After the patent is submitted, the production or sale of the product will not affect the authorization of the patent.
However, it should be noted that after the products produced by ourselves are put on the market, another factory will copy the products, and then the authorization letter has not been approved, so I am afraid I can't complain.
If you are cautious, you can wait until you receive the authorization notice from the patent office, that is, the patent office agrees to authorize, and you can get the patent certificate within 2 months after the authorization registration.
In addition, production can be carried out in secret, and after the patent is determined, it can be promoted and sold.
