Shading Techniques

Accurate representation of an object’s precise shape is crucial to the success of a design patent. Our team of artists, graphic designers and engineers maintain a scheduled regime of training exercises, even after 10 years on the job, to make sure their skills are up to date.

We use a variety of illustration techniques to suit your needs/criteria. Below are some drawing approaches selected according to the specifics of each case given to our team:

Standard Line Shading - This is the most often used approach to surface shading. This style is preferred because it easily illustrates the precise geometry of a figure. Examiners prefer simple black-on-white illustration methods.

Stipple - The advantage of stipple shading is its organic depiction of a design's shape using varying densities of dots to define the figure's form. Designs that defy the standard line drawing approach may benefit may from the use of stippled shading. And the good news is that, because it is black dots on a white background, it readily passes examination as a black-and-white drawing. No special use-of-color petition is needed, nor is there an added USPTO fee.

Photos - It is very common for the informally filed images of a design or utility patent to be low quality photos as seen in this example. These will be rejected due to poor image quality. In some circumstances, examiners will allow the use of high quality photos in place of line drawings. Our skilled and well-equipped photographers are adept at capturing the images needed to assure a ‘pass’ from the examiner.
