Patent Crawler

Patent Crawler is a python program to crawl patent information from Google Patent with given keywords.

How It Works?

Google set very low rate-limit on search pages and block any activity wich detect them as scraping. But don't have such policy on each patent page. So at first I download list of patent which include few information include URL, then go to URLs and scrap them. I tried to wrote these programs in user friendly way. So running program will guide you to scrap what ever you want.

Usage

• Clone the repo
• Create a virtual environment and activate it. How
  • pip install -r requirements.txt
• Download gecko driver for firefox from here and place it into code path.
• Now it's time to download gp-search.csv, csv which contain all search result for your keyword. Search_Url_Finder.py guide you step by step to download this csv Or you can do it manualy by go to Google Patent.
  • python Search_Url_Finder.py
• Rename downloaded csv file to gp-search.csv and place it into code path.
• Now run Patent_Crawler.py. It will scrap information of all patents in gp-search.csv and save them to patents_data.csv.
  • python Patent_Crawler.py

Notes

• Patent_Crawler extract this information from patents page (Google Patents) and store them into datafram:

  • ID
  • Title
  • Abstract
  • Description
  • Claims
  • Inventors
  • Patent Office
  • Publication Date
  • URL

• Patent_Crawler have capability to resume from last run. So don't worry if something unwanted happend (i.e Power outage!)

  • Patent_Crawler save data on hard drive after scrap every 5 patents. This can slow down proccess when data became very larg (when we have larg number of patents), So it's better to set this 15 or 30 for better speed.

• Google will block IP if number of requests exceed specific number in each hour (or overal, I don't know it). So I set some sleep in code. You can reduce time of sleep but it increase probability of getting banned!

• Two files will create in the code directory :

  • patents_data.csv --> Contain all information scraped from patents pages
  • not_scrap_pickle --> Contain all pantents from gp-search.csv which haven't be scrapped
