Canadian patents and patent applications — search by owner or applicant name, or look up one record by number for its status, filing date and issue date.

Tools

• search_cipo_patents(name, role, limit) — search by current owner or applicant name and get back matching patents/applications: number, title, relevance. role is "owner" (current owner of record) or "applicant" (party that filed); these can differ after an assignment.
• get_cipo_patent(number) — one patent/application’s full bibliographic record: English/French title, current status, filing date, issue/grant date (blank until granted), owners, applicants, inventors, IPC classification.

Data sources

• Canadian Intellectual Property Office (CIPO), Canadian Patents Database — every patent application filed in Canada and every patent granted by Canada, Canadian-origin or foreign-origin alike. Live per-request calls against CIPO’s own public search service; nothing is downloaded or mirrored.

Notes

• A patent that has only been filed, not yet granted, has an empty issued_date — that is CIPO’s own data, not a missing field on our side.
• filing_date is whichever CIPO calls the earliest filing event for that record — the domestic filed date for most applications, or the PCT filing date for one that entered Canada via the PCT national phase. Both answer “when was this filed.”
• Numbers are CIPO patent/application numbers, at most 7 digits. A “CA” prefix, spaces or dashes in the input are stripped automatically.
• CIPO’s own CPD has had intermittent data-quality issues since its 2024 “Next Generation Patents” migration (their notice, not ours) — status fields on some records may lag or show as blank even when the application is active. That is upstream, and this pack surfaces whatever CIPO currently reports.
