Depeng Bi

I would strongly recommend Mr. Bi for anyone searching for a patent attorney. He was very knowledgeable and enthusiastic in filing my patent. He answered all my questions about the patent filing process. I was very impressed how accessible he was even the after hours. Anyone looking for a good pa...tent attorney should contact him at his law office in Naperville, IL.

I started my own business almost a year ago and reached out to Edward for legal counsel. I have utilized his services on four occasions - primarily for copyright and trademark needs. I have found him to be thorough, responsive, and someone I can depend on. He takes the time to explain what the alt...ernatives are as well as what the next steps, if any, will be. While I don't have extensive experience in working with legal counsel, his rates were what I expected. I will work with Edward in the future and would recommend him to others.

Edward as he likes to be called, was the lead attorney for my patent application in 2014. We had two refusals from the patent office due to what seemed to me to be unfair prior art allegations. In each case, Edward came up with a strategy to refute the findings. In the end I was able to secure a pa...tent for the product which included the next advancement in the technology which will be added to the current product. So it will protect my IP in the long run. I was very please with his efforts and would recommend him to others for patent issues as well.

Mr. Bi was hired in 2011 by our company to help our application for a patent in the fledging 4G wireless technologies to offer advanced quality of service in order to secure end-user experience. Besides being responsive and keeping us informed, he especially impressed us for the technical specificati...ons and claims he drafted that were associated with profound understanding of wireless technologies. His engineer background is really a big plus in addition to his legal skill, and we are confident that the claims will fully protect our intellectual property.

My employer hired Mr. Bi to file a patent application for my invention in 2011. Mr. Bi has been very responsive in setting up meetings and updating documents based on everybody's input. With his solid background in software and engineering and his due diligence, Mr. Bi was able to fully understand my... invention quickly and drafted excellent claims in the patent application. We are confident that the claims will fully protect our proprietary technology. Overall, Mr. Bi is a trustworthy and detail oriented lawyer who can integrate engineering and software inventions into highly effective legal claims.
