Why Patent Drawings are accepted in One Country and Rejected in Another?

Why a patent drawing that is accepted in one country is rejected in another? If this is something you are wondering about then this article will be immensely useful. In fact, patent drawing rules are complex and this is why it’s important to know these rules before you submit a drawing to the respective patent office. Things become even more problematic when patent drawing rules change with the changing country. Unfortunately, that is true and hence extra precaution ought to be taken while creating drawings for patents. It needs to be ensured that your drawing is in line with the requirements of the respective patent office. Patent Drawings

why patent drawings are rejected

For example, a drawing created for USPTO can be submitted either in A4 size paper or letter size paper but for EPO and WIPO, the same should be in A4 size only and not on letter size. In South Korea, only B4 papers are allowed which are much larger than A4 or letter size. Drawings that are submitted in the paper other than B4 will be rejected outright in the Korean peninsula.

Margins that are allowed in USPTO are (top: 2.5cm, left side: 2.5cm, right side: 1.5cm, bottom: 1.5cm) while the same for Canada are (top: 2.0cm, left side: 2.5cm, right side: 2.0cm, bottom: 2.0cm). When it comes to shading in patent drawings, USPTO allows shading in them. But, in China shading is not allowed.

Similarly, USPTO allows the use of dotted lines in patent drawings but in China, dotted lines in patent drawings are not allowed.

The above mentioned are just a few parameters and there are many more variations we can find while filing illustrations for inventions.
