IN THE FOOTSTEPS OF THOMAS EDISON
For Novatek, Thomas Edison's drive to research and invent is the paragon of a company mission. To innovate at the speed of an Edison, Novatek has developed a system in which multiple disciplines are grouped into labs and departments, each connected through a set of problems.
This system allows for true collaboration and the leveraging of genius by creating an interdependent set of projects that benefit from the disparate approaches that stem from different professional and academic backgrounds. The labs are all housed on the Novatek campus, and with facilities running around the clock, spontaneous collaboration is an inevitable result.
As with Edison, Novatek takes the resulting technologies and licenses them to clients by field of use.

NOVATEK'S PATENT PROCESS
Edison's method of examination and experimentation set an unprecedented pace of invention, yielding 1,093 patents over his lifetime. Novatek takes great inspiration from Edison's achievements, and the 703 patents listed below show that the company has generated its own momentum as an invention engine.
The key to Novatek's success is its fine-tuned intellectual property process. All work is conducted in-house: the brainstorming, the prototyping, and the legal legwork. This allows Novatek to fully realize ideas from concept to proof of concept, generating valuable intellectual property along the way.
