Can I issue a patent after publishing an article?

If you apply for an invention patent: If the patent you want to apply for is exactly the same as the article, it is recommended not to apply for a patent. The examiner will find out and will be rejected because of novelty. If you can change your technical scheme when applying for a patent, you can apply, but you should pay attention to highlighting the difference between a patent and an article and emphasizing the good effect brought by the difference. If you don't do this, you may be rejected because of your creativity. If you apply for a utility model patent: you can apply, but in general, you will be authorized, but the power after authorization is unstable, that is to say, others can use your article to invalidate your utility model patent, and you will get nothing for nothing. . . . . It feels like you're going to college. Haha
