Understanding the Scope and Claims of United States Patent 9,174,975

Introduction

When analyzing a patent, particularly one like United States Patent 9,174,975, it is crucial to delve into its various components to understand its scope, claims, and position within the broader patent landscape. This article will guide you through the key elements of this patent, using relevant examples and explanations.

Patent Structure

To begin, let's break down the typical structure of a U.S. patent, which includes several critical sections:

Front Page and Bibliographic Data

The front page of a patent contains essential bibliographic data identified by INID codes. For U.S. Patent 9,174,975, this would include the document number, document type, application number, date of application, date of patent, IPC classification, and national classification[1].

Drawings

The drawings section illustrates the technical details of the invention. These drawings must conform to specific drafting guidelines and provide enough detail for anyone with ordinary skill in the same technical field to understand the invention[1].

Specification

The specification is a written description of the invention, including discussions of prior art, descriptions of the drawings, how the invention solves a technical problem, and the preferred embodiment of the invention. This section must be detailed enough for someone skilled in the field to replicate the invention[1].

Claims

The claims section defines the scope of protection for the patent. Claims are the legal boundaries of the invention and must be clear and specific. The first claim sets the foundation for the rest, and subsequent claims can be dependent on the first claim[1].

Claims Analysis of U.S. Patent 9,174,975

Claim Structure

U.S. Patent 9,174,975, related to pharmaceuticals, would have claims that define the specific methods, compositions, or uses protected by the patent. For example, if this patent is related to a method of treating a condition, the claims would outline the specific steps, dosages, and compounds involved.

Independent and Dependent Claims

Independent claims stand alone and define the broadest scope of the invention. Dependent claims build upon independent claims and narrow down the scope. For instance, an independent claim might describe a method of treating schizophrenia, while a dependent claim might specify a particular dosage or administration route[1].

Claim Scope and Coverage

The scope of the claims determines what is protected by the patent. In the case of U.S. Patent 9,174,975, if it covers methods of treating patients with an antipsychotic without significant weight gain, the claims would specify the exact conditions, dosages, and administration methods that are protected[2].

Patent Landscape and Analytics

Patent Family and Global Dossier

Understanding the patent family and using tools like the Global Dossier can provide insights into related applications filed at participating IP offices. This helps in identifying the broader patent landscape and any potential gaps or opportunities[4].

Claim Coverage Matrix

A Claim Coverage Matrix can help in categorizing patents by claims and scope concepts, making it easier to analyze large numbers of patent claims. This tool is particularly useful for identifying which patents and claims are actively protecting the intellectual property and where gaps or opportunities exist[3].

Common Citation Document (CCD)

The CCD application consolidates prior art cited by all participating offices for the family members of a patent application. This tool is essential for visualizing search results for the same invention produced by several offices on a single page[4].

Intellectual Property Rights and Enforcement

Patent Assignments and Ownership

Understanding who owns the patent and any changes in ownership is crucial. The Patent Assignment Search website can be used to search for patent assignments and changes in ownership, which is vital for enforcing intellectual property rights[4].

Litigation and Infringement

Patents like U.S. Patent 9,174,975 can be involved in litigation if there are allegations of infringement. For example, if a generic version of a drug covered by this patent is developed, the patent holder may take legal action to protect their rights[2].

Key Takeaways

• Patent Structure: Understand the front page, drawings, specification, and claims sections.
• Claims Analysis: Identify independent and dependent claims and their scope.
• Patent Landscape: Use tools like Global Dossier and Claim Coverage Matrix to analyze related patents.
• Intellectual Property Rights: Keep track of patent assignments and be prepared for potential litigation.
