Patent drawing is considered as one of the most important elements of a patent application as it streamlines the whole patent granting process. With an aesthetic patent drawing, we can speak a lot about our invention without writing a whole bunch of texts. However, applicants should know the proper way of formatting a drawing otherwise it may be rejected outright by the patent office as they are very selective about the formatting of a drawing that is accompanying a patent application. Below mentioned are some of the rules that a draftsperson should take into consideration while formatting details of utility patent drawings.
Formatting Details of Utility Patent Drawings
- Avoid Unnecessary Texts- Most of the time we see draftsperson use extra text/texts to indicate a certain event in a drawing. Some examples of such drawings are Open, Closed, Partially Closed etc. While the intention could be good such as extra added texts can jeopardize your overall goal as these are not allowed in a drawing created for patents.
- Avoid Coloring your Patent Drawing- Some draftspersons that are new to the domain of patent drawing use various color combinations to make their drawing creative and appealing. While it is true that coloring can liven up your creative work they are not allowed in drawings that are meant for inventions. While some patent offices like the USPTO allow shading patent drawings, there are many patent offices like SIPO (State Intellectual Property Office) for People’s Republic of China doesn’t allow shading in patent drawings.
- Lines should be dark, uniformly thick, and well-defined- Lines drawn in a patent drawing should be given extra consideration as these are one of the most important components of a patent drawing. There are myriad of lines that are used in a patent drawing and each has its own definition and meaning. For example, a dotted line has a different meaning while the dashed and continuous line has a different meaning. Such things should be considered while creating a patent drawing as they can either make or break your whole attempt.

- Maintain the Proportion– It is very important for a draftsperson to maintain proportions of every element used in a drawing. In other words, we can say is that each element of the drawing should be in the proper proportion to the drawing as a whole and to other elements. The exception is when an element must be enlarged to provide clarity about certain details.
- Mind the size of the text- Patents are structured documents and every element should be in line with the respective patent office. Same goes true for Numbers and letters those are used in a patent drawing. Usually, size of the text should be 0.32 cm for United States Patent office.
- Carrying multiple drawings- As per USPTO, multiple drawings are allowed in a single sheet, however, draftspersons need to ensure that the cleanliness of the drawing is not compromised.
The above formatting rules are mainly used for United States Patent and Trademark Office and except for some minor changes, it remains almost same for most of the countries. Viewing the complexities in creating drawings for patents it could be overwhelming for people who are new to this domain and thus should take help of experienced patent illustrators who have been working in this field for a long time.
