Second, search for patents on patent websites (such as official website of the Patent Office). Enter the company name in the "Applicant" box to start the search, and you can get a list of patents applied in the name of the company. The total number of items in the list is the number of patent applications.
Third, check the number of patents that have been authorized in the list (that is, remove those items that are still under review but have not been authorized). Please note that the patent application can only be obtained after it has passed the examination.
