Client Testimonials
“I have worked with Eugene for many years on all types of patent search projects from drafting provisional applications to creating massive support documents for accelerated examination applications. In all cases Eugene and Sherman Patent Search provide on-target search results in a timely, economical manner across a broad spectrum of technologies. Sherman Patent Search has proven to be highly adaptable on project requirements and is worthy of your search dollar.” – Nick Witchey, Ph.D., Reg. Patent Agent #63,481, Head of Intellectual Property
“In my 25 years of practice, Sherman is the first patent search firm that I rely upon consistently. Sherman impresses me with high quality searches for me in the electrical, software, medical device and mechanical arts. They locked me in, though, with their report format. They have an uncanny way of knowing what we want and their reports make the attorneys in our firm more efficient.” – Steve Sereboff, Founding Partner, SoCal IP Law Group
“Patent searches are a critical part of our work – SPSG is our go-to professional search firm. They’re efficient, comprehensive, and take a hands-on approach with their operation. SPSG combines the 3 things you look for in a search firm: timeliness, accuracy, and reasonable rates. Highly recommended. I have not used a different search firm in the last two years, whether it is for right to use, patentability, or invalidity. And I and my clients are much more comfortable using a domestic search firm rather than one where our clients’ confidential information gets sent offshore.” – Jeff Sheldon, Managing Partner, Published IP author
