Patent Drawing Rules

The main and ultimate objective of a patent drawing is to illustrate the complexities of the new invention being proposed for proper registration. Every national or international patent office has certain recommendations and instructions for patent drawings. These recommendations are related with the size of the drawing paper, type and quality of the paper, type of the ink to be used for drawing, margin standards, drawing scale, views, uses of columns and arrows, etc., and other necessary information for making the patent drawing self-illustrative, elegant, and most impressive to the officials of the concerned patent office. These pieces of relevant information about how to patent a drawing, are mandatory for patent registrations.
