1. Look up the patent you want to buy on official website of National Information Bureau, and determine the keywords and IPC classification number. From the description, you can find out the patentee of the patent, the time and place of patent application, and you can contact yourself. I believe that your company has engineers who know this technology very well, but buying patents also requires professionals who know patents, that is, patent agents;
2. Purchase patents through agents. Of course, the agency will charge a certain agency fee. Choosing a responsible agency can save a lot of energy for your company. At the same time, your company needs to verify the legal status of the patent.
3. The price of patent depends on the market value of patent. It is suggested that it is best to buy an invention patent. If you buy a utility model patent, you need to let the patentee issue a utility model evaluation report.
