Release Notes

June 2017: Delivering priority-linkage-type codes

Since February this year the attribute list for element priority-claim contains an optional attribute linkage-type, which is related to divisions, additions and continuations among others. For some authorities, this is especially important when we calculate expiry dates.

From now on we are delivering the priority linkage type codes when available.
Example: AU-2017202677-A1

<priority-claim mxw-id="PPC175612506" ucid="AU-2015050665-W" linkage-type="A" load-source="docdb">
  <document-id format="epo">
    <country>AU</country>
    <doc-number>2015050665</doc-number>
    <kind>W</kind>
    <date>20151026</date>
  </document-id>
</priority-claim>

Regarding the backfile, we will reload records for countries where this data affects expiry dates. I this sense, reload of the NL backfile is complete as of load-id 268293.

For more information, see XML content description.

May 2017: BR and TW data loaded

Premium+ subscribers now have access to full text of BR and TW documents as described in the Data coverage table.

We loaded close to 1,2 million records covering TW applications, utility models and granteds and more than 100,000 Brazilian records.

April 2017: Planning a reload of ifi-integrated-content of EP records

We would like to announce an improvement in the way we calculate the patent status for EP Designated States. Our upcoming reload of EP records will incorporate the following changes:

Due to customer requests for a simple live/dead status, we are now offering an In-force/Not-in-force status for Designated States. This will result in a more reliable and easy-to-understand calculation of status, and will make this field more usable for things like queries and reports. The new rules are described in more detail here. Our prior calculation rules can be seen here.
As a result of this reload and the previous reload of bad formatted claims, we will add the Claims Summary information to EP records.
We plan to start reloading EP granted patents on May 22, 2017. This will take a few weeks.

April 2017: CH data available

Premium and Premium+ subscribers now have access to full text of CH applications and granted patents both in the original language and in English translation. We have updated 98,224 records published from 1980 to February of this year.

March 2017: dnum-type added to citations

dnum-type is an attribute added to citations in order to distinguish between publication and application numbers.
In order to avoid a complete reload of patent citations, we only add the dnum-type attribute to cited applications. If no dnum-type attribute is present on the patcit element then the citation is referencing a publication.

As a result, 77,786 records having cited applications have been reloaded. Below you can see one example:

March 2017: We start loading TW data

We started loading the back file of TW data in early March. Premium+ subscribers will have access to this data in the next few weeks. We plan to cover applications, granted patents, and utility models published from 2000.

March 2017: Reload of euro-PCT claims finished

Euro-PCT records reload is now complete. We solved format issues found in the original data, so there are no longer any claims with an empty num attribute in our EP collection.

This reload fixed:

Approximately 520,000 EP records published between 1978 and 2012 with missing claim numbers (e.g. EP-0000252-B1)
Approximately 1 million EP records with format issues in the claims element (e.g. EP-0006849-A1)

Feb 2017: Upcoming reloads

Claims format: In 2016 we fixed some content-format issues in the claims section, which were wrong in the original data sources. For example, JP national data is delivered with all claims squashed into claim 1. Also we get some records without claim numbers. The two big claims reloads that we completed are: 5,763,744 JP original language claims and 1,773,963 WO claims. Total - more than 7.5 million claims fixed.

Euro-PCT records, which have the same issues than the "parent" PCT records, are going to be reloaded to fix the claims issue.
We plan to complete this reload before the end of February 2017.

Citations: DOCDB used to consolidate all citations at the earliest publication, A1 or A2 kind codes. This changed at some point last year and now citations are no longer consolidated. As a result of this change we are going to reload citations for about 14,5 million records in the upcoming weeks.This reload will fix a related issue, a former limit of 99 in the number of citations. This limit doesn't exist any more and after the reload approximately 173,000 records will have more than 99 patent or non-patent citations.
We plan to complete this reload before the end of March 2017.

Apr 2016: Details for Duplicate Citation Fix

This fix affects approximately 1.1 million records from 17 authorities where we have identified duplicate citations records. This reload will eliminate these duplicate records.

We plan to complete this reload between Apr 1-7, 2016.

Mar 2016: Details for WO Reload

We are reloading WO records published between 1978 and 2009 in order to add original parties data including agent and correspondent which is not covered via DOCDB. In addition we will add more complete priority data and improve claims structures.

We plan to complete this load between Mar 7-31, 2016.

The following provides an example of the priority-claims and parties changes.

Feb 2016: Details for US Grants Reload

We will reload the <application-reference> and <publication-reference> containers for approximately 3.6 million US grants. We will be adding entity-status at the publication-reference level as well as original format application-reference information. We will also fill in missing art unit. (see details below).

We plan to complete this load between Feb 22 and Mar 7, 2016.

The reload will include the missing us-art-unit attribute for US grants from 2001-2004. Additionally we will add national application number in its original format. So for example:

US-6500018-B1 before update:

<application-reference mxw-id="PAPP61299422" ucid="US-94451301-A" us-series-code="09" load-source="docdb">
<document-id format="epo">
<country>US</country>
<doc-number>94451301</doc-number>
<kind>A</kind>
<date>20010831</date>
<lang>EN</lang>
</document-id>
</application-reference>

US-6500018-B1 after update:

<application-reference ucid="US-94451301-A" us-series-code="09" us-art-unit="2833">
<document-id mxw-id="PAPP61299422" load-source="docdb" format="epo">
<country>US</country>
<doc-number>94451301</doc-number>
<kind>A</kind>
<date>20010831</date>
<lang>EN</lang>
</document-id>
<document-id mxw-id="PAPP95329224" load-source="patent-office" format="original">
<country>US</country>
<doc-number>09944513</doc-number>
<date>20010831</date>
<lang>EN</lang>
</document-id>
</application-reference>

In the case of entity-status, this will be added to the publication reference.

Example new entity-status attribute in US-7318729-B2:

<publication-reference fvid="75564347" ucid="US-7318729-B2" entity-status="small">
<document-id>
<country>US</country>
<doc-number>7318729</doc-number>
<kind>B2</kind>
<date>20080115</date>
<lang>EN</lang>
</document-id>
</publication-reference>

Feb 2016: Details for JP Reload – rekey corrections

We have identified about 2.5 million JP records that were "re-keyed" to fix their publication numbers. The new records were loaded, however the old records were never marked deleted. These effectively duplicate records will be reloaded and marked deleted between Feb 13-17, 2016.

Main Differences Between CD1.5 and CD2.0

The web service authentication method has changed from httpauth to using the http headers to pass x-user and x-password to the service
With 2.0, JSON response are now wrapped in a response container so in CD1.5 {responseHeader:...} in CD2.0 is {status: success, time:1 ...content:{responseHeader:....}}
New reporting service allows authorized users to produce CSV formatted data sets from lists of patent numbers or search results
