Analyzing the Scope and Claims of United States Patent 5,246,714: A Comprehensive Guide
Introduction
Understanding the scope and claims of a patent is crucial for inventors, businesses, and legal professionals. This article will delve into the details of United States Patent 5,246,714, providing a thorough analysis of its scope, claims, and the broader patent landscape.
Background of the Patent
United States Patent 5,246,714, titled "Controlled Release Means," was granted to its inventors for a specific innovation in the field of pharmaceuticals. To analyze this patent, we need to understand its context, claims, and the technological area it pertains to.
Patent Search and Retrieval
To begin, one can use the USPTO's Patent Public Search tool or other resources like the Patent and Trademark Resource Centers (PTRCs) to retrieve the patent details. The Patent Public Search tool provides enhanced access to prior art and allows users to search through issued patents and published patent applications[1].
Patent Claims
The claims section of a patent is the most critical part, as it defines the scope of the invention. For US Patent 5,246,714, the claims would outline the specific controlled release means described in the patent. Here are some key points to consider:
Independent Claims
Independent claims are standalone claims that do not rely on other claims. They define the broadest scope of the invention. For example, Claim 1 might describe the overall controlled release system, including its components and how they interact.
Dependent Claims
Dependent claims build upon independent claims and provide more specific details. These claims narrow down the scope by adding additional features or limitations. For instance, Claim 2 might specify a particular material used in the controlled release system.
Claim Construction
Understanding the claim construction is vital. This involves interpreting the language used in the claims to determine the exact scope of protection. The USPTO's Patent Claims Research Dataset can provide insights into claim-level statistics and document-level statistics, which can be useful in analyzing claim construction trends[3].
Patent Scope
The scope of a patent is defined by its claims but also influenced by the description and drawings provided in the patent specification. Here’s how to analyze the scope:
Description and Drawings
The description section explains the invention in detail, including its background, summary, and detailed description. The drawings illustrate the invention and help in understanding its components and how they work together.
Prior Art
Prior art refers to existing knowledge and inventions in the field that predate the patent application. The Common Citation Document (CCD) application can be used to consolidate prior art cited by multiple patent offices, helping to understand the novelty and non-obviousness of the invention[1].
Technological Context
Understanding the technological context in which the patent was granted is essential. For US Patent 5,246,714, the controlled release means are likely part of the broader field of pharmaceutical delivery systems.
