Patent law states that a patent application would need at least one patent illustration of your invention. Whether or not that invention can be illustrated in a diagram. In other words. It is compulsory to attach a diagram of your invention with the patent application. Even if it does not assist in understanding your invention. If you want your patent application to be strong and better than others. It is advised to include as many patent drawings as possible.
We all need to understand the importance of patent illustration Services. At the time of filing your patent application, whatever you attach with it makes up the totality of the disclosure. Needless say, the reality is that patent illustrations/drawings/diagrams are worth no less than a thousand words, probably much more.
