International Patent Family
To understand the global reach of this invention, it is essential to look at the international patent family. The Global Dossier service provided by the USPTO allows users to see the patent family for a specific application, including related applications filed at participating IP Offices. This service helps in identifying whether similar patents were granted in other countries and the status of those patents[1].
Expiration and Public Domain
Since the patent has expired, the inventions described in US 7,511,041 B2 are now in the public domain. This means that anyone can use, manufacture, and sell the fused azole-pyrimidine derivatives without infringing on the original patent. However, it is crucial to ensure that no other patents covering similar inventions are still in force.
Search and Analysis Tools
For a comprehensive analysis of the patent landscape, several tools and resources are available:
Patent Public Search
The USPTO's Patent Public Search tool is a powerful resource for searching prior art and understanding the patent landscape. It provides enhanced access to prior art and allows users to search through a vast database of patents and patent applications[1].
Global Dossier
The Global Dossier service is useful for viewing the file histories of related applications from participating IP Offices. This helps in identifying the global patent family and understanding the status of related patents[1].
Common Citation Document (CCD)
The CCD application consolidates prior art cited by all participating offices for the family members of a patent application. This tool is essential for visualizing the search results for the same invention produced by several offices on a single page[1].
Economic and Research Implications
The Patent Claims Research Dataset provided by the USPTO can offer insights into the economic and research implications of patents like US 7,511,041 B2. This dataset contains detailed information on claims from US patents and patent applications, which can be used to analyze trends and scope measurements in patenting activities[3].
Conclusion
United States Patent 7,511,041 B2 represents a significant contribution to the field of pharmaceutical chemistry, particularly in the area of fused azole-pyrimidine derivatives. Understanding the scope, claims, and patent landscape of this invention is crucial for researchers, manufacturers, and legal professionals.
