The second step is to draw with CAD software, and simply express the objects or other things you want to write with CAD drawings and mark them.
The third step is to write a patent claim. First, we write the patent claim 1. We should make the language concise, concise and accurate, summarize the described object, that is, explain the object, and explain the installation relationship and position relationship between the parts of the object in a certain order.
The fourth step is to write the dependent claims, which are the explanations and limitations of claim 1, and its scope is smaller than that of claim 1.
Step 5: Check the claim, complete the writing of claim 1 and subordinate claims, complete the whole claim document, and finalize it after careful inspection.
