  • David B. Sandelands

    I endorse this lawyer. I worked with Ron for several years and observed his expertise in patent prosecution and litigation matters. Ron served as a wonderful mentor to me in my early years of law practice. I would not hesitate to consult with, or refer to him any matter involving intellectual property. Ron is a first rate intellectual property attorney.
