Summary for Patent: 6,102,254
Title: Pharmaceutical compositions in semisolid form and a device for administration thereof
Abstract:A pharmaceutical delivery system for oral administration of a pharmaceutical agent comprises: (a) a squeezable container having an outlet defining a flow channel, (b) a channel closure device adapted to selectively close or open the flow channel; and (c) within the container, at least one dose of a pharmaceutical composition, the composition being a semisolid material that is storage stable, and consists of mutually compatible components, the components comprising (i) an effective amount of an orally active pharmaceutical agent useful for systemic treatment, and (ii) a palatable pharmaceutically acceptable vehicle, comprising a liquid base selected from the group consisting of water, propylene glycol, polyethylene glycol, glycerin, and mixtures thereof, a thickening agent selected from the group consisting of starch, modified starch, sodium carboxymethyl cellulose, microcrystalline cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, other cellulose derivatives, acacia, tragacanth, pectin, gelatin, polyethylene glycol, and water-soluble carboxyvinyl polymers, the pharmaceutical composition having a consistency which allows the composition to be squeezed by manual pressure through the flow channel, whereby in response to pressure on the container when the flow channel is open, a predetermined unit dose of the pharmaceutical composition can be easily squeezed from the container into a receptacle, measured, and administered orally without spilling any of the composition from the container or the receptacle.

Understanding the Scope and Claims of a Patent: A Detailed Analysis of United States Patent 6,102,254

Introduction to Patent Analysis

When analyzing a patent, it is crucial to understand the scope and claims, as these elements define the intellectual property rights granted to the patent holder. Here, we will delve into the specifics of United States Patent 6,102,254, exploring its claims, scope, and the broader patent landscape.

What is United States Patent 6,102,254?

To begin, let's identify the patent in question. United States Patent 6,102,254 is a specific patent that has been granted by the United States Patent and Trademark Office (USPTO). However, since the exact details of this patent are not provided in the sources, we will use general principles of patent analysis to guide our discussion.

How to Find the Patent

To analyze a patent, you first need to locate it. The USPTO provides several tools for this purpose:

  • Patent Public Search: This is a powerful web-based tool that replaced older search tools like PubEast and PubWest. It offers enhanced access to prior art and is a primary resource for finding patents[1].
  • Global Dossier: This service allows users to see the patent family for a specific application, including related applications from participating IP Offices[1].

Understanding Patent Claims

Independent and Dependent Claims

Patent claims are the heart of a patent, defining the scope of the invention. There are two types of claims: independent and dependent.

  • Independent Claims: These claims stand alone and define the invention without reference to other claims. They are crucial in determining the scope of the patent[3].
  • Dependent Claims: These claims refer back to and further limit an independent claim. They often add specific details or variations to the independent claims.

Metrics for Measuring Patent Scope

Research has shown that metrics such as independent claim length and independent claim count can be used to measure patent scope. Narrower claims at publication are associated with a higher probability of grant and a shorter examination process[3].

Analyzing the Scope of the Patent

Claim Language and Breadth

The scope of a patent is determined by the language used in the claims. Broader claims may cover a wider range of variations, but they are also more likely to face challenges during the examination process. Narrower claims, while more specific, may have a higher chance of being granted but offer less protection against competitors.

Prior Art and Novelty

The novelty of the invention is a critical factor in determining the scope of the patent. The Common Citation Document (CCD) application helps consolidate prior art cited by multiple offices, making it easier to assess the novelty and non-obviousness of the invention[1].

Patent Landscape and Related Applications

Global Patent Family

Using tools like the Global Dossier, you can identify the patent family for a specific application. This includes all related applications filed at participating IP Offices, providing a comprehensive view of the global patent landscape[1].

International Patent Offices

To see if an idea has been patented abroad, you need to search databases from other international intellectual property offices. Resources like the European Patent Office (EPO), Japan Patent Office (JPO), and World Intellectual Property Organization (WIPO) provide access to international patent databases[1].

Search and Examination Process

Preliminary Search

Conducting a preliminary search is essential before filing a patent application. The USPTO offers a step-by-step strategy for this process, including using the Patent Public Search tool and consulting resources like the Patent and Trademark Resource Centers (PTRCs)[1].

Examination Data

The Patent Examination Data System (PEDS) allows public users to search, view, and download bibliographic data for all publicly available patent applications. This can provide insights into the examination process and the history of the patent[1].

Case Study: Analyzing a Pharmaceutical Patent

To illustrate the process, let's consider a pharmaceutical patent like the one for an ibuprofen suspension (CA 2486553). Here, the patent claims would define the specific formulation and method of administration. The scope would include the type of active ingredient, the suspension-stabilizing vehicle, and any specific manufacturing processes.

  • Claims: The claims would specify the exact composition and method of preparing the ibuprofen suspension.
  • Scope: The scope would cover the use of the suspension for oral administration, including the effective amount of the active ingredient and the pharmaceutically acceptable vehicle.
  • Prior Art: The CCD application would help identify any prior art cited by other offices, ensuring the novelty of the invention.
  • Global Landscape: The Global Dossier would show related applications filed in other countries, providing a global view of the patent family[4].

Key Takeaways

  • Claims Define Scope: The claims in a patent are crucial in defining the scope of the invention.
  • Metrics for Scope: Independent claim length and count can be used to measure patent scope.
  • Global Search: Searching international patent databases is essential to understand the global patent landscape.
  • Examination Process: Tools like PEDS provide insights into the examination history of a patent.
  • Novelty and Prior Art: Ensuring the novelty of the invention by analyzing prior art is vital.

FAQs

Q: How do I find a specific patent?

A: You can use the USPTO's Patent Public Search tool or the Global Dossier service to locate a specific patent.

Q: What is the difference between independent and dependent claims?

A: Independent claims stand alone and define the invention, while dependent claims refer back to and further limit an independent claim.

Q: How do I measure the scope of a patent?

A: Metrics such as independent claim length and independent claim count can be used to measure patent scope.

Q: Why is it important to search international patent databases?

A: Searching international databases helps to identify related applications and understand the global patent landscape.

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

A: The CCD application consolidates prior art cited by multiple offices, helping to assess the novelty and non-obviousness of the invention.
