New product research and development, but I don’t have the production capacity. Ask what should be done. I mainly want to apply for a patent for a new product

Applying for a patent has nothing to do with whether you have production capacity. As long as a new product is developed or you have a clear idea, you can apply for a patent first and then transfer the patent on a professional patent transfer or licensing platform. Find a suitable manufacturer to produce it or simply authorize it to produce it and collect the patent license fee.

So, having no production capacity does not affect the application for a patent.
