# Search Google Patents

Returns Google Patents results for a query, with inventor, assignee and key dates. Use it to search prior art or follow a company's patents.

Tool `google.serp.patents` on Google. Contract version 1, released 2026-10-27.

## Example call

Over REST, send the input in the body. Over MCP, pass the same input to `call_tool`.

cURL:

```bash
curl https://api.voxoria.ai/v1/tools/google.serp.patents/calls \
  -H "Authorization: Bearer $VOXORIA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input":{"query":"solid state battery"}}'
```

Python:

```python
import os

import httpx

response = httpx.post(
    "https://api.voxoria.ai/v1/tools/google.serp.patents/calls",
    headers={"Authorization": f"Bearer {os.environ['VOXORIA_API_KEY']}"},
    json={"input": {"query": "solid state battery"}},
    timeout=60,
)
print(response.json())
```

TypeScript:

```ts
const response = await fetch("https://api.voxoria.ai/v1/tools/google.serp.patents/calls", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.VOXORIA_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({"input": {"query": "solid state battery"}}),
});
console.log(await response.json());
```

MCP (`tools/call` params):

```json
{
  "name": "call_tool",
  "arguments": {
    "tool": "google.serp.patents",
    "input": {
      "query": "solid state battery"
    }
  }
}
```

Both return [the full response](/docs/call-response.md): the call's ID, status and cost, with this tool's result in `output`.

## Input

| Input | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `query` | string | Yes |  | The search query. |
| `page` | integer | No | `1` | Page of results. At least 1. |

## Output

A successful call returns these blocks in its `output`. A field not marked required can be `null`.

### results

A list of rows. Always present, possibly empty.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `position` | integer | No | Rank among patent results, starting at 1. |
| `title` | string | Yes |  |
| `url` | string | Yes | Address of the patent's page on Google Patents. |
| `snippet` | string | No |  |
| `publication_number` | string | No | Number the patent office published the document under, such as "US10452978B2". |
| `inventor` | string | No | Name of the inventor as Google shows it. |
| `assignee` | string | No | Name of the owner of the patent as Google shows it. |
| `priority_date` | string | No | Priority date, as an ISO 8601 date. |
| `filing_date` | string | No | Date the application was filed, as an ISO 8601 date. |
| `grant_date` | string | No | Date the patent was granted, as an ISO 8601 date. Absent when it has not been granted. |
| `publication_date` | string | No | Date this document was published, as an ISO 8601 date. |
| `language` | string | No | Language code of the text returned, such as "en". |
| `image_url` | string | No | Address of the thumbnail of the patent's first figure. |
| `figure_urls` | array of string | No | Address of each figure of the patent at full size, in the patent's order. |
| `pdf_url` | string | No | Address of the patent document as a PDF. |

## Example output

The `output` of a real call, each list cut to 3 items.
