What are INID numbers and why are they important in patent documents?
INID numbers, which stands for “Internationally agreed Numbers for the Identification of (bibliographic) Data,” are codes used to identify various data on the first page of patent documents. As explained in the MPEP:
INID numbers are important because they:
- Allow for easy identification of bibliographic data across different languages
- Facilitate the understanding of patent documents from various countries
- Provide a standardized system for organizing patent information
These codes have been applied to U.S. patents since August 4, 1970, and are now used by most patent offices worldwide.
