Khan Academy is a website that provides free educational resources, mainly covering teaching videos and course materials in the fields of mathematics, science and computer programming. Although Khan Academy itself does not provide patent literature search and download services, you can learn about technology and patent information in related fields through the course materials and teaching videos provided on the website of Khan Academy.
If you want to find patent literature, you can consider using a professional patent database or search engine. These databases and search engines usually cover patent literature information on a global scale and can provide detailed patent descriptions, abstracts, technical fields and other information. The use of these resources can be added to the study plan of Khan Academy, so as to better understand the technologies and patents in related fields.
