May I ask what preparations should be paid attention to before applying for a patent, or what should be paid attention to? There is also a trademark application for registration. When can it be used?

1, physical examination before pregnancy. In today's society, the competition for survival is fierce, and many young couples work at the same time, so they can't spend too much time having children and raising the next generation. A healthy body is the basic guarantee for pregnancy and childbirth. Therefore, you must go to the hospital for physical examination before pregnancy, especially for couples who are going to have children after several years of marriage. They may have had a premarital examination years ago, so it is necessary to have a physical examination before pregnancy. Because after a period of time or a few years, the health status of both husband and wife may change. It is very important to know the physical condition of both husband and wife and consult questions about prenatal and postnatal care. 2, strengthen nutrition before pregnancy, overcome the bad habit of partial eclipse and picky eaters, fully absorb the nutrition of various foods, and maintain a balanced nutrition. Paying attention to nutrition before pregnancy can improve the quality of germ cells. Vitamins and trace elements such as folic acid can be properly supplemented in the first three months of pregnancy, which is beneficial to the development of the fetus. When the woman was diagnosed as pregnant, she had been pregnant for several weeks. If nutrition is strengthened at this time, it can no longer meet the needs of early fetal growth and development. In addition, early pregnant women often have pregnancy reactions, poor appetite and less food intake, so they should be prepared in advance.
