  "query": "lithium battery",
  "databases": "both",
  "maxItems": 10
}

Field	Meaning
`query`	Keywords as in Patent Public Search
`databases`	`both` (default), `grants`, or `applications`
`maxItems`	Cap 1–100

Output

Each row:

patentNumber — numeric id from the index
title, inventors, datePublished
documentType — USPAT or US-PGPUB
kind — grant or application
pageCount, detailUrl (PPUBS deep link)

This search index does not return assignees, abstracts, or claims. Use a detail/PDF workflow or Google Patents Actors if you need those fields.

Notes

Public patent bibliographic data; not legal advice.
Respect USPTO rate limits — keep maxItems modest for schedules.
Inventor names are public patent-record data.
