Creating Illustrations for Inventions: The Basic Rules


We must have heard this adage “A picture speaks a thousand words.”  This goes true for patent drawings or creating illustrations for Inventions, because, drawings that are drawn meticulously, clearly, and consciously can speak much more about your invention than reams of words. In other words, we can say is that a useful patent drawing can increase the chances of approval of your patent. However, the tough part about patent drawing is that it involves various rules and regulations and a draftsperson needs to follow them religiously failing to abide by these rules could be detrimental to your overall goal.

Creating Illustration for Inventions

Every country has different rules for patent illustrations, and while creating such a drawing it is essential for a draftsperson to take into account the intended jurisdiction; still, most of them are similar in general. Thus knowing the basic rules could be of immense use for those who wish to create a drawing that is appealing, accurate, and correct.

This article is aimed at listing some basic rules of patent drawings that every draftsperson should follow. Though there are plenty of regulations that apply to patent-related drawings. However, still, we will cover only those that are of utmost importance.

Basic Rules for the Creation of Illustrations for Inventions

Ensure Inclusion of Every Feature 

While creating patent drawings for inventions, it is essential for a draftsperson to include every feature that makes up the invention without exception. Elements cannot avail protection which is not present in the drawing. For instance, if you have a mobile handset and has an innumerable number of features, it is important for the draftsperson to mention each and every element of the mobile handset.

Failing to add all the features in a patent drawing could jeopardize your overall objective. Documentation of every element of the illustration should be proper with both text and drawing to assure that the patent examiner fully understands the element of the item.

The size of the sheet should be on par with the respective patent office

Unlike standard forms of drawings, the creation of patent drawings must be present in a sheet format by from separate patent office. Failing to abide by this format could lead to rejection of your application. Patent office like the USPTO allows only two kinds of the sheet size. The sheets will be of following dimensions a) 21 cm x 29.7 cm and b) 21.6 cm x 27.9 cm.

Use the Metric System as a measurement tool

Though patent offices like the USPTO don’t prohibit draft persons from using English Measurement System. However, they encourage people to use the Metric System which people accept Universally. Any dimension and sizing information available in a patent disclosure must be in metric inches preferably centimeters. In the case of small devices, one should use millimeters.

Avoid Unnecessary Texts

While creating illustrations for inventions, it is crucial for the draftsperson to avoid texts. Those texts may be unnecessary and can produce ambiguity to the understanding.

Most of the time we see draftsperson use extra text/texts to indicate certain events in a drawing. Some examples of such documents are Open, Closed, Partially Closed, etc. While the intention could be useful such as extra added texts can jeopardize your overall goal. It is because they are not allowed in a drawing created for patents.
