getClaimFromURL: Get a claim from a Google Patents URL

In kamilien1/patentr: A Toolbox for Analyzing Patent Data

Description

Input a valid Google Patents URL of the form given below and then get back a claim from the index of your choosing. If no claim exists or if your index is out of bounds, an empty character string returns.

The function works on strings that begin with the following sequence: https://patents.google.com/patent/. If the string sequence afterwards is invalid, a 404 status returns from the GET command and eventually an empty string returns.

Usage

getClaimFromURL(googleURL, langCode = "en", whichClaim = 1)

Arguments

googleURL	The well-formatted google URL built from createGoogleURL. It is a character value.
langCode	The language code, used check for non-english text.
whichClaim	Default set to 1, a numeric determining which claim to get. Note if claim is out of bounds, the return claim will be a blank character.

Value

A character vector of the claim from each Google URL. If no claim exists, or if the country code is not on the inclusion list, an empty character value is returned for that index.
