The premise of applying for a patent is to meet the "three characteristics":

Inventions and utility models granted patent rights should be novel, creative and practical.

Novelty means that the invention or utility model does not belong to the prior art; Before the filing date, no unit or individual filed an application for the same invention or utility model with the administrative department for patent in the State Council, and it was recorded in the patent application documents published or announced after the filing date.

If the paper is published first, the patent will have no novelty, and then it will be meaningless to apply for a patent.
