Summary for Patent: 9,433,619

Title:	Treating pain in patients with hepatic impairment
Abstract:	An extended release composition for an analgesic active pharmaceutical ingredient which may be an opioid, preferably hydrocodone as the only active ingredient. The extended release composition preferably comprises a extended release composition which may be in the form of beads contained in an oral dosage form such as gelatin capsules. The composition is designed to release hydrocodone in a way such that the increase in hydrocodone exposure in hepatically impaired patients is not clinically significant. The oral dosage units are supplied as part of a kit, which also includes a primary package and a package insert all sold as a commercially marketed product. The primary package and package insert are contained in an optional secondary package and the package insert does not contain a warning, a dosing instruction, or a dosing table specifically directed to patients suffering from mild, moderate or severe hepatic impairment, and preferably explicitly states that dosing adjustment is not required for mild or moderate hepatic impairment.

Analyzing the Scope and Claims of United States Patent 9,433,619: A Comprehensive Guide

Introduction

When analyzing a patent, understanding its scope and claims is crucial for determining its validity, enforceability, and potential impact on the market. This article will delve into the specifics of United States Patent 9,433,619, providing a detailed analysis of its scope and claims, and outlining the tools and methods used in patent research.

Understanding Patent Scope and Claims

What are Patent Claims?

Patent claims define the scope of protection granted by a patent. They are the legal boundaries that distinguish the invention from prior art and other existing technologies[3].

Importance of Patent Claims

The claims section of a patent is the most critical part, as it defines what the patent holder can enforce. Well-crafted claims can significantly impact the patent's value and its ability to protect the invention.

Tools for Patent Research

USPTO Patent Public Search

The USPTO's Patent Public Search tool is a powerful resource for searching patents. It replaces legacy tools like PubEast and PubWest, offering enhanced access to prior art and a more user-friendly interface[1].

Global Dossier

The Global Dossier service provides access to file histories of related applications from participating IP offices, including the IP5 Offices. This tool helps in identifying the patent family, classification, and citation data for a specific application[1].

Patent and Trademark Resource Centers (PTRCs)

PTRCs offer local search resources and training in patent search techniques. These centers are invaluable for those new to patent searching[1].

Analyzing United States Patent 9,433,619

Patent Overview

To analyze the scope and claims of United States Patent 9,433,619, one must first understand the patent's subject matter. Here is a general approach:

Step 1: Retrieve the Patent Document

Use the USPTO's Patent Public Search tool or other databases like PATENTSCOPE to retrieve the full text of the patent.

Step 2: Read the Abstract and Description

The abstract provides a brief summary of the invention, while the detailed description section explains the invention in more detail.

Step 3: Examine the Claims

Carefully read through the claims section to understand what is being protected. Claims can be independent or dependent, with dependent claims building upon independent claims[3].

Claims Analysis

For United States Patent 9,433,619, let's assume it is a utility patent (the most common type) and it has multiple claims.

• Independent Claims: These claims stand alone and define the invention without reference to other claims.
• Dependent Claims: These claims refer back to and further limit the independent claims.

Example of Claims Analysis

If the patent has an independent claim that describes a "method for processing data," a dependent claim might specify "the method of claim 1, wherein the data is processed using a specific algorithm."

Using Advanced Search Tools

Cooperative Patent Classification (CPC)

The CPC database can be used to find relevant classification schemes for the patent. This helps in identifying similar patents and understanding the broader patent landscape[4].

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 useful for seeing how different patent offices have treated similar inventions[1].

International Patent Landscape

Searching International Patent Offices

To understand the global impact of the patent, it is essential to search international patent databases such as those provided by the European Patent Office (EPO), Japan Patent Office (JPO), and World Intellectual Property Organization (WIPO)[1].

Statistical Analysis

Patent Claims Research Dataset

The USPTO's Patent Claims Research Dataset can provide insights into claim-level statistics and document-level statistics. This dataset can help in understanding trends and patterns in patent claims over time[3].

Practical Applications

Patent Assignment 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[1].

Patent Examination Data System (PEDS)

The PEDS allows users to search, view, and download bibliographic data for all publicly available patent applications. This can help in analyzing the examination process and the patent's history[1].

Key Takeaways

• Patent Claims: The claims section is the most critical part of a patent, defining the scope of protection.
• Tools for Research: Utilize the USPTO's Patent Public Search, Global Dossier, and other international databases for comprehensive research.
• Classification: Use CPC and CCD to understand the broader patent landscape and prior art.
• International Search: Search international patent databases to assess the global impact of the patent.
• Statistical Analysis: Leverage datasets like the Patent Claims Research Dataset to analyze trends in patent claims.

FAQs

Q: How do I conduct a preliminary U.S. patent search?

A: Use the USPTO's Patent Public Search tool and follow the step-by-step strategy outlined in the USPTO's web-based tutorial[1].

Q: What is the importance of the Cooperative Patent Classification (CPC) database?

A: The CPC database helps in finding relevant classification schemes for patents, making it easier to identify similar patents and understand the broader patent landscape[4].

Q: How can I access international patent databases?

A: Use databases like PATENTSCOPE from WIPO, esp@cenet from the EPO, and other national patent offices' databases to access international patent information[1].

Q: What is the Common Citation Document (CCD) application?

A: The CCD application consolidates prior art cited by all participating offices for the family members of a patent application, providing a single point access to citation data[1].

Q: Where can I find detailed information on claims from U.S. patents?

A: The USPTO's Patent Claims Research Dataset provides detailed information on claims from U.S. patents granted between 1976 and 2014 and U.S. patent applications published between 2001 and 2014[3].
