Content of the Database

The complete Decisions of the Commissioner of Patents collection comprises approximately 1,250 decisions rendered by the Commissioner of Patents since 1970 on issues raised during the examination of patent applications. This collection is divided into two categories: public and non-public decisions.

Public decisions included in this database are those decisions related to applications that belong to one of the following groups:

a) Applications filed prior to October 1, 1989, which became available to the public through:

  • granting of a patent;
  • an appeal to the Federal Court of Canada; or
  • authorization given by the applicant.

b) Applications filed after October 1, 1989, regardless of whether or not a patent was issued.

Non-public decisions relate to applications filed prior to October 1, 1989, for which a patent was not issued, and for which there was neither a filing of an appeal to the courts nor authorization given by the applicant to make the decision public.

This database provides access to the bilingual public decisions of the Commissioner of Patents. There are a number of public decisions that are not included in this database because they are not available in a bilingual format. These decisions, however, delivered between 1978 and 1985, pertain to applications for which the sole grounds for rejection was obviousness, and therefore they are considered to be of limited use in understanding CIPO's policies related to patent application regulations and procedures. Copies of these public unilingual decisions are available through the Client Service Centre or you may order online.

Once a new decision of the Commissioner of Patents is made available, an applicant has a period of six months to appeal the decision to the Federal Court of Canada. Once this period has expired without n an appeal having been filed, a patent may be issued according to the conditions prescribed by the decision of the Commissioner of Patents in the case of the application being accepted. In the case of a refusal, the application will be abandoned. However, if there is an appeal, the outcome of the application will be according to the decision of the highest Court to have heard the last appeal, whether it is the Federal Court of Canada (Trial Division), the Federal Court of Canada (Appeal Division), or the Supreme Court of Canada.

This database contains decisions of the Commissioner of Patents in text and image format as well as bibliographic data. Searches may be performed using the following criteria: topics, text (in English, in French, or both), decision of the Commissioner of Patents number, application number, patent number, International Patent Classification (IPC), Canadian Patent Classification (CPC) and date (See Search Criteria below). A "hit list" of matching Decisions is returned. Images are not searchable but can be viewed for any particular Decision that has been returned in a hit list.

Currency of Information

Decisions of the Commissioner of Patents will normally be available on this site within one week of being made public.

Decisions of the Commissioner of Patents

Once a patent examiner concludes that the dialogue of reports and replies between the applicant and himself has reached an impasse, a document called a "Final Action" is written. This document describes the position of the applicant, the position of the examiner, and the differences between the two.

It is this document, once transmitted to the Patent Appeal Board (PAB) after the time limit to respond to the Final Action (either by amending the application or arguing the grounds for objections) has passed, that starts the process leading to a Decision of the Commissioner of Patents.

The PAB, an administrative tribunal composed of two to three members, reviews the Final Action and all pertinent evidence. If requested by the applicant, an oral hearing will also be convened. The PAB, after hearing the parties, provides a recommendation to the Commissioner of Patents.

After reviewing the PAB findings, the Commissioner makes a decision, which includes a brief statement describing the reasons for the decision based on the recommendation of the PAB. If the examiner's position is upheld, the applicant will be informed of the reasons and given an opportunity to amend the application to comply with the Patent Act or Patent Rules, if possible. If it is determined that the examiner's rejection was not justified, the application will be returned to the examiner for re-examination. An applicant may appeal a Decision of the Commissioner of Patents to the Federal Court of Canada.

A##A ###/##
e.g. A61K 37/04
A is the section
A61 is the class
A61K is the subclass
A61K 37 is the group
A61K 37/04 is the subgroup
Canadian Patent Classification (CPC)

The CPC is the classification system used by Canada prior to October 1989 to classify inventions. Each application was assigned a main (primary) classification and, sometimes, multiple secondary classifications. The classification has the following format:
