"Missing" patents on Google Patents

Hello,

My question concerns two distinct types of "missing" patents in Google Patents. 

Consider patent_id == 7642713. If I search for this patent on the PatentsView search engine, and then click "Go to Google Patents" I get a "404" error.  If I go to Google Patents and key in either the patent number or the title of the patent, "Electroluminescence element and a light emitting device using the same," I cannot find the patent. 

That is one type of "missing," and I am curious why it might be missing from Google Patents. 

There is another type of missing. Consider patent_id == 7652371. One also gets a 404 error when linking to Google Patents. However, if you manually search for this patent on Google Patents, it will take you to a similar looking patent application: US5162896A. Quite quickly, you can see where the patent number for PV may be coming from. If you look at the "events" timeline, you will see it is listing events for "Application US7/652,371." According to Google Patents, this patent was never granted. But, PatentsView has it granted in 2010.

The community is probably unable to provide support on the first type of "missing," since it is an issue with Google Patents, not PatentsView, but the second type of missing worries me, in the sense that it seems possible that PatentsView is incorrectly recording a grant. 

Note that I chose relatively new patents (both granted in 2010) so that I could decrease the likelihood of it being an issue of transcribing written documents. 

Many thanks in advance for any help that anyone can provide!

I just want to add a type of missing that the community can probably provide some insight into.

Consider patent number == 8455078. This is in Google Patents (granted in 2013) --- https://patents.google.com/patent/US8455078B2/en?oq=8455078 --- but it is missing in PatentsView. 

 

By the way, the motivation for this question is that I am trying to merge a dataset that is generated from Google Patents to PatentsView data. In the majority cases, I can do this using the patent_id, but there is an imperfect concordance.

Withdrawn patents and missing data

Hello,

For both of the cases in your initial post, the patent in question has been withdrawn.

As a general practice, PatentsView maintains the original data for withdrawn patents while adding the "Withdrawn" marker on the patents table. Many other sources, however, do not present data for withdrawn patents. Unlike expired patents, which are in force for a time and then cease to be in force, withdrawn patents are treated as never having been in force at all.

For legal details on the status of withdrawn patents and the conditions under which a patent might be withdrawn, see the USPTO's Manual of Patent Examining Procedure, Chapter 1300, section 1308. If you encounter a patent ID you suspect might be withdrawn, you can check the USPTO website's list of withdrawn patent numbers (downloadable form also available on the same page), or you can search for that patent on USPTO's Patent Public Search. Withdrawn patents will appear in the advanced search like this:

A screenshot of the Patent Public Search displaying the text "TEXT NOT AVAILABLE. DOCUMENT ID: US 07642713. US CLASS CURRENT: WITHDRAWN"

To briefly address your note regarding patent 7652371 and application US7/652,371, application numbers and patent numbers are not connected, and because they can both have seven digits, unrelated documents may by chance end up with matching ID numbers, but this does not represent a direct relation of content.

Regarding the example in your second post, 8455078, this patent has not been withdrawn and does appear to be a genuine absence in our patent data. Our data team is looking into the source of this gap, and we will update when the relevant data has been restored. 

Best,
PVTeam

Thank you! This was very helpful and makes good sense; I'll be curious to hear about the status of patent 8455078 + patents like it.

patents missing from original XML

Hello,

Our data team has confirmed that patent 8455078 is one of a small number of patents that is known to be missing from the USPTO’s bulk patent data XML files that PatentsView is based on. Unfortunately, we do not currently have a timeline for identifying an alternate data source and incorporating these missing patents. That short list of 305 known missing patents can be viewed here.

Best,
