Company Search

Post by Boutheina » Mon Mar 27, 2023 11:22 am

Hello,
I thank you for the quality of the search you offer, otherwise, I would like to notify that I have noticed, that the patents recovered from Justia for a search of a competitor name are much more numerous than those obtained from Espacenet, even if the publication years are recent (the results are 17 vs 12), is there any explanation/ solution?
Thank you for your collaboration.
Best regards,

Dear Boutheina,

One possible reason is that an Espacenet result list item is a selected publication representing a patent family, i.e. an Espacenet result list does not show all publications of all patent families - a patent family being basically one invention filed and published by a number of patent offices.

For example: pa = "APPLIED MATERIALS" returns today 16.978 patent families corresponding to a total of 73.459 publications as visible in this screenshot:

Thank you for providing the search results. I have observed that the number of patents retrieved from Justia for a competitor name search is significantly higher compared to the results from Espacenet, even for recent publication years (17 vs 12).
