Release for data update 06/30/2020

Data Changes

1. H patents are temporarily removed from the database awaiting reparsing. Currently, H patent numbers are incorrectly loaded with the corresponding check digits (from the raw data) loaded as part of the patent number. The data has been reparsed to remove erraneous mapping and will be added to the database for the next update
2. Claims data has been reparsed to include newlines in the text and improved dependent field extraction has been implemented. Data from 1976 - 2000 (newlines, dependent field improvement) and 2005 - 2020 (newlines) has been posted on the bulk download page. Data from 2001 -2004 is being processed and will be posted as and when they become available

Pregrant Publications Data

1. A beta version of USPTO's pre-grant publication data is now available at : www.patentsview.org/download/pregrantpublications.html. Users should note that this is pre-release product and may be missing data elements. We encourage users to report any issues that they find in the data.

API Changes

1. The API has moved to the Amazon's Beanstalk platform and consequently the URL has changed. The new URL is https://api.patentsiew.org/. Previous URLs will redirect to the new URL, but POST requests will not work. The redirection is a temporary failsafe and users should update their URL to the updated URL.

Querytool Changes

1. In an effort to reduce the delay in communication during a Querytool failure, we have implemeted an email alert system. We hope to utilize this system to be bit more quicker in resolving any errors that the Querytool may face.
