Date

You can restrict your search to a range of publicationapplication or priority dates.

Four options are available: FromUp To, Between and On.

Enter the date or dates in the format YYYY-MM-DD or use the calendar tool.

If you have other search criteria, the date will be combined with the other criteria using the AND operator.

FamPat records may contain multiple family members and thus contain multiple publication, priority and application dates for one invention.

The Publication Date searches first or earliest publication date for each patent office family member filing.

The Application Date searches the application date for all family members.

The Priority Date searches all priority dates in the family record.

In the Fullpat and FullText collections, searching by date is done on the application (filing) date of the publication, on the priority date of the publication and the publication date of publication. 

For Fullpat , the publication date relates to the publication dates of all publication steps.  

For FullText , the publication search date relates only to the publication of the patent's Fulltext.
