Intellectual Property

At CEBC, our industry-driven mindset fosters a culture that values the protection of intellectual property. We understand that this is essential for moving new ideas out of the lab and into the marketplace.  It not only spurs economic opportunities, it accelerates the speed at which cleaner, safer technologies are adopted for the benefit of society.
