Creating a drawing for a patent is very different from what we did in our school days. Unlike drawing at school, here we have certain rules and we must follow these rules religiously, otherwise it may cost a rejection on the patent application. It does not matter if the drawing is a utility patent drawing or a design patent drawing, we must follow these golden rules established by patent offices such as the USPTO.

This is an article that will highlight some of these golden rules that a recruiter must follow when creating a patent illustration for an invention.

Rules for drawing patents

Showing characteristics clearly: It does not matter if you are showing a device, process or design, putting all the features of the invention on paper and that is important too precisely. The patent illustrator must accurately document all the features of the invention.

All we can say is that we need to ensure that the patent examinee fully understands the feature of the item without putting stress on the eyebrows. Not including all the details can lead to rejection of the patent.

For example, if you have a drawing of a mobile phone that has many functions, we need to show each function of the mobile phone in such a way that anyone who reviews it can have a clear understanding of the invention.

Neatness: Even if you present characteristics of your invention with precision, but the drawing has some strikeouts, overwriting and alterations, you run the risk of being rejected. Although it is not documented anywhere that your patent illustration must be neat and clean, the patent office like the USPTO wants you to present a neat, error-free drawing that is legible.

Readability: Readability is the ability to distinguish multiple letters and is another criterion for a professional copywriter to follow where each text, word, and image should not overlap its adjacent element. Failure to achieve optimal readability could lead to the rejection of your application.

Readability: Readability is another criterion that is not documented anywhere but we must follow it throughout this process. The spaces between words, between words and between lines are such that the resulting text is again visually readable.

Visually attractive: Not only do you need to have a legible drawing, but it should also be visually appealing where your drawing sheet does not have creases, holes, and wrinkles.

Use metric system: Any dimension and size information presented in a patent disclosure will be in metric inches, preferably centimeters, in the case of small devices we can use millimeters. Although the USPTO does not prohibit the use of English engineering units, they still prefer the metric system and therefore we must follow this rule as well.

Sheet Size: The size of the sheet is another important criterion that we must follow in a patent drawing. The patent office like the USPTO is very specific on sheet size and only allows two types of sheet size: a) 21cm x 29.7cm which is also called A4 size and b) 21.6cm x 27 , 9 cm, generally used by Americans.

Putting it all together, we can say that creating an illustration for invention is a science and an art that requires a proper knowledge of regulatory standards as well as an artistic approach and therefore you can do justice to your invention only if it is a experienced eraser. -person.
