Andy has also helped software and consumer electronics startup companies on their IP strategies, such as protecting both the function and look and feel of their products using utility and design patent applications, and organizing IP assets in preparation of business acquisition or legal threats.

Andy drafted the first patent application on Google’s Gmail III technology. He obtained a fast-tracked patent for an Iowa small business, which generated approximately $1.5 million licensing fee and $6.5 million venture capital investment for the company;

He secured a patent relating to online & offline dating in less than 100 days after filing, weeks before the dating app was made available on app store. He acquired a patent for a client within 6 months, providing the client much-needed negotiation leverage, which was used to fend off a trademark infringement claim.
