Understanding the Scope and Claims of United States Patent 8,618,174
Introduction to U.S. Patents
To analyze the scope and claims of a U.S. patent, it is essential to understand the structure and components of a patent document. The U.S. Patent and Trademark Office (USPTO) is responsible for granting U.S. patents, and each patent document contains specific sections that provide detailed information about the invention[2].
Structure of a U.S. Patent Document
A U.S. patent document is divided into several key sections:
Front Page
The front page of a U.S. patent includes bibliographic data identified by INID codes. These codes provide information such as the document number, application number, date of application, date of patent, IPC classification, and national classification. Other important details include the title of the invention, references to prior art, and the abstract[1].
Drawings
The drawings section contains black and white illustrations that depict the technical details of the invention. These drawings are crucial for understanding the physical aspects of the invention and are required for most types of inventions, although exceptions exist for process or method inventions[1].
Specification
The specification is a written description of the invention, including discussions of related prior art, descriptions of the drawings, how the invention solves a specific technical problem, and the preferred embodiment of the invention. This section must be detailed enough for anyone with ordinary skill in the same technical field to understand and replicate the invention[1].
Claims
The claims section defines the scope of protection for the patent. These claims are the legal boundaries of the invention and are typically preceded by the phrases “I claim” or “What is claimed.” Each claim is numbered, and there must be at least one claim, though most patents have multiple claims[1].
Analyzing Patent 8,618,174
Front Page Analysis
- Document Number: The prefix "US" indicates it is a U.S. patent, and the code "B2" signifies that this patent has a previously published application.
- Application Number: This is the number assigned to the application when it was filed.
- Date of Application: The date when the application was submitted.
- Date of Patent: The date when the patent was granted.
- IPC Classification: The International Patent Classification code that categorizes the invention.
- National Classification: The U.S. classification code, which provides a more specific categorization.
- Title of the Invention: A brief title that describes the invention.
- Abstract: A non-technical summary of the invention[1].
Drawings Analysis
- The drawings for Patent 8,618,174 would illustrate the technical details of the invention. For example, if the patent is for a portable electronic device, the drawings might show the device's components, such as the housing, antenna, and low frequency shield.
Specification Analysis
- The specification would provide a detailed description of the invention, including how it differs from prior art. It would explain the technical problem the invention solves and describe the preferred embodiment.
- For instance, if the patent is for a portable electronic device, the specification might discuss how the device's design improves antenna performance in different positions.
Claims Analysis
- The claims define the legal scope of the patent. Here is an example of what a claim might look like for a portable electronic device:
1. A portable electronic device, comprising:
a first housing;
a second housing coupled to the first housing and movable relative thereto between a closed position and an open position;
an antenna positioned in the first housing;
a low frequency shield coupled to the antenna and adapted to inhibit changes to the frequency response of the antenna when the portable electronic device is moved between the open position and the closed position;
and a high frequency chassis resonator coupled to the low frequency shield and adapted to increase high frequency sensitivity of the antenna.
This claim outlines the specific components and their functions that are protected by the patent[1].
Understanding the Claims
Independent and Dependent Claims
- Independent Claims: These claims stand alone and define the invention without reference to other claims. They are typically broader in scope.
- Dependent Claims: These claims refer back to an independent claim and add additional limitations. They are narrower in scope and build upon the independent claims.
Claim Construction
- Claim construction is the process of interpreting the meaning of the claims. This is crucial for determining the scope of protection and can be a point of contention in patent litigation.
Patent Landscape
Prior Art
- The patent landscape includes prior art cited by the inventor and the patent examiner. This section helps in understanding the existing technology and how the current invention improves upon it[1].
Related Patents
- Using tools like the Patent Public Search, Global Dossier, and Common Citation Document (CCD), one can identify related patents and understand the broader patent family. These tools provide access to file histories, classification, and citation data for related applications[4].
Market Impact
- Analyzing the patent landscape helps in understanding the market position of the invention. It reveals competitors, potential collaborators, and areas where the invention might face challenges or opportunities.
Practical Applications
Licensing and Collaboration
- Understanding the scope and claims of a patent is crucial for licensing agreements and collaborations. It helps in defining what is protected and what can be shared or licensed.
Litigation
- In patent litigation, the claims are central to determining infringement. Accurate analysis of the claims can help in defending or asserting patent rights.
Key Takeaways
- Detailed Description: The specification provides a detailed description of the invention, including prior art and the preferred embodiment.
- Claims Define Scope: The claims section is critical as it defines the legal boundaries of the patent.
- Patent Landscape: Understanding related patents and prior art is essential for navigating the patent landscape.
- Practical Applications: Accurate analysis of the scope and claims is vital for licensing, collaboration, and litigation.
