Many types of patent applications require a drawing by law, and this can be a crucial step to securing the success of your product. A patent drawing is useful in providing an understanding of the product and removing ambiguity.
A patent drawing is different to other product design drawing such as 3D renderings and photo realistic virtual prototypes, because a patent drawing contains reference numerals to draw the attention to the parts in the figure. It usually shows the product in an exploded view which shows how each separate part comes together to create the product.
There are standards required when submitting a patent drawing such as:
- Page layout must be A4, preferably in portait orientation, and printed on one site only.
- The pages must be sequentially numbered beginning with “1”, and numbers must be centred at the top of each page, and be located 0.5cm from the margin.
- Paragraphs should be left aligned, numbered, and the spacing between the paragraphs should be at least twice the intra paragraph line spacing.
- Each sheet of drawing must have the top and the left margins set at least at 2.5 cm, right margin set at least at 1.5 cm and bottom margin set at least at 1cm.
- Fonts should be a minimum font size of 12 points, solid black colour, and be chosen from a set of preferred fonts.
There are numerous additional requirements which relate to titles, sub-titles, the order that should be used within the description and how claims and amendments should be portrayed.
The particular requirements of the Patents Act and Patent Regulations can make writing a patent specification a daunting task, and that is why it is recommended to use a patent drawing professional in meeting these requirements.
