Searchable Datafields
In Google Patent Search, any search terms entered without field qualifiers will automatically be run through the entire full text patent records. To narrow the scope of a search, the following data fields can be searched from the advanced search form, or by using field qualifying operators:
- Patent Number
- Title
- Inventor
- Assignee
- US Classification
- IPC Classification
- Issue date (range only – months but not days specified)
- Filing date (range only – months but not days specified)
A number of operators are available to allow users to denote certain fields when using the quick search bar. These are listed below:
- Patent Number: “Patent:”
- Inventor: “ininventor:”
- Assignee: “inassignee:”
- US Classification: “uspclass:”
- International Classsification: “intlpclass:”
Date ranges can be searched by using the phrase (between MM/YYYY and MM/YYYY) where the two dates specify a date range. (The phrase should not be enclosed in quotes, as the system will then interpret it as a phrase search.)
