According to MPEP 901.07 , there are key differences in how USPTO examiners use the World Patents Index (WPI) and International Patent Documentation Center (INPADOC) databases: WPI : Preferred for more comprehensive searches. The MPEP states: WPI in-house is used whenever abstracts are needed or when searches in addition to publication date or patent family are required, such as searches on inventor name or IPC (International Patent Classification). INPADOC : Used for faster, more focused searches. As per the MPEP: INPADOC is used for quick searches for publication dates or patent families. WPI is integrated with the USPTO’s automated search system and is often the first choice due to its ease of use and low cost, especially for searches involving abstracts or additional criteria beyond publication dates and patent families.
