Patent Attorney


Jonathan B. David is a Registered USPTO Patent Attorney who has a strong interest in software, electrical devices, mechanical devices, and other various technologies. Jonathan enjoys providing help to the inventors of large companies as well as the everyday start-up inventors.

In order to protect assets, leverage opportunities, and limit liabilities, Jonathan’s technical background and interpersonal skills empower him to clearly communicate to a broad range of clients about their immediate and long-term needs for patenting. The key areas of Jonathan’s patent prosecution practice are: patent applications, office actions, patent strategy consultation and portfolio management.

Before law school, Jonathan worked as a Radiation Physicist for Therapy Physics, Incorporated. He helped in the treatment planning for cancer patients being treated for Radiation Therapy. His interest in attending law school peaked during this time as his love for various technologies (software, electronic devices, semiconductors, and display devices) continued to grow. As a result, he left Chicago to attend Northeastern University School of Law in Boston, MA.

Academically, Jonathan has earned a law degree for Northeastern University School of Law in Boston, MA, an M.S. in Physics from the University of Illinois-Chicago, and a B.S. in Physics from the Illinois Institute of Technology. In law school, he finished course work on Intellectual Property Law and Patent law. During Law School, Jonathan completed four internships under Northeastern’s Unique Coop Program, and had a full year of legal experience upon graduating from Law School.

Jonathan has been a member of the Chicago Bar Association in Chicago. Jonathan is admitted to practice in Illinois and the District of Columbia. Jonathan is also registered to practice before the U.S. Patent and Trademark Office.

Though he has lived on the East Coast for 7 years during law school and for sometime after law school, Jonathan is a lifelong Chicagoan who is proud of his Chicago Roots. He enjoys spending time with his family and friends, traveling, running, playing basketball, and is a workout warrior. He fervently supports all Professional Chicago sports teams.
