It stands to reason that a patent promotion company, as an intermediary, can help you promote patents.
But now many companies take advantage of the patentee's eagerness to find a buyer, trying to convince you of his role and let him publish an announcement at your expense. The key is whether the cost you pay matches the cost of publishing the announcement, and in which media the announcement is published.
In fact, it is almost impossible for a manufacturer who really wants to buy a patent to find a patent through the so-called patent announcement newspaper, because the contents of such newspaper announcements are varied and cannot be searched automatically.
Imagine if you were a manufacturer and wanted to buy a patent in a certain professional category, how would you find it?
Just go to China National Intellectual Property Administration's website and search for all the patents you want. Don't miss any of them. It can be arranged according to different categories (patent type, authorization date, etc.). ), and you can choose which patent is more valuable to obtain. Do you still read newspapers? How many patents can you find in the first issue of the newspaper? Maybe none of them can be found.
It should be clear how to promote patents.
