Shortly after World War II,

Howard Keithley began a patent drafting career that spanned forty years. With the foundation he established, Keithley Patent Drafting Services was formed in 1965. Since that time, we have witnessed many changes in the preparation of formal patent drawings. During our early years, we developed a high level of drafting expertise using pen and ink. We were asked to create quality drawings from blueprints, photos, rough sketches and models. By the end of the 1980‘s we were one of the few patent drafting firms using computers for the preparation of patent drawings. As time passed, we made use of new technology, software and hardware and applied these new techniques in the creation of patent illustrations. In spite of all the advances in technology, we continue to use, on occasion, our company‘s decades of pen and ink expertise to give design and trademark drawings the final touch that technology alone may not achieve. We are well equipped to apply all aspects of illustration techniques in the most cost effective ways available. The quality continues, only the tools have changed.
