Product description: administrative status data
From: Canadian Intellectual Property Office
Data for patent administrative status is provided in XML format with individual XML files for each individual patent. The XML file structure is governed by the World Intellectual Property Organization (WIPO) standard ST.36 for patent data.
Record and data content
Records for both patent applications and granted patents are included. Patent data is open to public inspection after a confidentiality period of up to 18 months after the earliest filing date of an application. As a result, patent files consist of either a patent application or a patent that has been issued or granted. Each XML file includes the following types of information regarding the granted patent or patent application:
- Bibliographic data (names and addresses of inventors, assignees and agents, critical dates such as filing, publication & issuing, classification codes, etc.)
- Title and abstract text (a short description of the invention)
- History of administrative status changes
Production schedule: weekly and annually
On a weekly basis, a collection of XML files are produced for all patent applications or granted patents that have been updated or are new. These collections of updated and new files are provided for the current calendar year. This results in 52 weekly collections that range from 1 MB to 5 MB depending on volume of activity. The naming convention for XML files includes the patent number and the extraction date. In addition to the XML files, a "Log" file and "OpStat" file are produced for both new and updated patents. The "Log" file contains a list of all patents extracted and the "OpStat" file provides statistics related to the extraction process.
On an annual basis, a complete refreshed collection of XML files of patent administrative status data is produced. This includes all patents from 1869 to the most recent completed calendar year. Collections are organized by year based publication date. As of 2017, a collection of refreshed patent data consisted of 149 folders of approximately 3.5 GB. The naming convention for XML files includes the patent number and the extraction date.
