I have A patent application to prepare, and thought I could do it myself. What is the proper way to draw patent drawings? For a provisonal, its my understanding they do not have to be formal with numbers. Does that mean do not include numbers referenced to discriptions. Would it be best to number them for a provisonal anyway if you want to be close to a non provisional down the road?
Your description is correct. You don’t need to add numbers, although it is prefered. Generally you just pointed out one aspect of the reason we don’t recommend filling a provisional non-full application. Saving at this stage, usually cost you much more down the road. Beside the fact that you need to file a new full application within a year, some patent offices (i.e. Japan) won’t accept a national phase application , if it is different from the priority application. We think it is always better to get a professional to draft your patent application, that way the numbers on the drawings will follow the right rules.
