Snapshots including patent status, expiry dates, standardized names, and claims summaries?
The ifi-integrated-content is IFI Snapshots are available for the US, EPO, Australia, Canada, Germany, Spain (without claims summaries), France, and Great Britain. Japanese records also have IFI's enhanced content, although currently without standardized names. Availability of the IFI container , and Japan. Chinese Snapshots are available for Premium Plus subscribers only. Availability by country can be viewed in table form on the the ifi-integrated-content page. Note that access will differ based on your subscription level. In general, if you have access to the full text data for a particular country, then you will also have access to the IFI enhanced data for that country.
Do you have PAIR/PEDS data?
PAIR/PEDS data
Do you have PAIR/PEDS data?
PAIR/PEDS data is available through the Legal Status service of our API. This service provides transaction histories from PEDS which, according to the USPTO, may lag behind Public PAIR by a few days. Since this service is currently BETA, request parameters and response formats may change.

We receive some design patents from DocDB DOCDB so there are some records with bibliographic information in the database. However, in general, we do not cover design patents, and full text is not available for these records. A quick way to find what which designs are available in CLAIMS Direct is to query by kind code since all of them share kind code "S". "E" is also used for design reissues. Therefore, you would search on pnkind:(S* OR E*). You can then see the country coverage for designs by faceting your query by patent country (pnctry). For more information about how to use faceting in CDWI, see the Facet page.
...
US provisional patents are only available in CLAIMS Direct if they have been published by the USPTO. Provisional patents are generally not published, so they are rarely available in CLAIMS Direct. When a US provisional patent is transformed to a "normal" patent, then it is published. The new patent will have different publication and application numbers, but the application number of the provisional patent is always included in the priority data of any member of the family. This application number is the one with a P as kind code "P". You can find them by querying ankind:P AND anctry:US. Other countries can may work differently. Some of them publish provisional patents, like such as Australia. Also, the effect of a provisional patent can may be different in different countries.

How long does it take for translations to become available?
Our translations often do not appear concurrently with the newly published documents for a couple of reasons. For many countries, translations arrive through a service separate from the original application or grant. You can see the breadth of those on the CLAIMS Direct Load Sources page.Our typical delivery schedule, including the timing of translations, typical delivery schedule, including the timing of translations, may be found on the Content Updates page. The applications and grants essentially need to be published as soon as they’re ready due to the significance of that publication. As a practical matter, the publication cannot be held back while waiting for translationWe are now providing English translations from Google Translate with the exception of China, which is receiving improved English translations from a separate source. This change has increased the speed with which translations are available. For all countries except China, translations are now provided one day after the availability of the original text. For Chinese records, English translations are available one day after the publication date.
Do you provide citations?
Yes. CLAIMS Direct provides forward and backward citations, including patent and non-patent literature citations. The patent citations may be accessed using our Citation Service. To access this service through an on-site instance, see Leveraging On-Site Citation and Family Functionality. Citations are also searchable in CDWI. Visit the Citations page to see which search fields are available. For more information about the citation data, see technical-data citations.
...
Yes. Simple family IDs, as assigned by DocDBDOCDB, are available through both CDWI and CDWS using the search field fam. Note that IFI IFI CLAIMS assigns a default a default family ID of -1 if we have not received a family ID from DocDBDOCDB. If you see this value, it means either that the record is not available in DocDB DOCDB or we have we have not yet received the DocDB DOCDB record. In the latter case, the family ID will be populated once we receive the DocDB DOCDB record.
Extended families are only available through CDWS. The reason This is that because the extended family can expand literally daily so it must be generated as needed. Instructions on how to access family information through the API can be found on the the Family page.
...
To access family data through an on-site instance, see Leveraging On-Site Citation and Family Functionality.
How can I tell if a patent is still in force or what its current status is?
We get legal status data for EP patents from the EPO's subscription product, INPADOC. It For China, Premium Plus subscribers also receive legal status data from our Chinese data source. This information is available in the the legal-status container of the XML files.
We also provide USPTO PAIR data through the API's Legal Status service service. However, this This service is currently BETA so request parameters and response formats may change.
For countries which contain IFI 's enhanced contentSnapshots, IFI calculates current legal status. This includes anticipated expiration dates, information about regulatory extensions, terminal disclaimers, and more. All of this information can be found in the ifi-patent-status container container in the XML files, which can be retrieved using the text Text service. For more information, see our documentation on the ifi-integrated-content.

Instructions for installing CLAIMS Direct using AWS can be found on the AWS Installation page.
Updates
How often is the data updated?
The CLAIMS Direct update schedule can be seen on the Content Updates page.
How are updates delivered?
With hosted services, you don’t need to worry about updates. It is easy to identify newly updated records via the API. For an on-site server, there is an update process that uses a web service to retrieve data updates that are published sequentially. The server downloads the new data, updates the XML repository, and triggers a SOLR indexing process if you are running that server. There are a variety of load types, but all of this and more is explained in more detail on the Content Update Architecture page.
What tools are involved in the updates?
CLAIMS Direct uses the utilities apgupd and aidxd. See Update Utilities for more information.
For more information about configuring a server to process updates, see the Processing Server page.
How can I tell which records have been updated?
For on-site instances, the modified_load_id indicates the last time a record was modified and therefore can be used to track updates. This topic is discussed in more detail in the blog post Sorting Through Data Warehouse Updates.
In the XML, there are two ways to tell if a document has been updated:
@statusattribute on thepatent-documentelement@file-reference-idattribute on thepatent-documentelement
If you want to see at a glance whether a document has been updated, use the @status attribute. If you are persisting the data, you should be storing the file-reference-id which can then be used to flag or recognize updates.
For example, this sample record has been updated a few times since publication:
...
You can see that the file-reference-id of an update will have a larger integer than the original delivered value.
Are updates received only for active patents or is it possible to receive an update for any patent?
Most updates affect patents that haven't expired yet or have expired recently, but there are some exceptions. For example, if there is a change in a CPC class that affects records related to a specific class code, then all records with that class code would be updated, whether they are expired or not.
Using CLAIMS Direct
What web services are available from CLAIMS Direct?
The CLAIMS Direct web services provide a comprehensive API that allows for search, XML data retrieval, reporting, specialized services for family and citation lookups, and more. For a full listing and description of the services available, see CLAIMS Direct Web Services.
How can I access the full text?
The Text service is used to retrieve XML data from the CLAIMS Direct Data Warehouse.
To access the full text through SQL, use the following command:
| Code Block |
|---|
SELECT xml.f_patent_document( xml.f_ucid2id(‘US-5551212-A’), null ); |
The full text can also be viewed using CDWI (see Viewing the XML Record).
How can I access patent images?
Attachments are housed on a specific attachment server. You may retrieve them through the Attachments service using our API.
To get PDFs, you can make this call with just the ucid:
...
wget -O- \--header 'x-user:x'\--header 'x-password:y'\'http://cdws21.ificlaims.com/attachment/pdf?ucid=US-20160000001-A1'
To get the first drawing (the image that normally appears with the abstract), make this abimage call:
...
wget -O- \--header 'x-user:x'\--header 'x-password:y'\'http://cdws21.ificlaims.com/attachment/abimage?ucid=US-20160000001-A1'
Note that not all documents have PDFs or abstract images, so your application should check for errors.
To get all of the attachments, you can request the full list of available attachments:
...
How do you calculate the IFI standardized form of the current assignee?
IFI curates the current assignee only for those countries for which Snapshots are available. To calculate current assignee, we use legal event data along with other sources of information. For the US and AU, we receive additional data from the patent offices, which can be found in the assignment history section of the XML. We also do some of our own rules-based work: to identify "individual" (e.g., inventor matches assignee), to standardize the names (e.g., “co” vs “company”), and to create the probable assignee on an application where one isn't present. Our editorial team also creates relationships between names, which are then used in the calculation of the ifi-name-current. For example, when Facebook became Meta Platforms, the change was quickly identified by our editors and the ifi-name-current field was updated to reflect the new name.
Do you make any changes to the data provided in the documents?
No, we do not correct or alter the data we receive from our providers except to normalize data from multiple sources into a consolidated and coherent output format and XML structure. We do report known errors to patent authorities but we do not make changes to the data unless we receive corrected records from our providers. The one exception is the IFI Snapshot data, which we calculate. IFI’s patent status and expiration indicatorsshould not be considered authoritative. An attorney or the relevant patent office should be consulted for an authoritative expiration and status determination.
What does a publication or application date of 10101 or 19000101 mean?
If no date is present in the data we receive from our providers and a document-id element exists, a default value of 00010101 (which may appear as 10101) or 19000101 is inserted. This is done because a date value is required for our processing and to facilitate Solr searching. The 00010101 date is available in Solr responses only and is not present in the XML.

For example, this sample record has been updated a few times since publication:
| file-reference-id | load-source | Description |
|---|---|---|
| 303392 | IFI-Cont | ifi-integrated-content update |
| 303372 | DOCDB | DOCDB update |
| 302363 | USREAS | Reassignment update |
| 302181 | US | Initial load |
You can see that the file-reference-id of an update will have a larger integer than the original delivered value.
How can I tell if my on-site instance is in sync with CLAIMS Direct?
Run the following query on your on-site instance:
| Code Block | ||
|---|---|---|
| ||
SELECT max(modified_load_id) FROM xml.t_patent_document_values; |
Compare the results with the Last loadid shown on the cdwi.ificlaims.com home page.
The results do not need to be an exact match. Anything within approximately 100 load-ids is considered to be in-sync.
Another method is to query the System API and compare the completed_stamp member of the response.
Example:
| Code Block | ||
|---|---|---|
| ||
wget -O- \ --header 'x-user:x' |
...
\ |
...
--header 'x-password:y' |
...

For attachments, you will see a list of available attachments which you can click to open. For biological and chemical patents, there are sometimes .MOL (molecule) and .SEQ (genetic sequence) files.
We also offer a Bulk Attachment service which provides access to complete copies of recently published attachments packaged in a convenient archive.
Some images appear to be missing from CLAIMS Direct. Is there a way to access them?
Japanese records frequently contain multi-page TIFFs. Multi-page TIFFs are indicated when multiple id attributes point to the same file. Many TIFF readers do not read any image data beyond the first IFD (image file directory). Therefore, you may see only the first page.
For example, 2007280735.tif is a multi-page TIFF containing the front page (000001), the abstract drawing (000002), and the drawing sheets (000003-000012) referenced in the drawings section of the XML:
| Code Block | ||
|---|---|---|
| ||
$ tiffinfo 2007280735.tif |grep ImageDescription
ImageDescription: 000001 # front page
ImageDescription: 000002 # abstract drawing
ImageDescription: 000003 # drawing sheets
ImageDescription: 000004
ImageDescription: 000005
ImageDescription: 000006

ImageDescription: 000008
ImageDescription: 000009
ImageDescription: 000010
ImageDescription: 000011
ImageDescription: 000012 |
The XML for this image shows that the file attributes point to the same physical file (2007280735.tif):
| Code Block | ||
|---|---|---|
| ||
<img id="000003" he="101" wi="75" file="2007280735.tif" img-format="tif" img-content="drawing"/>

Are there limits on the API services?
...
Are there limits on the API services?
IFI CLAIMS introduced shared-service quotas beginning in the third quarter of 2019. Rate limits for shared services vary based on your subscription and service levels although the standard rate limit for most shared services ranges from 60-240 request units per window per client login, where window can range from 1 minute to 1 day. You can read more about these quotas here. In addition, there are some limits applied to the individual services. All of the API services which take multiple ucids as parameters have a limit of 100 documents per batch. That number seems to provide provides a good balance between time to prepare the extract and time to push it across the network. The Citation, Family, and Attachments services can tolerate more. We do not have an upper limit for those, but do suggest that you try to hold the maximum to about 500. The limit for Reporting is to push it across the network. The Search and Reporting services are limited to returning 30K documents per batch because deep paging can produce odd resultsplace undue stress on the system.
Is there any time when CLAIMS Direct's services are not available?
...
The CLAIMS Direct index is created and maintained using Apache SOLR Solr (http://lucene.apache.org/solr/) and hence, based on a schema definition, all of the functionality provided by SOLR Solr is available through CLAIMS Direct, including the entire Apache Lucene query language, result set sorting, facet searching, grouping etc. For more information and examples, see the SOLR Solr Searching Guide.
The basic search syntax used in CLAIMS Direct is SOLR Solr field name:value. For example:

For instructions on how to search using the CLAIMS Direct Web Interface (CDWI), see the CDWI guideGuide.
What fields are available for searching?
Fields available for searching in CLAIMS Direct, along with tips and examples, can be seen in the SOLR Solr Search Fields section section. Note that tThe CLAIMS Direct SOLR Solr index does not store all text. This means that although the entire index is searchable, only certain fields are available for inclusion in a result set. Retrievable fields are marked as "stored" in the SOLR Solr Search Fields tables and a quick reference list is available in the Quick Guide to Stored Solr Fields. You can also find them in the schema where @stored="true", or use the the schema method of the Search service to inspect field attributes.
...
There are several ways to search for a particular patent number in CLAIMS Direct. You would use the Use the an field to search for an application number, and pn to search for a patent number. You may also search for a ucid, which is a unique document identifier comprised of the country, document number, and kind code, e.g., US-96142365-A.
Number formats in CLAIMS Direct are generally provided in DocDBDOCDB-normalized format with a few exceptions, which are:
WO: WIPO's format has changed over the years and you can find 3 formats in DocDBDOCDB. We have standardized WO publication numbers to WO-YYYYNNNNNN. For example, the DocDB DOCDB number WO8002869 becomes WO-1980002869-A1 in CLAIMS Direct.
US applications: The DocDB DOCDB format is YYYYNNNNNN, while the CLAIMS Direct format is US YYYYNNNNNNN.
Patent document numbering is a complex subject, however, so you should review the following pages for more detailed information: application-reference and publication-reference. We also recommend checking the Release Notes for patent number or kind code changes.
If you have a list of numbers to search, you may use the List search option in CDWI, which you can read about here. This option includes a validation feature which will convert converts some patent publication numbers into CLAIMS Direct's standard ucid format.
Before you conduct any searches, we recommended recommend that you familiarize yourself with the searching options available in CLAIMS Direct using the SOLR Solr Searching Guide.
...
l1=class, e.g., 161
l2=class+subclass (as integral number), e.g., 161234
l3=class+subclass with trailing decimal if exists, e.g., 161234 [.xxx] -->
So, for For example, if you wanted to search for everything in CPC class class A61K 9/2893 , the most efficient method would be to search by CPC level 5: cpcl5:A61K00092893

Before you conduct any searches, we recommended recommend that you familiarize yourself with the searching options available in CLAIMS Direct using the SOLR Solr Searching Guide.
How do I search for a particular applicant or assignee?
There are several fields you can use to search for an applicant or assignee. See Associated Parties for a full list of searchable parties. Many of these fields are available in various formats, including the original format as filed by the applicant and the EPO’s standardized format. More information about formats can be found on the Common XML Attributes page.
A particularly helpful field to be aware of is the pa field, which provides a comprehensive search of the applicant, assignee, and reassignee fields. We also offer search fields like asgfull that which allow you to search the name and address fields together, which may help to distinguish entities with the same name in different locations.
For countries which have IFI’s enhanced dataIFI Snapshots, we offer standardized names. As you can see on the IFI Integrated Data pagethe IFI Snapshots page, we provide standardized names for the original and current assignees. Similar to the pa field, there is an ifi_pa field which provides a comprehensive search of the original and current standardized assignees. Additional information about our standardized names can be found on the ifi-integrated-content page.
Before you conduct any searches, we recommended recommend that you familiarize yourself with the searching options available in CLAIMS Direct using the SOLR Solr Searching Guide.
