Lesley Wallerstein earned a science degree from the top technology school in the country. For several years, she examined international patent applications in biomechanical engineering devices, pharmaceuticals, alternative energy technologies, cutting edge textiles and sporting goods. She has a keen eye for identifying inventiveness and an unparalleled command of the written word.
I came to Lesley with an innovative project requiring an ambitious time frame. Upon an initial consultation, Lesley thoroughly understood the project. I'm grateful for the flexibility that Lesley has shown regarding concerns common with small to medium sized entrepreneurs. She has been accessible and responsive throughout.
Shark Tank has made invention really cool.and it is! But there is a whole other side of building a business around an idea that can be, in all fairness, dry and tedious. There are laws concerning safety, taxes, and intellectual property that come into play and that do affect a business' bottom line.
I hope you are staying healthy. As a patent and trademark law office, I am considered an "essential service." I remain open and working as usual. I will continue to post more serious law firm news. But while we are all social distancing, I offer some new, not obvious, and decidedly lighter fare. Wait until you see who invented this.

This was my first time trying to obtain a patent. I did research before contacting lawyers and I spoke to a few lawyers before I found Lesley. I hired her to conduct a limited patent search and to file a design patent. She was extremely knowledgeable and helpful throughout the entire process. I felt completely comfortable as she handled everything as soon as I was able to explain the concept and provide a basic visual representation.
To any beginning inventors, make sure you do your homework and understand the process. It’ll make finding a great lawyer like Lesley that much easier and will ensure

I have submitted my own patent applications in the past, and it is very time consuming and difficult to do at times. Attempting to make time for writing patent applications AND running a growing business definitely poses a challenge.
I had a need to have someone fill a void that I had for my patent applications, simply because I was unable to do these tasks efficient and accurate enough on my own. The Law Office of Lesley Wallerstein provided confident answers to my questions, prompt service, and through applying her wealth of knowledge in the field - ultimately led to our awarded patents.

Lesley helped my business, Mission 2 Organize, get our trademark registered with the United States Patent & Trademark Office. She walked us through the process and even provided us with unsolicited advice that was invaluable. I always knew I could reach out to her and get a rapid response. If you choose Lesley to assist you, you will not be disappointed!

Lesley made a HOUSE CALL to my home so that I could finish trademark search before year end. She was easy to talk to, and I understood what I was getting. When we got the report, she suggested who I needed to call to resolve firm naming conflicts. The suggestion was spot on. I resolved the conflict, and made a new contact!

By far the best service and experience we have had working with a Lawyer! We have reached out to two patent Lawyer prior to working with Lesley and they both told us we could do little to patent our product. Lesley provided us with options to protect our product and advise us on how to move forward with ensuring our designs were protected.
She followed up with us every step of the process and was readily available to answer our questions. Truly concerned with your needs first.
