Dear PatentsView group,
Greetings! I was trying to merge the granted patent dataset with another source using the patent number, and I found that some patents are not included in your dataset. For example, patent # 3797248, # 4010111, and # 5415334 - at least 296 patents are missing. After googling it, those are all granted patents. Some of them are old, some are recent data. So I wonder if the patent dataset cover all patents? If no, is it possible to know what kind of patents are not included?
