The above website can only find the specific application information of an enterprise. If quoted, the author uses the patent search engines of innojoy and soopat. Only these two can see the number of patent citations.
David can download the patent information of an enterprise as a whole, but if he doesn't remember to log in to the webpage, he needs to log in frequently. Dawei's patent search results interface is shown in the figure below.
Please click to enter a picture description.
The search results page is still good and clear.
Soopat's patent retrieval results interface is as follows:
Overall, the interface is much better. But soopat's file download is more convenient.
These two companies should be able to do background databases, because the authors are engaged in intellectual property rights and have their own databases, so these are only used for search. As for the number and transaction amount of patents purchased by enterprises, this is the secret of enterprises and generally will not be made public. If it is made public, it may be an internal problem of the enterprise.
