This article will delve into the specifics of United States Patent 6,352,717, titled "Process for encapsulating shear sensitive fill masses into capsules," and provide a detailed analysis of its scope, claims, and the broader patent landscape.
Overview of the Patent
Title and Abstract
United States Patent 6,352,717, granted on March 5, 2002, describes a process for encapsulating shear-sensitive fill masses into capsules. The patent focuses on a method to protect sensitive materials during the encapsulation process, ensuring the integrity and efficacy of the final product.
Inventors and Assignees
The patent was invented by a team of researchers and assigned to a pharmaceutical company. Understanding the inventors and assignees can provide insights into the development and commercialization of the technology.
Scope of the Patent
Technical Background
The patent addresses a specific challenge in pharmaceutical manufacturing: the encapsulation of shear-sensitive materials. Shear sensitivity refers to the tendency of materials to degrade or lose their properties when subjected to mechanical stress, such as during the encapsulation process. The patented process aims to mitigate this issue through a novel method of encapsulation.
Claims
The claims of a patent define the scope of the invention and what is protected by the patent. For US Patent 6,352,717, the claims can be broadly categorized into:
Independent Claims
These claims stand alone and define the core invention. They typically include the essential features of the process, such as the specific steps involved in encapsulating the shear-sensitive fill masses.
Dependent Claims
These claims build upon the independent claims and provide additional details or variations of the invention. They may include specific materials, equipment, or conditions under which the process is carried out.
Claim Analysis
To understand the scope of the patent, it is essential to analyze each claim carefully. Here are some key aspects to consider:
Claim Coverage Matrix
Using a Claim Coverage Matrix, as described by Schwegman’s process, can help categorize the claims by their scope concepts. This matrix can identify which claims are actively protecting the intellectual property and where gaps or opportunities exist[3].
Scope Concepts
The claims can be categorized by overarching scope concepts, such as the type of fill mass, the encapsulation method, and the equipment used. This categorization helps in filtering, searching, and analyzing large numbers of patent claims concurrently[3].
Patent Landscape Analysis
Priority Patent Applications
To understand the broader patent landscape, it is crucial to identify the priority patent applications related to US Patent 6,352,717. This involves searching databases like Esp@ceNet, which compiles application numbers, dates, and applicants from over 70 million patent documents worldwide[1].
Patent Families
The priority patent data is used to search for the corresponding patent families. A patent family includes similar patent documents filed in different jurisdictions, all deriving from the same priority patent application. This helps in tracking where else in the world similar patent applications have been filed and granted[1].
Regional and National Patent Offices
The patent status at regional and national patent offices, such as the USPTO, EPO, or other relevant offices, needs to be verified. This ensures that the patent is valid and enforceable in various jurisdictions.
Transparency and Accessibility of Patent Information
Publicly Available Lists
Patent information, including that related to US Patent 6,352,717, is publicly available through databases like the US FDA Orange Book and Health Canada Patent Registry. These databases provide detailed information on approved pharmaceutical products and the patents claimed as relevant to them[1][2].
Esp@ceNet and INPADOC
Databases like Esp@ceNet and INPADOC are essential tools for patent searches. Esp@ceNet provides free access to patent information from over 70 million patent documents worldwide, while INPADOC compiles patent family information for about 95% of all published patents globally[1].
Limitations and Challenges
Methodology Limitations
The methodology for determining the patent landscape and analyzing claims has its limitations. For instance, the accuracy of the data depends on the quality of the sources and the thoroughness of the search. Cross-checking data from multiple sources is crucial to ensure accuracy[1].
Interpretation of Claims
Interpreting patent claims can be complex and may require legal and technical expertise. The scope of the claims must be carefully analyzed to avoid infringement and to identify potential gaps in coverage[3].
