Claims and description text are included on request (`include_text`). PDF downloads are behind a reCAPTCHA and are not provided. - [Search patents](https://firecrawl.dev/alexandria/agents/providers/brevets-patents-ic-gc-ca/intellectual-property/search_patents): Search the Canadian Patents Database. Free-text keyword search by default; set `field` to restrict the query to one bibliographic field (title, abstract, claims, inventor, applicant, current-owner, ipc, pct-number, ...), or give a raw CPD query expression such as `title:(solar panel) AND (issue-date:[2020-01-01 TO 2025-12-31])` with `search_type` advanced or boolean. Returns one page of ranked hits (patent number, title, relevance score, summary URL) with the total count and a `next_cursor` for the following page. The site displays at most 5,000 hits per query (`display_limit_exceeded`); narrow broad queries with a date range. ## 1. Choose this provider when Canadian Intellectual Property Office patent database: keyword, fielded and date-range search over Canadian patents and applications, and the full bibliographic summary of one patent (titles, status, IPC, parties, dates, PCT and priority data, abstracts, claims and description text, event and fee history, owners on record, document list). ## 2. Minimal request Call `POST https://api.firecrawl.dev/v2/scrape` with `{ alexandria: { provider, capability, options } }`. For a batch, send `{ alexandria: [...] }` with up to 10 calls. ```json { "provider": "brevets-patents-ic-gc-ca", "capability": "intellectual-property/get_patent", "options": { "patent_number": "2553707" } } ``` ## 3. Add provider options Use only the options needed for the task: - `include_text` (boolean): Also return the full claims and description text (can be tens of kilobytes). Example: `false` - `language` (string): Interface language of the summary page (labels such as status, event descriptions and fee types). Titles and abstracts are always returned in both languages when the record has them. Example: `en` - `patent_number` (string): CA patent or application number, digits only or prefixed with `CA` (e.g. `2553707`, `CA 3110539`). Example: `` - `url` (string): A CPD patent page URL (`.../opic-cipo/cpd/eng/patent//summary.html` or the French `.../fra/brevet//sommaire.html`) instead of `patent_number`. Example: `.../opic-cipo/cpd/eng/patent//summary.html` ## 4.

capability contract is generated from the same normalized Alexandria API reference exposed in the API spec. ### Get patent - Capability: `intellectual-property/get_patent` - Description: The full public record of one Canadian patent or application from its CPD summary page: kind (patent or application), English and French titles, status, IPC codes, inventors, owners, applicants and agents, filing/issue/publication/OPI/examination dates, licence and dedication flags, PCT and priority data, English and French abstracts, representative drawing URL, administrative event history, fee history, current and past owners on record, and the list of viewable documents. Claims and description text are included on request (`include_text`). PDF downloads are behind a reCAPTCHA and are not provided. - Instructions: You have a CA patent or application number (from search_patents or a CPD URL) and need its bibliographic data, status, abstract, history or document list. - Cost: 5 credits per call - Capability file: [Get patent](https://firecrawl.dev/alexandria/agents/providers/brevets-patents-ic-gc-ca/intellectual-property/get_patent) Accepted options: - `include_text` (boolean): Also return the full claims and description text (can be tens of kilobytes). Example: `false` - `language` (string): Interface language of the summary page (labels such as status, event descriptions and fee types). Titles and abstracts are always returned in both languages when the record has them. Example: `en` - `patent_number` (string): CA patent or application number, digits only or prefixed with `CA` (e.g. `2553707`, `CA 3110539`). Example: `` - `url` (string): A CPD patent page URL (`.../opic-cipo/cpd/eng/patent//summary.html` or the French `.../fra/brevet//sommaire.html`) instead of `patent_number`. Example: `.../opic-cipo/cpd/eng/patent//summary.html` Response schema example: ```json { "abstract_en": "A negative electrode of a lithium secondary battery having a mixture layer containing graphite particles and an organic binder on a current collector, wherein the diffraction intensity ratio (002)/(110) of the mixture layer measured by X-ray diffraction is not higher than 500, and a lithium secondary battery having that negative electrode and a positive electrode containing a lithium compound. Since the quick charge/discharge characteristics and the cycle characteristics do not deteriorate significantly when the negative electrode density of the lithium secondary battery is increased, a high- capacity lithium secondary battery having an enhanced energy density per volume of secondary battery can be provided.", "abstract_fr": "La présente invention a trait à une électrode négative pour un accumulateur au lithium comportant une couche de mélange contenant des particules de graphite et un liant organique sur un collecteur de courant, dans laquelle le rapport d'intensité de diffraction (002)/(110) de la couche de mélange mesurée par diffraction de rayons X est égale ou inférieure à 500, et un accumulateur au lithium comportant cette électrode négative et une électrode positive contenant un composé de lithium. Etant donné que les caractéristiques de charge/décharge rapide et les caractéristiques de cycle ne se détériorent pas de manière significative lors de l'accroissement de la densité d'électrode négative de l'accumulateur au lithium, il est possible d'obtenir un accumulateur au lithium haute capacité présentant une densité d'énergie améliorée par volume d'un accumulateur au lithium.",

`intellectual-property/search_patents` - Description: Search the Canadian Patents Database. Free-text keyword search by default; set `field` to restrict the query to one bibliographic field (title, abstract, claims, inventor, applicant, current-owner, ipc, pct-number, ...), or give a raw CPD query expression such as `title:(solar panel) AND (issue-date:[2020-01-01 TO 2025-12-31])` with `search_type` advanced or boolean. Returns one page of ranked hits (patent number, title, relevance score, summary URL) with the total count and a `next_cursor` for the following page. The site displays at most 5,000 hits per query (`display_limit_exceeded`); narrow broad queries with a date range. - Instructions: Start here to find patent numbers by keyword, title, inventor, applicant or owner name, IPC class, PCT or international publication number, or a date range; then call get_patent with a returned patent_number. - Cost: 5 credits per call - Capability file: [Search patents](https://firecrawl.dev/alexandria/agents/providers/brevets-patents-ic-gc-ca/intellectual-property/search_patents) Accepted options: - `cursor` (string): `next_cursor` from the previous page (the zero-based offset of the next hit). Keep every other input identical. Pattern: ^[0-9]{1,5}$. Example: `next_cursor` - `date_type` (string): Which date the `from_date`/`to_date` range applies to. Requires both dates. Example: `issue-date` - `field` (string): Restrict `query` to one bibliographic field (the CPD advanced-search field list). `intl-number` is the WO international publication number, `pct-number` the PCT filing number. Example: `title` - `from_date` (string): Inclusive range start, YYYY-MM-DD. Requires `date_type` and `to_date`. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `date_type` - `language` (string): Interface language of the results (English or French titles and summary URLs). The query syntax is the same in both. Example: `en` - `page_size` (number): Hits per page (the site serves 10, 25, 50 and 100; any value up to 100 is accepted). Example: `10` - `query` (string, required): Search words, or a raw CPD query expression (`field:(words)`, AND/OR/NOT, `date-field:[YYYY-MM-DD TO YYYY-MM-DD]`). Combined with `field`, only plain words belong here. Example: `field:(words)` - `search_type` (string): CPD search mode. Default: `basic` for plain words, `advanced` as soon as `field` or a date range is given. Pass `advanced` or `boolean` yourself when `query` is already a fielded expression. Example: `basic` - `to_date` (string): Inclusive range end, YYYY-MM-DD. Requires `date_type` and `from_date`. Pattern: ^[0-9]{4}-[0-9]{2}-[0-9]{2}$. Example: `date_type` Response schema example: ```json { "display_limit_exceeded": false, "language": "en", "next_cursor": "10", "observed_at_ms": 1790124190526, "offset": 0, "page_size": 10, "query": "inventor:(Bombardier)", "records_displayable": 59, "records_total": 59, "results": [ { "patent_number": "940388", "rank": 1, "score_percent": 100, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/940388/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "HULL CONSTRUCTION FOR WATERCRAFT" }, { "patent_number": "2128134", "rank": 2, "score_percent": 94, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2128134/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "MOTORIZED WHEELED EQUIPMENT HAVING AN HYDRAULICALLY STABILIZED FRAME" }, { "patent_number": "948574", "rank": 3, "score_percent": 91, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/948574/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "FUEL TANK AIR VENT LINE" }, { "patent_number": "975658", "rank": 4, "score_percent": 88, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/975658/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "STOP DEVICE FOR SNOWMOBILE STEERING MECHANISM" }, { "patent_number": "2812094", "rank": 5, "score_percent": 88, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2812094/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "IDROBIK" }, { "patent_number": "2810323", "rank": 6, "score_percent": 87, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2810323/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "ELECTROLLER" }, { "patent_number": "853505", "rank": 7, "score_percent": 87, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/853505/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "BRAKE SYSTEM" }, { "patent_number": "1043390", "rank": 8, "score_percent": 87, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/1043390/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "WINDSHIELD MOUNTING" }, { "patent_number": "921521", "rank": 9, "score_percent": 87, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/921521/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "WEAR BLADE FOR SNOWMOBILE SKID SUSPENSION" }, { "patent_number": "918200", "rank": 10, "score_percent": 87, "source_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/918200/summary.html?query=inventor%3A%28Bombardier%29&type=advanced_search", "title": "VARIABLE SPEED TRANSMISSION SYSTEM AND BRAKING MEANS" } ], "results_url": "https://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/search/results.html?query=inventor%3A%28Bombardier%29&start=1&num=10&type=advanced_search&newSearch=1", "search_message": "59 documents out of 2,637,202 matched your query.", "search_type": "advanced_search" } ```
