# Author patents

> Paginated list of an author's patents.

## Path parameters

**person\_id** `string` *required*

Author identifier. Example: `0000000001`.

## Query parameters

**max** `integer` (default: 10)

Results per page (1 to 250).

**page** `integer` (default: 1)

Page number (minimum 1).

**sort** `string` (default: citations\_desc)

Ascending or descending sort criterion, for example `citations_desc`,
`products_asc` or `alphabetical_desc`.

**sort** `string` (default: citations\_desc)

Sort with the format `field_direction`. Available fields:
`citations`, `alphabetical` and `year`. Example: `year_desc`.

**view** `string` (default: full)

Level of detail of the response. `full` returns every field. `summary`
returns only the entity's main fields and, for products, patents and
projects, cuts the author list to 10. Any other value returns `400`.

> [!NOTE]
>
> The response structure is identical to that of [Affiliation patents](https://help.impactu.colav.co/en/api-reference/affiliation/get-research-patents.md).
