Patent Drawings are not what you’d expect. The first thing that comes to mind for most people are the engineered drawings with the dimensions called out on a large piece of paper. Some of us have grown up with some rudimentary knowledge of plans for a building or a home remodel project whereas every detail is called out, followed with dimensions. Not so for the patent drawing.
The USPTO (United States Patent and Trademark Office) has very specific requirements for patent drawings that are to be submitted. The USPTO requires everything from varying sizes of margins on the same page, to markings on opposite corners of the page, calling for each mark themselves to be a specific size! Fonts, depending on what they’re identifying, are sized specifically to what they’re showing. If you have numbered parts on an assembly, the USPTO require different style lines extending from them, again, depending on if it’s a single part, or an assembly of parts.
So what’s my point? You should submit your drawings for your patent correctly or they’ll be rejected. There are books to explain how to do this, or, I can help you in producing the drawings as well. If you already have a patent agent or attorney, I can make drawings according to what they require.
If you’re just applying for a provisional patent, the requirements are different from that of a utility patent. A provisional patent “holds your place in line” (so to speak) and may never be looked at by a patent agent until you submit a utility patent. A design patent is different from both of these. There’s a plethora of information on-line but this is just a quick overview. I talk about this more on the How to Start an Invention page.
