Data Updates

How often is the data updated?  Annually, Quarterly, Monthly, Weekly?

When is it updated (e.g, Annually, by January of next year; Quarterly within two weeks of end of previous quarter)?

How often is computed data updated, specifically the disambiguity algorithm?  Is this update global or a delta update (do you create new assignment matches starting from scratch or do you use previous results to match to based on only the new patent information)?

Thanks!

DATA UPDATES

Hi mshaffer,

This recent post describes seems to answer your question (Link here: http://www.patentsview.org/community/forum/generalfaq)

"

HOW FREQUENTLY ARE THE DATA DRIVING THE PATENTSVIEW DATABASE UPDATED?

The PatentsView database is updated with data from newly issued patents on roughly a quarterly basis. The PatentsView team is working toward executing updates every even month of the year by reducing delays previously caused by data processing issues and additions. Each update integrates the most recent CPC classification released by the USPTO and applied retrospectively to all US patents dating back to 1976. The USPC classification is no longer assigned to utility patents after May 2016. The NBER classification after 2006 is reproduced based on the current USPC classification until May 2016. The WIPO technology fields are based on the current CPC classification and the IPC to CPC concordance. The inventor, assignee, lawyer and location disambiguation algorithms are re-run on the entire database each time the data update process is complete.

"

That being said... I am confused though because it says "every month of the year", but on the data download site it says that it was last updated in December of last year?...

RE: DATA UPDATES

Thanks for reaching out!


1) The data is updated every quarter - next updates should get pushed to production in June, September, and November.


2) The computed data is re-run for every update. It's a global update - this means that we cannot guarantee that the disambiguated IDs from update to update will remain stable.


3) The processing of an update takes about 4-6 weeks (as of March 2018) to push an update. The most current data (as of Dec 26) was recently posted to the website in mid-Feb.


4) There will be a short delay in the next scheduled post because we are pushing to production an updated disambiguation algorithm which should be reflected in the next update - planned to be posted in June 2018 to include data up through the end of April 2018.
