fetch-ppubs-patents
fetch-ppubs-patents
is a TypeScript/JavaScript library for pulling patents from the USPTO Patent Public Search API.
It has only one dependency: axios.
Usage
Consistent with the Patent Public Search API, there are only three top-level methods:
fp.searchPatents(query)
- returns an object with search details, including an array with basic patent details (guid, title, classifications, etc. but no main text)
- see type for fields on returned object
fp.getPatentByGuid(guid)
- returns an object with full patent details
fp.getPatent(patentNumber)
- a convienence function that returns an object with full patent details for the first search hit on the passed
patentNumber
parameter
- a convienence function that returns an object with full patent details for the first search hit on the passed
For example:
import * as fp from 'fetch-ppubs-patents'
const results = fp.searchPatents("nvidia.as.")
const firstResult = results.patents[0].publicationReferenceDocumentNumber // "11508113"
const patent = fp.getPatent(firstResult)
console.log(patent)
{
guid: 'US-11508113-B2',
publicationReferenceDocumentNumber: '11508113',
compositeId: '1000006700342!US-US-11508113',
publicationReferenceDocumentNumber1: '11508113',
datePublishedKwicHits: null,
datePublished: '2022-11-22T00:00:00Z',
inventionTitle: 'Denoising techniques suitable for recurrent blurs',
type: 'USPAT',
mainClassificationCode: '1/1',
applicantName: [ 'NVIDIA Corporation' ],
assigneeName: [ 'NVIDIA Corporation' ],
/* LOTS OF OTHER STUFF */
}
