How to apply for a patent
Thread Content
Experts, may I ask how to apply for invention patents and utility model patents, and how to prepare patent specifications?
In simple terms, it means finding a patent specification that has already been authorized and is similar to the type you want to apply for (which can be downloaded for free from the official website), and then writing in a similar style； For some major patents, it is possible to contact some patent agencies. Utility models are relatively simpler and generally do not undergo substantive examination ； Invention patents require a substantive examination, which can take one or two years or even longer.
One has to write first for those who know each other, in order to understand the process and format
Every city has a patent office; you can find them to handle the process, as they have the necessary forms
