The Three Types of Patent/Trademark Drawings

So what makes PowerCADD and WildTools so perfect for this (or any) drafting?  I began with ClarisCAD because it made sense and worked the same way that humans actually think (which is, of course, the same reason I prefer the Reverse Polish Notation Operating System of the Hewlett Packard calculators, but that's another story).

In this business, there are three types of entities that can be prepared by an illustrator for the USPTO.  The first is the Utility Patent which is the protection of the idea behind how a thing works.  This can be further subdivided into Process Patents which protect a process such as manufacturing or production.  In these cases, scale and actual size are unimportant, and dimensioning of the drawing is prohibited unless the actual dimensions are inventive by their nature.  Only the concept of how a machine or process works is important.  Many times the actual machine does not exist at all except in the inventor's head, and it's my job to get inside there and get it out for all to see.

It can get pretty hairy.  Because we are drawing conceptually, WildTools is perfect.  In particular, I used to shy away from a 3D representation, because everything had to be manually skewed to the various planes, and this was very trial and error.  Now I can take a photograph of a machine and scan it, then place the scan onto a drawing layer and draw lines for the major axes.  From PowerCADD's Edit Window I can determine their angle and input these values into the WildTools 3D Cube and take off tracing the invention with everything constraining itself to the proper angles.  Not only do I not shy away from a perspective view any more, I actually prefer it because it is usually much more illustrative than several orthographic views.

The second type is the Design Patent whose purpose is to protect nothing other than the appearance of an object -- the way it looks. In this case there are no reference numbers pointing out inventive elements; there are only Figure Numbers denoting the (usually) six orthographic views plus a seventh perspective view.  The only requirement here is complete disclosure of the object's appearance and whatever it takes to reveal it clearly and completely.  A ball or sphere would, of course, have only one required view.  Other inventions of greater complexity may require more than the seven views and can include more than one perspective and even sectional views are allowed if they are necessary for full disclosure.  Again, PowerCADD and WildTools are doubly important in producing these with speed and accuracy.  My clients can't believe I can produce the drawings at all sometimes, much less with the speed with which they can expect them.

Third is the Trademark Drawing.  This can be a logo, slogan, words or shapes that constitute a unique appearance that will always be associated with a particular product or entity.  These must appear on an 8 1/2 x 11 drawing sheet no bigger than four inches square centered one inch from the bottom of the page.  For the longest time colors could be represented by 8 different hatch patterns if the colors were considered part of the Trademark.  No one would recognize the Pepsi logo with a green top and yellow bottom with orange words.  This requirement has been suspended recently, and only shapes are to be drawn with the colors indicated by the text of the application.
