Illinois Patent Lawyer
When you have an invention to be patented and are in need of an intellectual property lawyer to handle your patent application, contact Don Ersler for all of your patent protection needs. Just because you are a resident of Illinois does not mean that you must have a patent lawyer in Illinois. I am based in Milwaukee, Wisconsin, but because patents are a federal matter, I can prepare and file patents for inventors from any state. With lower overhead costs than that of a Chicago patent lawyer, I am able to offer lower rates for my services.
If you are seeking a patent attorney in Chicago or elsewhere in Illinois with extensive experience in the industry, look no further. I will give you a free initial Illinois patent consultation as well as a flat fee quote for all legal needs pertaining to your patent protection. I offer patent searching, preparation, filing, infringement analysis, litigation, and licensing all at a lower cost than the patent attorneys in Illinois.
I have over 18 years as an intellectual property lawyer handling mechanical, electrical and software inventions and 12 years prior to that as an electrical and mechanical engineer. This diverse experience combined with my work with inventors, design departments and corporate attorneys around the country gives me the tools to handle your patent application process and all that goes along with it. My experience speaks for itself. You can see samples of my work by viewing more than 360 patents issued to my clients. You can also view samples patents from clients in the state of Illinois by clicking on the following patent numbers: 6,263,820, 6,568,114, D484,942, 6,752,099 and 7,721,568.
