I am doing a research out of curiosity.
Topic: "How many patents does each firm have?"
For this; I wrote "SONY" in the relevant part of the link https://worldwide.espacenet.com/patent/search. The result is "224 423" numbers. However, these are not all patents. Those ending in "B1" means patented. The ones ending with "A1,A2..." are not patented yet, they are being researched, examined etc. means.
"B1" quantity is required to reach the final result. To find the quantity "B1" using Ctrl+F, all 224 423 patents in the list must be opened on the page.
I don't want to press the key manually every time. There has to be a way around this with codes. What can I do? NOTE: I am using Chrome. As an add-on "auto scroll,Chrome Auto Scroll etc." I used it but no results.
