Do new technologies and products need to be patented immediately?

Be sure to apply before the public sale and promotion, otherwise the subsequent application is flawed in novelty, and even if it is granted a patent, it will easily fail.

You don't have to wait for the market to promote it. If it is a key product, it is more appropriate to apply for a patent first. In addition to protection, it is also a propaganda point. And now China implements the first application system, and most countries in the world also apply first. If others apply earlier than you, the follow-up will be more troublesome.
