  • Frederic G Lemberg

    I have known Mr. Knoller for over 40 years. Some years ago we worked together at the same law firm. Later, ,while we were no longer at the same firm we worked on the same side of federal court litigation involving patent and copyright infringement issues. Mr. Knoller is extremely well qualified to handle any and all matters he undertakes. He is hardworking, creative, and well prepared. I recommend him to anyone looking for representation.
