Services Provided



I handle all phases of patent prosecution. I have experience both as a patent examiner working for the US Patent and Trademark Office and as a patent agent obtaining patents for inventors. My background in physics facilitates understanding a relatively large variety of technologies. I have performed work relevant to patent applications related to many fields, including optics, liquid crystal display cells, ultrasound, databases, magnetic recording, video conferencing computer software, medical devices, computer security, 4G/5G communications, and computer hardware.


Some of the services I provide are:

* Writing and prosecuting patent applications

* Courses in writing and prosecuting patent applications

* Patent searching


Reasonable rates and flexible terms.
