CA is an abbreviation in this wiki referring to Canada.


The Canadian patent office at the time of early aviation was apparently known as the Canadian Patent Office; the current one is the Canadian Intellectual Property Office. At some early stage the GB patent office handed off to the Canadian one. The Duy paper may explain.[1]

LTA's first impression of pre-1900 Canadian aero patents is (a) that they are scarce compared to GB, US, and FR – one or two filed per year, and (b) that many are filed by inventors outside of Canada. In some cases we can see that the Canadian patent complements a patent filed in the home country; in other cases (e.g. Patent CA-1890-34397) the inventors are foreign but we don't have a record of a home country patent.

Sources of Canadian patents

  • Espacenet. Scans of Canadian patents on espacenet show typescripts, as opposed to the usual, more finished-looking form available from other offices. As a result the same patent in Canada has more pages.
  • Canadian Patent Office Record – claims with selected illustrations, available from 1873.
