I invented this product. Can I go public without applying for a patent? Because the company has just been established, I can't support it if I wait for the patent to be reproduced. I can invite my classmates to study it specially.
You didn't apply for a patent, so did someone else apply? One disadvantage of not applying for patent listing is that it is impossible to protect rights because it is counterfeited, and another risk is that the patentee of similar products counterclaims infringement. When you say that funds are difficult to support, it is even more necessary to avoid risks.
Of course, after you formally enter the patent examination and approval procedure, you can produce and sell it, as long as you ensure that no one is rushing to register this patent, protect the core technology of the product and prevent leakage.
I hope my answer is helpful to you.
