Services include creating proper documentation for use when applying for a patent during the patent application process. Hand illustration and 3D CAD modeling are used to create these types of drawings. I am extremely efficient in creating these types of drawings. These are generally one time projects and are normally quite short which is why I require the higher bill rate. Because of my efficiency, on most simple designs, I can provide top quality drawings for less cost than you can get from a large patent illustration firm that charges by the view. I can do both Utility and Design patent drawings.
