# Affiliation patents

> Paginated list of the patents associated with an affiliation.

## Path parameters

**affiliation\_type** `string` *required*

Affiliation type: `institution`, `faculty`, `department` or `group`.

**affiliation\_id** `string` *required*

Affiliation identifier.

## 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`, where the direction is `asc` or
`desc`. Available fields: `citations`, `alphabetical` (by title) and
`year` (publication 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]
>
> If you don't send `max`, `page` or `sort`, `max=10`, `page=1` and
> `sort=citations_desc` apply. If you send `max` and `page` without `sort`,
> `sort=citations_desc` applies.
