This is a PCT (Patent Cooperation Treaty) application. As such, it is never granted. The PCT system allows one application to stand for 140+ applications in as many locations. Only those actual patent offices can grant a patent. In any case, even if you pulled up the publication of a US application that had subsequently resulted in an issued patent, that publication would still not be labeled as granted. The grant results in a new publication with a patent number rather than a publication number but the original application publication remains unchanged.

In general a patent application may not have resulted in a patent after nine years because it was rejected and the rejection was not responded to.

  • so does the PCT application gets granted only after the 140 countries have issued accompanying grants for it?

    No, a PCT application cannot be granted as is. For a patent to issue from a PCT application, the applicant must initiate a national stage application in a PCT signatory country within the appropriate time frame and convince that country to grant the patent. Each country decides to grant or not individually. Jul 8, 2014 at 22:50

To search the current status of a PCT application, based on the publication number, start at http://patentscope.wipo.int/ Type in the publication number without the final A1. Click on the publication number to view the application information. Move across the header to NATIONAL PHASE and click. Look down the list to see if any national stage applications have been filed, and if any patents have issued. This application entered the national stage at the European Patent Office, but was withdrawn and never issued, and in India. No Indian patent has yet issued.

  • After searching I did not see a "NATIONAL PHASE" listed (ex: US20160037217) however it did say "publication kind A1" perhaps that's enough?

  • Most national phase deadlines are 30 or 31 months from the priority date. If there are no national phase deadlines after 42 months, then I don't see how there could be any, except possibly a US matter under some circumstances. May 30, 2017 at 18:15
  • If the "national phase" button is grey, does it mean there has not been any national filing? Jul 23, 2021 at 19:01

It would say GRANTED vs Application.

    But wondering why not granted even after 9 years?

  • There's a lot of reasons why a patent doesn't say GRANT. There could have been too much prior art, or the applicant couldn't afford to finish the process, and so forth. The bottom line unless it says GRANT it's not approved by the patent office. If this were a brand new patent, I would consider it patent pending indeed, but this one is obviously dated. Keep in mind, that another application for a patent could have been submitted based on this one though.

    @AronStein, He is asking why isn't it listed as "rejected". Why is it still listed as "Application" after a whole decade?

  • The A1 at the end of the publication number shows that this is the first publication of this application. This is never changed. If the PCT application published again, there would be an A2, etc. at the end. Jul 8, 2014 at 22:52

On the Google Patent page, on the right hand side you can see "Also published as."

This shows what other forms of this application have been published. This case has been published in the European Patent Office, as an A1, meaning pending application. That means it has not been filed outside the European Patent Office, otherwise there would also be a listing for example for Japan, the US, or India.

The classification (A1, B, C, etc.) can be found here: http://www.thomsonfilehistories.com/docs/RESOURCES_Kind%20Codes%20by%20Country.pdf

Generally As are applications, Bs are patents.

So no, this application has not yet issued. In fact, checking on the EPO site, it has been withdrawn: http://worldwide.espacenet.com/publicationDetails/inpadoc?CC=EP&NR=1824719A1&KC=A1&FT=D&ND=4&date=20070829&DB=worldwide.espacenet.com&locale=en_EP

Event date :    2012/11/14
Event code :    18D
Code Expl.:     -   DEEMED TO BE WITHDRAWN
EFFECTIVE DATE :    20120524

So, no patent will issue.


For US patents please visit USPTO PAIR: http://portal.uspto.gov/pair/PublicPair Type in Patent Number and run search
