Release Notes

May 2022: CLAIMS Direct CDWI 2.9.1 released

The following fixes and enhancements are included:

  • A new reporting option csv.datefmt was added to the New Report screen.
  • A bug wherein attachments with identical names were suppressed from grid listing output has been fixed.
  • Updated Privacy and Terms of Use

May 2022: CLAIMS Direct CDWS 3.9.1 released

The following fixes and enhancements are included:

  • A bug that made the endpoint /attachment/update take minutes when no @limit parameter was given has been resolved.
  • system/dwh/loading endpoint is now streams aware. This resolved an issue when a @load_id parameter was from a non-xml stream, the endpoint returned HTTP 204.
  • In an effort to harmonize date output formats in the Reporting API, a new csv.datefmt option is available. Please see Reporting for more details.

May 2022: CLAIMS Direct Client Tools 2.6-3 released

The latest release of the client tools adds further enhancements to streams processing. In addition, package download integrity is maintained by the addition of an MD5 checksum.

April 2021: CLAIMS Direct Client Tools 2.6-1 released

This latest release introduces streams capability. This new feature allows the seamless integration of custom XML content, non-patent data sources and custom data filtering for on-site customers. Additionally, aidxd has a new argument --tolerate which directs aidxd to tolerate all errors and retry. This brings aidxd in line with the current behavior of apgupd. Due to the change of behavior, this argument is optional but future releases may make this the default behavior. If you wish to use it, simply add it to the CD_OTHER_OPTIONS option in /etc/alexandria/aidxd.conf ( CD_OTHER_OPTIONS='--tolerate'  ) and restart the daemon via systemctl.

March 2021: Attachment service enhancements

On March 20, 2021 we are releasing the following enhancements to the Shared Services /attachment endpoint:

  •  @exclude has been added as a parameter to the /attachment/fetchall endpoint. This allows you to exclude specified extensions from the package. See /attachment/fetchall for full details.
  • The attachment/abimage endpoint, which allows you to fetch a front page drawing or figure, has been enhanced to handle image manipulation. See /attachment/abimage for more details.

March 2021: Litigation API released

Global litigation data from MaxVal is now available on the CLAIMS Direct platform as an optional data subscription. Case details, outcomes, party data and more are available from multiple courts. The data is provided in a similar XML style to other CLAIMS Direct content, making it easy to integrate with other patent content. See Litigation to read more about how to access this service.

March 2021: Chinese Snapshots

From March through August, approximately 30 million IFI Snapshots will be added to our Chinese full text documents. This will allow Premium Plus subscribers to access IFI’s standardized names, patent status, expiration dates, and claims summaries for Chinese records. To read more about the IFI Snapshots and how they can help you, see IFI Snapshots Explained.

February 2021: IFI Snapshots

For over 70 years, IFI CLAIMS has created value-added data which provides an overview of a patent document at a particular moment. Our patent status, expiry dates, standardized names, and claims summaries have been relied upon by professionals for decades to provide the key information necessary to evaluate patents quickly and efficiently. We have now come up with a term which we feel captures the essence of this vital information: the IFI Snapshot. To read more about what IFI Snapshots are and how they can help you, see IFI Snapshots Explained.

November 2020: Names API released

The Names API is now available to Premium Plus subscribers. This service allows users to retrieve CLAIMS Direct IFI names and name variations as well as ultimate corporate owners and subsidiaries. More information about how to use this service is available here.

July 2020: Source attribution added

As required by the French Patent and Trademark office (INPI), we have released a patch which adds a source attribution. The patch is available through the following link:

Installation instructions and further details are included in the README file. On-site installations must apply this patch before August 1, 2020.

June 2020: Support for RHEL/CentOS 8

CLAIMS Direct now supports RHEL/CentOS 8. Instructions for new instances have been incorporated into the PostgreSQL Installation Instructions and the repository information is provided in the Software Requirements on our PostgreSQL page.

June 2020: New PostgreSQL schema and tools package

In an effort to further streamline CLAIMS Direct PostgreSQL schema versioning, we are introducing a schema and tools package into the CLAIMS Direct yum repository. The new package will offer the main CLAIMS Direct database schema as well as the supporting users database to support deployment of on-site web services. The package contains the SQL to create the database(s) supporting PostgreSQL versions 9.2 - 10.x, as well as tools to check installation, populate the tables, perform extracts, and more. See PostgreSQL Schema and Tools for more information about the package, including instructions on how to install it.

April 2020: CDWS/CDWI report expirations

Going forward, reports created using the CDWS endpoint /reports and CDWI reporting interface will expire after 6 months and will be automatically removed. We intend to begin the pruning on June 6, 2020. Please download any reports older than 6 months that you wish to keep.

April 2020: Client Tools 2.5.3 release notes


This release contains changes pertaining to how the software is deployed on the system. At the end of 2017, we moved to an RPM-based software distribution by introducing the IFI CLAIMS Direct repository. This release further aligns the installation with distribution standards. The following enhancements are included in v.2.5.3:

  1. An unprivileged service account is created and controls processes and configuration files.
    The new user alexandria will be created on installation or upgrade whose home directory will be /var/lib/alexandria. 
  2. Configuration files are located in the standard system configuration directory.
    All tools included in the Client::Tools package require a valid alexandria.xml file for database and index settings. This file is now located in the standard system configuration directory /etc. In addition, configuration files pertaining to systemd and init.d control are located in the directory /etc/alexandria. 
  3. Log files are located in standard system logging directory ( /var/log/alexandria ). 
    By default, this will be /var/log/alexandria/alexandria.log. 
  4. Data warehouse updating and SOLR indexing daemons are controlled through systemd and init.d. 
    For CentOS 8 and RHEL 7, the service files apgupd.service and aidxd.service will be installed in the systemd service file directory to enable, disable, start and stop the services. For Amazon (amz1), the service files apgupd.init and aidxd.init will be installed in /etc/rc.d/init.d to enable standard chkconfig  and service start, stop, restart and status commands.

Upgrade Paths

  • Upgrading Alexandria-Client-Tools from versions earlier than 2.1.1 (non-repository versions):
    Please contact
  • Upgrading Alexandria-Client-Tools from version 2.1.1 and above (repository-controlled versions):

    yum update perl-Alexandria-Library
    yum update perl-Alexandria-Client-Tools

    Please note there are two new configuration files /etc/alexandria/apgupd.conf  and /etc/alexandria/aidxd.conf which require editing for appropriate user name and password to interact with the CLAIMS Direct primary update server. See Client Tools documentation for details.

January 2020: On-site citation and family functionality

With the deployment of the cumulative patch alexandria-sql-patch-alpa-3636-20191101, on-site CLAIMS Direct installations gained the ability to utilize family and citation functionality in-house. We are now offering a supplemental patch which will allow bulk loading of the tables needed to support these new functions. The new patch also expands the available functionality to make citation and family data easier to access. The supplemental patch is available through the following link: For a full discussion of how to use these new functions, see Leveraging On-Site Citation and Family Functionality.
