Analyzing the Scope and Claims of United States Patent 10,294,242: A Comprehensive Guide
Introduction
Understanding the scope and claims of a patent is crucial for inventors, researchers, and businesses to navigate the complex landscape of intellectual property. This article will delve into the specifics of United States Patent 10,294,242, titled "Diaryl macrocycle polymorph," and provide a detailed analysis of its scope, claims, and the broader patent landscape.
Overview of the Patent
Patent Number and Title
United States Patent 10,294,242, titled "Diaryl macrocycle polymorph," was granted on May 21, 2019. This patent pertains to a specific polymorph form of a compound, which is significant in pharmaceutical applications.
Publication Number and Authority
The patent has the publication number US10294242B2 and is authorized by the United States Patent and Trademark Office (USPTO)[4].
Claims Analysis
Independent and Dependent Claims
The patent includes both independent and dependent claims. Independent claims define the broadest scope of the invention, while dependent claims narrow down the scope by adding additional limitations.
-
Independent Claims: These claims outline the core aspects of the invention, such as the specific polymorph form of the compound and its pharmaceutical composition. For example, Claim 1 might describe the polymorph form 1 of Compound I, including its formula and structural characteristics[4].
-
Dependent Claims: These claims build upon the independent claims by adding specific details or limitations. For instance, a dependent claim might specify the method of preparation or the use of the polymorph form in a particular therapeutic application.
Claim Language and Scope
The language used in the claims is critical in defining the patent's scope. Longer independent claims and a higher count of independent claims can indicate a broader scope, although this can also lead to issues of clarity and validity[3].
Patent Scope Metrics
Independent Claim Length and Count
Research suggests that metrics such as independent claim length and 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].
Patent Maintenance Payments and Forward Citations
The scope of a patent can also be inferred from maintenance payments and forward citations. Patents with narrower claims tend to have higher maintenance payments and more forward citations, indicating their relevance and impact in the field[3].
Prior Art and Citation Data
Common Citation Document (CCD)
The Common Citation Document (CCD) application consolidates prior art cited by all participating IP5 Offices for the family members of a patent application. This tool helps in visualizing the search results for the same invention produced by several offices on a single page, which is crucial for understanding the prior art landscape related to the patent[1].
Global Dossier
The Global Dossier service provides access to the file histories of related applications from participating IP Offices. This includes the patent family for a specific application, along with dossier, classification, and citation data. This service helps in identifying office actions and other relevant information that can impact the scope and validity of the patent[1].
International Patent Landscape
Searchable Databases
To understand the global patent landscape, it is essential to search databases from other International Intellectual Property offices. Resources such as the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO) provide access to international patent databases, including machine translations for some documents[1].
Practical Implications
Patent Examination and Litigation
The scope and claims of a patent can significantly impact its examination process and potential litigation. Broader claims may face more scrutiny and challenges during the examination process, while narrower claims may have a smoother path to grant but could be less protective of the invention[3].
Licensing and Innovation
The clarity and validity of patent claims also affect licensing and innovation. Patents with overly broad or unclear claims can lead to increased licensing and litigation costs, which can diminish incentives for innovation[3].
Tools and Resources for Patent Search
Patent Public Search
The USPTO's Patent Public Search tool provides enhanced access to prior art with modern interfaces. This tool is essential for conducting thorough searches to ensure the novelty and non-obviousness of the invention[1].
Patent and Trademark Resource Centers (PTRCs)
Local PTRCs offer training in patent search techniques and maintain local search resources, which can be invaluable for inventors and researchers[1].
Conclusion
Understanding the scope and claims of United States Patent 10,294,242 involves a detailed analysis of its independent and dependent claims, prior art, and the broader international patent landscape. Tools like the Common Citation Document and Global Dossier are crucial for navigating this landscape. The metrics of independent claim length and count provide insights into the patent's scope and its potential impact on the examination process and innovation.

FAQs
What is the significance of independent claim length and count in patent scope?
Independent claim length and count are metrics that help measure the breadth of a patent. Narrower claims at publication are associated with a higher probability of grant and a shorter examination process[3].
How does the Global Dossier service help in patent searching?
The Global Dossier service provides access to the file histories of related applications from participating IP Offices, including the patent family, dossier, classification, and citation data. This helps in identifying office actions and other relevant information[1].
What are the practical implications of broader versus narrower patent claims?
Broader claims may face more scrutiny during the examination process, while narrower claims may have a smoother path to grant but could be less protective of the invention. Clear and valid claims are essential for minimizing licensing and litigation costs and promoting innovation[3].
How can one search for international patent databases?
Resources such as the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO) provide access to international patent databases. These databases often include machine translations for some documents[1].
What is the role of the Common Citation Document (CCD) in patent searching?
The CCD consolidates prior art cited by all participating IP5 Offices for the family members of a patent application, allowing users to visualize the search results on a single page. This tool is part of the ongoing process of technical harmonization at the international level[1].
