Is it infringement that my things are similar to other people's patented products? If not, can I apply for a patent? We are all handicrafts. .

Infringement or not depends on the degree of similarity you say. . .

When judging infringement, we don't compare products with products, but compare our own products with other people's patent documents to see if our products contain all the technical features protected by the patent documents of the other party. If it is, then it is really infringement.

You can explain your problem clearly, and I'll help you analyze it when you are free.
