This is crucial for understanding the global reach and potential conflicts of the patent[1].
Expiration and Generic Entry
Patent Expiration
- Patents typically have a term of 20 years from the filing date of the earliest non-provisional application to which the patent is entitled. For Patent 5,747,061, the expiration date would be 20 years from its filing date, assuming no extensions or adjustments. Checking the patent status through databases like DrugPatentWatch can provide the exact expiration date and information on generic entry[2].
Search and Analysis Tools
USPTO Resources
- The USPTO offers several tools for searching and analyzing patents, including the Patent Public Search tool, which replaced older tools like PubEast and PubWest. This tool provides enhanced access to prior art and is essential for conducting thorough patent searches[1].
Patent and Trademark Resource Centers (PTRCs)
- Local PTRCs offer training and resources for patent searching. They can provide guidance on using advanced search techniques and accessing various databases, which can be invaluable when analyzing a specific patent like 5,747,061[1].
Advanced Search Techniques
Cooperative Patent Classification (CPC)
- Using the CPC database can help in finding relevant classification schemes for the patent. This classification system is used internationally and can aid in identifying similar patents and prior art[4].
Full-Text Searching
- Full-text searching of patent grants and applications through databases like PATENTSCOPE and the worldwide database from the EPO can provide detailed information on the patent and related documents. Machine translation features can also help in analyzing patents from different countries[4].
Legal and Regulatory Aspects
Office Actions and Patent Family
- Tools like the Global Dossier and the CCD can help in identifying office actions and the patent family for a specific application. This information is crucial for understanding the legal status and any potential challenges to the patent[1].
