Patent drawings
Clarifying the state of the art
The invention, the possible embodiments of the innovation and the state of the art can be clarified and explained by means of a patent drawing.
Sketches, technical drawings, photos, CAD data, vector graphics or images of a prototype are permitted - all of which can make it easier to understand the invention.
However, it is not a mandatory component when filing a patent application.
Standards for the submission of drawings
The guidelines of the respective patent offices apply to the creation of a patent drawing.
The drawings designed by the inventor are often used.
If schematic representations are also required, these can be commissioned from companies specializing in patent drawings.
The main requirements of the GPTO for a patent application include
- several images are possible
- work exclusively with black paint
- hatching when marking cross-sections and cut surfaces
- representation of reference lines must be curved
- no exact dimensions on the drawings
- no explanations on the drawings, except for drawings relating to the state of the art (in this case the note "state of the art")
