The process of creating or drawing a patent’s drawing is different from the way it was being done during school days. This difference is brought about by the basic rules which need to be followed religiously. Your patent application can be rejected if you fail to follow the set rules. The following are the golden rules followed when drawing utility patent drawings or design patent drawings. They have been put forth by the various patent offices such as USPTO.
Showing all the features clearly
Every feature of an invention must be demonstrated clearly in the paper when you are showing a process, design or a device. Accuracy is also important when showing the different features in the drawing. A patent illustrator will demand every feature to be shown accurately and clearly. This means that the person examining your patent should understand all the features without having to stress his or her eyebrows. For instance, if you are drawing a mobile phone, you are required to show all its features. This will give a clear understanding of your invention.
You avoid presenting a drawing which has some, over writings, strike-thoughts, and alterations. Such a drawing can increase the risk if the rejection of your patent. Even if this is not documented in writing, your patent drawing or illustration should be clean and neat. You should, therefore, present a drawing which is clear ad error free.
This is another important criterion which is not documented, but it should be followed during the entire drawing process. This will involve having the correct spacing between lines and words. Proper spacing will help in making the resulting text visually readable.
Using the metric system
Any sizing information and dimension presented in your patent disclosure should be in the metric system. You can use centimeters or meters. The use of English Engineering Units is not forbidden but most people using the metric system. This rule should be followed as well.
The size of your sheet is also important when making a patent drawing. Most of the patent offices are specific when it comes to the size of the sheet. They will allow you to use a sheet which is 21 cm 29.7 cm (A4). This is the sheet which is used by most of the American people.
Any reading prepared should be legible and visually appealing. A good drawing should be devoid of holes, creases, and folds.
The process of preparing and presenting a patent drawing will require you to have adequate knowledge and artistic approach. You can hire an experienced draft-person to help in developing your drawing.
