Scraping or Crawling for research purpose , patent data

I am a Ph.D. student in South Korea.

I have a question regarding the use of data from patents.google.com/patent

I am planning to do a research using the patent data, and thinking of using the data provided by Google patents.

Is it problematic if I crawl or scrape the data provided in patents.google.com/patent/(patent number) ? (e.g. https://patents.google.com/patent/US5432808A/)

  • I will crawl small amount of patent (about 200 patents) and will give a proper delay (5-10 seconds per a single patent)

Thanks for your kind response.

Best regards, Suckwon Hong.
