About Us

It all began with an ink pen, a drafting board and the urge to draw and Dakatec was on it’s way. What started in 1989 as a tedious service based on Ink Pen and Bristol Board technology (old school drawing by hand), Dakatec has now evolved into a lean and efficient electronic CAD practice.

Since those early days we’ve grown into an industry leader with an in-office staff possessing over 50 years of combined experience. We have provided over 150,000 sheets of drawings to individual inventors, IP law firms, attorneys and patent agents with a nearly flawless approval record.
