Agent Country Field (AGTCN)
Use the Agent Country field code to search for patents and applications where the agent or attorney is from a particular country. The field code is AGTCN.
Note - Use the standard, two-digit ISO 3166 country code in the AGTCN field. In other words, if you want to pull up documents from agents in France, use FR. Using France will not return any results.
Examples
- AGTCN:CN --> Finds documents where the agent is located in China.
- ANO:IBM and AGTCN:TW --> Finds IBM patents that were prosecuted by patent agents or attorneys from Taiwan.
- AGTCN:TV --> Confirms your suspicion that no US patent has ever been filed from a resident of Tuvalu.
