analyze the scope and claims of U.S. Patent 11,690,854, start by searching for the patent using the USPTO's Patent Public Search tool or other patent databases like Google Patents or Espacenet[1][4].
Understanding the Specification and Drawings
The specification and drawings are crucial components of the patent application. They provide a detailed description of the invention and how it works. Review these sections to understand the invention's core concepts and how they are implemented.
Examining the Claims
The claims section is where the scope of the patent's protection is defined. Here, you will find a series of numbered claims that outline what the inventor is seeking to protect. These claims must be novel, non-obvious, and useful to be valid[2].
Claim Types and Scope
- Independent Claims: These claims stand alone and define the broadest scope of the invention.
- Dependent Claims: These claims build upon independent claims and narrow the scope further.
- Method Claims: These claims describe a process or method.
- Apparatus Claims: These claims describe a device or system.
Claim Coverage Matrix and Scope Concepts
To better understand the coverage of the claims, a Claim Coverage Matrix can be useful. This matrix categorizes patents by claims and overarching scope concepts, helping to identify gaps or opportunities in the patent landscape[3].
Patent Landscape Analysis
Identifying Related Patents
Use tools like the Global Dossier and Common Citation Document to identify related patents and understand the broader patent family. This helps in visualizing the prior art cited by multiple offices and identifying potential overlaps or gaps in protection[1].
Tracking Patents by Claims and Scope Concepts
Categorize the patents by claims and scope concepts to filter, search, and analyze large numbers of patent claims efficiently. This approach, as used in Schwegman’s ClaimScape® software, generates interactive claim charts that can be reviewed by technical experts to determine coverage and identify future design opportunities[3].
Determining Inventorship
Correctly determining the inventors is crucial for the validity of the patent. U.S. patent law requires that only the true and only inventors be listed. The process involves conception of the idea and reduction to practice, and any errors can lead to legal issues[5].
Key Takeaways
- Claims Define Protection: The claims section of a patent application is critical as it defines the scope of the patent's protection.
- Patent Search Tools: Utilize tools like the USPTO's Patent Public Search, Global Dossier, and Common Citation Document to locate and analyze patents.
- Claim Coverage Matrix: Use a Claim Coverage Matrix to categorize patents by claims and scope concepts to identify gaps and opportunities.
- Inventorship: Ensure that only the true and only inventors are listed on the patent application to avoid legal complications.
- Patent Landscape: Analyze the broader patent landscape to understand related patents and prior art.
