Frank J. Schumacher

Frank J. Schumacher IV is admitted to the Washington State Bar and is registered to practice before the U.S. Patent and Trademark Office.

Frank has earned a Bachelor of Science degree in Analytical Chemistry, focusing on mass spectrometer development, from the University of Washington. He has also earned a Masters of Science degree in Electrical Engineering from the University of Washington focusing on micro- and nano-scale devices, and optics. Frank earned his Juris Doctorate from Seattle University School of Law.

Prior to practicing law, Frank was employed at the University of Washington as a Research Scientist in the Chemistry department. This work focused on development of mass spectrometry instrumentation and ‘soft landing’ separatory devices for combinatorial chemical assay analysis.

Frank has also conducted research into the development of digitized light sources for optical microscopy. This research was used for the special and temporal control of ATP conversion in biomechanical “nano-motors” in conjunction with a joint University of Washington Bioengineering and Electrical Engineering department project. His master’s research thesis is titled “Adaptive Imaging for Optical Microscopy through the Use of a Digital Illumination Module.”

Through his many years at the University of Washington, both as a student and employee, Frank experienced patent prosecution from the Inventor’s perspective. During his summer associate and contract attorney positions with patent and IP law firms, Frank has brought this “inventor’s perspective” to his practice of patent prosecution. Frank has worked with a wide range of technologies in the mechanical, electro-mechanical, optical, medical device, computer hardware, software, analytical instrumentation and semiconductor field with an emphasis in prototype level instrument development.

Professional memberships include the Washington State Bar Association, King County Bar Association, Washington State Patent Law Association, AIPLA, and Washington Software Association.
