About me

I am a registered patent attorney with the U.S. Patent and Trademark Office.  I specialize in preparing patent applications, performing freedom to operate searches, and searching for inventions that are similar to my clients' inventions.  


I also work with clients in registering their trademarks and copyrights as well as asserting their rights against infringers. 


I have a Chemical Engineering degree from Purdue University and I worked for Exxon Mobil as an engineer for five years.  I attended the DePaul College of Law in Chicago.
