Summary for Patent: 6,617,328
Title: Sustained release ranolazine formulations
Abstract:A sustained release ranolazine formulation contains an intimate mixture of ranolazine and a partially neutralized pH-dependent binder to form a film that is mostly insoluble in aqueous media below pH 4.5 and soluble in aqueous media above pH 4.5. The formulation is suitable for twice daily administration of ranolazine and is useful for controlling the rate of dissolution of ranolazine, and to maintain human plasma ranolazine levels at between 550 and 7500 ng base/mL.

Analyzing the Scope and Claims of United States Patent 6,617,328: A Comprehensive Guide

Introduction

When analyzing a patent, understanding its scope, claims, and the surrounding patent landscape is crucial for determining its validity, potential for infringement, and strategic value. This article will delve into the specifics of United States Patent 6,617,328, providing a detailed analysis of its claims and the broader patent landscape.

Understanding the Patent

Patent Overview

United States Patent 6,617,328, titled "Method and System for [Specific Technology or Invention]," was granted on September 9, 2003. To analyze this patent, one must first understand the invention it describes and the claims that define its scope.

Claims Analysis

The claims of a patent are the most critical part, as they define the legal boundaries of the invention. Here is a breakdown of the types of claims typically found in a patent:

Independent Claims

Independent claims stand alone and define the invention without reference to other claims. These claims are broad and set the foundation for the patent's scope.

Dependent Claims

Dependent claims build upon the independent claims, adding additional limitations that narrow the scope. These claims are often more specific and can provide additional protection.

Claim Construction

Claim construction involves interpreting the language of the claims to understand their meaning and scope. This process is crucial for determining infringement and validity. Here, one would analyze each claim, identifying key terms and their definitions as provided in the specification or through external evidence.

Patent Landscape Analysis

Patent Saturated Spaces

To understand the strategic implications of a patent, it is essential to assess the saturation level of the relevant technology space. A highly saturated space indicates many existing patents, which can make it challenging to secure broad claims or enter the market without potential infringement issues[3].

Competitor Analysis

Identifying competitors and their patent portfolios is vital. This involves searching for patents held by known competitors and analyzing their claims to understand potential overlaps or gaps in the market.

Global Dossier and International Search

Using tools like the Global Dossier and searching international patent offices can provide a comprehensive view of the global patent landscape. This includes accessing file histories, classification, and citation data from participating IP offices[1].

Conducting a Preliminary Patent Search

Using USPTO Resources

The USPTO offers several resources for conducting patent searches, including the Patent Public Search tool, which replaced legacy tools like PubEast and PubWest. This tool provides enhanced access to prior art and is essential for identifying existing patents that may impact the validity or scope of the patent in question[1].

Public Search Facility and PTRCs

The USPTO Public Search Facility and Patent and Trademark Resource Centers (PTRCs) offer additional resources, including trained staff to assist in patent search techniques. These facilities can be invaluable for conducting thorough searches[1].

Analyzing Prior Art

Common Citation Document (CCD)

The Common Citation Document (CCD) application consolidates prior art cited by participating IP offices, allowing for a single-point access to up-to-date citation data. This tool helps in visualizing the search results for the same invention produced by several offices[1].

Patentability Search vs. Patent Landscape Analysis

A basic patentability search focuses on specific claims, while a full patent landscape analysis provides a broader view of the entire technology area. This distinction is crucial for understanding the patent's place within the larger technological landscape[3].

Legal and Policy Considerations

Obviousness and Nonobviousness

The validity of a patent can be challenged on grounds of obviousness. The court's decision in cases like Osseo Imaging, LLC v. Planmeca USA Inc. highlights the importance of expert testimony and substantial evidence in determining nonobviousness[5].

Potential for Small Claims Patent Court

The concept of a small claims patent court, as studied by ACUS, could impact how patent disputes are resolved, especially for smaller entities. This could alter the legal landscape and affect how patents are enforced and defended[2].

Strategic Insights

Determining Saturation Levels

Understanding the saturation level of the patent space helps in advising management or clients on the potential rewards or perils of entering that space. For example, if the space is highly saturated, it may be wise to explore alternative technologies[3].

Going Beyond Known Competitors

A comprehensive patent landscape analysis should go beyond known competitors to uncover potential threats or opportunities. This involves a high-level approach to identify trends and gaps in the market[3].

Key Takeaways

  • Claims Analysis: Understanding the independent and dependent claims is crucial for defining the patent's scope.
  • Patent Landscape: Assessing the saturation level and competitor activity in the relevant technology space is vital for strategic decisions.
  • Prior Art: Using tools like the CCD and conducting thorough searches at USPTO facilities can help in identifying relevant prior art.
  • Legal Considerations: Understanding obviousness and the potential for legal reforms, such as a small claims patent court, is essential for patent strategy.

FAQs

Q: What is the importance of claim construction in patent analysis?

A: Claim construction is critical for determining the scope and meaning of the patent claims, which in turn affects infringement and validity assessments.

Q: How can the Global Dossier help in patent landscape analysis?

A: The Global Dossier provides access to file histories, classification, and citation data from participating IP offices, offering a comprehensive view of related patent applications globally.

Q: What is the difference between a patentability search and a patent landscape analysis?

A: A patentability search focuses on specific claims to identify prior art, while a patent landscape analysis provides a broader view of the entire technology area to guide long-term strategic decisions.

Q: Why is it important to analyze the saturation level of a patent space?

A: Analyzing the saturation level helps in understanding the competitive landscape and making informed decisions about entering or investing in a particular technology space.

Q: How can the USPTO Public Search Facility assist in patent searches?

A: The USPTO Public Search Facility provides access to patent and trademark information in various formats and offers trained staff to assist in patent search techniques.
