Client Testimonials

Yesterday morning I was sitting in a meeting and in the middle of everything realized we had something we needed to protect. I called Maryanne and we got something filed by 11:00 last night. That kind of work ethic doesn’t exist in most law firms.

Maryanne is very good. She’s very responsive and does a good job filling in the pieces without doing too much searching. What she sends me has good commentary and the discussions are good.

I have the ability to brainstorm with Maryanne and really discuss things we are doing so together we can come up with the best solutions.

We are blessed to have Maryanne. She is a relatively young partner and really hard-working and smart. She’s a very effective patent lawyer.
