Summary for Patent: RE30633
Title: 3-Lower alkylcarbamylsulfonamido-4-phenylaminopyridines, n-oxides, derivatives thereof and pharmaceutical compositions containing same
Abstract:This invention relates to new derivatives of pyridine having anti-inflammatory and diuretic properties. The new derivatives of pyridine may be represented by the following general formula: ##STR1## in which X represents an amino, C.sub.1 -C.sub.4 -alkylamino, oxy or thio group, R.sub.1 represents a group of the formula R.sub.3 NHCA (II), wherein A represents oxygen or sulfur, and R.sub.3 represents a C.sub.1 -C.sub.4 -alkyl, alkenyl, cycloalkyl, phenyl (which may be substituted) or R.sub.4 CO (III) group, R.sub.4 representing a phenyl group (which may be substituted), R.sub.2 represents hydrogen or a C.sub.1 -C.sub.4 alkyl group and Z represents a C.sub.1 -C.sub.4 -alkyl, methylfuryl, pyridyl or phenyl group (which may be substituted). This invention relates also to the N-oxides of the compounds of formula I, as well as to the acid and base addition salts of said compounds.

Analyzing the Scope and Claims of a U.S. Patent: A Detailed Guide Using the Example of U.S. Patent RE30633

Introduction

When analyzing the scope and claims of a U.S. patent, it is crucial to understand the intricacies of patent law, the tools available for searching and analyzing patents, and the specific details of the patent in question. This article will provide a comprehensive guide using U.S. Patent RE30633 as an example.

Understanding Patent Claims

Importance of Claims

Patent claims are the heart of a patent application, defining the scope of the patent's protection. They outline what the inventor considers to be the novel and non-obvious aspects of the invention[5].

Types of Claims

Claims can be independent or dependent. Independent claims stand alone and define the invention, while dependent claims refer back to and further limit an independent claim[5].

Tools for Patent Searching and Analysis

Patent Public Search

The USPTO's Patent Public Search tool is a powerful resource for searching prior art and analyzing patent claims. It offers two modern interfaces that enhance access to prior art and improve the overall patent searching process[1].

Global Dossier

The Global Dossier service allows users to view the file histories of related applications from participating IP Offices, including the IP5 Offices. This is useful for understanding the global patent landscape and identifying office actions and other relevant data[1].

Cooperative Patent Classification (CPC)

The CPC database is essential for finding relevant classification schemes. It helps in categorizing patents and applications, making it easier to search and analyze patents within specific technological areas[4].

Analyzing U.S. Patent RE30633

Patent Details

To analyze U.S. Patent RE30633, one would start by retrieving the patent document from the USPTO's database or other patent search tools like Patent Public Search or PATENTSCOPE.

Reading the Claims

The claims section of the patent is where the inventor defines the invention. For example, in a patent like RE30633, one would look at the independent claims first to understand the core of the invention. Then, analyze the dependent claims to see how they further limit and specify the invention.

Claim Construction

Claim construction is a critical step in understanding the scope of a patent. This involves interpreting the language of the claims to determine what is covered by the patent. This process can be complex and often involves legal and technical expertise[2].

Prior Art and Novelty

To assess the novelty and non-obviousness of the invention, one must conduct a thorough search of prior art. Tools like the Common Citation Document (CCD) and the Patent Public Search can help consolidate and visualize prior art cited by various patent offices[1].

Patent Landscape Analysis

Global Patent Family

Using the Global Dossier service, one can identify all related applications filed at participating IP Offices. This helps in understanding the global reach and protection of the patent[1].

Office Actions and Prosecution History

Analyzing office actions and the prosecution history of the patent can provide insights into how the patent was granted and any challenges or rejections faced during the application process. The Patent Examination Data System (PEDS) can be useful for accessing this information[1].

Citation Data

The Common Citation Document (CCD) application provides a single point of access to citation data from multiple patent offices. This helps in understanding how different offices have treated the same invention, which can be crucial for assessing the strength and scope of the patent[1].

Statistical Analysis of Patent Claims

Patent Claims Research Dataset

The USPTO's Patent Claims Research Dataset can provide detailed statistical insights into patent claims. This dataset includes information on claims from U.S. patents granted between 1976 and 2014 and U.S. patent applications published between 2001 and 2014. It can help in understanding trends and measurements of patent scope[3].

Practical Steps for Analysis

Step-by-Step Search Strategy

Conducting a preliminary U.S. patent search involves several steps:

  • Use the Patent Public Search tool to search for existing patents and published patent applications.
  • Utilize the Cooperative Patent Classification (CPC) database to categorize and narrow down the search.
  • Review the Global Dossier for related applications and file histories.
  • Analyze office actions and prosecution history through PEDS[1][4].

Training and Resources

The USPTO and other resources like Patent and Trademark Resource Centers (PTRCs) offer training materials and tutorials to help with advanced patent searching and analysis[1][4].

Legal Considerations

Claim Construction Disputes

Claim construction disputes, such as those seen in the Lite-Netics LLC v. Nu Tsai Capital LLC case, highlight the importance of clear and specific claim language. These disputes often require detailed legal and technical analysis to resolve[2].

Prosecution History Estoppel

Understanding prosecution history estoppel is crucial when analyzing patent claims. This doctrine can limit the scope of a patent based on amendments made during the prosecution process[5].

Key Takeaways

  • Claims Define the Patent: The claims section is the most critical part of a patent application, defining the scope of protection.
  • Use Advanced Search Tools: Tools like Patent Public Search, Global Dossier, and CPC database are essential for thorough patent analysis.
  • Analyze Prior Art: Understanding prior art is vital for assessing the novelty and non-obviousness of an invention.
  • Legal Considerations: Claim construction, prosecution history estoppel, and office actions are key legal aspects to consider.
  • Statistical Insights: Datasets like the Patent Claims Research Dataset can provide valuable statistical insights into patent claims.
