The idea was to provide users with a modern, user-friendly avenue to attain the earliest possible form of patent protection while providing inventors access to patent professionals when requested.

After studying engineering and patenting an invention of his own, Dan became a patent attorney at a downtown Los Angeles law firm.  As an inventor himself, Dan wanted to help other inventors protect their ideas.  Through the process, he recognized that obtaining patent protection could be quite intimidating and costly.  For that reason, Dan has devoted his career to helping his clients navigate the complex patent system.  Dan's professional experience, skill, and dedication to his clients througout his career earned him the rating of "Super Lawyer" by the rating service of the same name.  This rating service selects attorneys with a high degree of recognition and achievement in their field.  The Los Angeles Business Journal also recently acknowledged Dan's high level of achievement, naming him one of the most influential lawyers for digital media and e-commerce in Southern California.

In 2011, with the introduction of the America Invents Act (AIA), the United States patent laws were changed to support a “first-to-file” system, which means that inventors are now at a high risk of losing their patent rights if they do not file their ideas as soon as possible. With this increased risk to his clients in mind, Dan created a simple, cost-effective solution to protect their ideas.
