Patent ST.36 (XML)

Download records of patent applications and granted patents filed with the Canadian Intellectual Property Office. We offer a full historical collection and provide new and updated records weekly.

Note: We only publish patent applications after a confidentiality period. This period is up to 18 months after the earliest filing date of an application.

Format

We provide this data in XML. It follows World Intellectual Property Organization standard ST.36.

Note: On May 5, 2022 , CIPO ended the production of 2 of its patent data products: 1) Administrative Status (XML); and 2) Bibliographic and full text (XML). They've been replaced by our Patent XML ST.36 product, which combines the elements of both formats into a single XML file.

Information included

• Bibliographic data: applicant names, title of invention, critical application processing dates, etc.
• Title and abstract text: a short description of the invention
• Claims: a legal description of the scope and specific attributes of a patent
• Disclosure/description: a full description of the invention

Note: We scan the applications using optical character recognition. They do not represent a legal copy.
