Whether the manufactured products will infringe others' patents.

1, the purchase contains other people's patents, and there is no infringement. Because the patent right was used up when the product was just sold, you bought it in the market, which is a normal business behavior.

2. The protection scope of patent right lies in the process of manufacturing, selling, using and importing, so it is risky to sell patented products as part of your products without the authorization of the patentee.
