After applying for an invention patent, how soon can we start production and sales?

From the date of filing to the date of publication (18 months), the patent law does not provide protection; From the date of publication to the date of authorization, the patent law provides temporary protection. At this time, you can ask the other party to pay the fee, but the other party may not pay the fee, and you can sue after authorization.

If you want products to enter the market as soon as possible, you should ask for patent disclosure in advance when you apply for a patent, so that you can get temporary protection in advance.

If it is required to be published in advance, it can be made after the application date, because the time between the application date and the publication date is very short.
