What should I do if I lose my patent paper?

In the worst case, your invention may be made public, which may affect your patent application or be taken by others to apply for a patent.

But I think the probability is too small, and the probability of being swept away as garbage is very high.

If you are paying attention to it, don't waste time asking questions about it. It is the right way to apply for a patent immediately.
