Optimism, curiousity spur Knox's inventions

“Sounds like fun. Let’s try it!”

Those are the words of Wayne Knox '79, '84 (PhD), and they, in a nutshell, sum up his career as a researcher, and help explain why he’s just been elected a fellow of the National Academy of Inventors.

A professor of optics at the University of Rochester, Knox has been awarded a slew of patents – 50 in the US, and another 150 or so worldwide. Most recently, he co-invented a potentially game-changing way of correcting vision by noninvasively modifying the cornea with femtosecond lasers. It also works with contact lenses and intra-ocular lenses.

But he insists he would be “equally excited” about coming up with a better hot sauce in his kitchen.

So what does it take to be a successful inventor?

“It helps to be optimistic,” Knox says. “It also helps to be infinitely curious. I am infinitely curious about some of the tiniest things you can imagine.”

Filling the house with smoke

knoxKnox grew up in a household steeped in curiousity and invention. His father, a physics professor at Rochester, would grab electronic equipment that was about to be discarded and bring it home instead. “My older and younger brothers and I would take them apart into the smallest units,” Knox recalls. “A whole wall of the basement was organized as resistors, capacitors, vacuum tubes, and high-voltage transformers.”

The teenagers would then build their own gadgets.

“It was just pure discovery. I really had no idea what was going to happen when I turned these things on,” he says. “Several times I filled the house with smoke.”

While attending East High School, for example, he was impressed with a carbon-arc spotlight he worked with in the theater. Back home, he grabbed some transformers from the basement, and built his own carbon-arc spotlight at his desk in his bedroom. “When I turned it on, it burned a hole in the desk and the desk started on fire.”

But more often than not, the gadgets worked. “I built a regenerative short wave radio entirely by myself,” he says. “I wound all the inductors by hand around little wooden blocks, just by following what was in the books we had.

“Somebody really needs to give me a job,” Knox recalls thinking to himself at the time. ”I could really invent some useful things.”

It wasn’t long before he proved it.

His first patent while an undergraduate

Knox received his first patent while an undergraduate, working in the ultra fast laser group of Gerard Mourou at the Laboratory for Laser Energetics. This was during the period before and after LLE moved to its existing facility.

Knox, described by Mourou as an “exceptional undergraduate student,” used high power picosecond switching to develop a jitter free streak camera.

“For me, the most important part of that was -- even as an undergraduate -- being treated like a full member of the team,” says Knox. “They ultimately gave me my own lab at the new facility. It really showed how, as an undergraduate, you can do some serious research, and even get a patent. How wonderful is that?”

More patents followed after Knox completed his PhD at Rochester and joined AT&T Bell Labs in 1984.

“There could not possibly have been a more logical or better place for me to go,” Knox says. “The research environment at the University of Rochester had completely prepared me for maybe the toughest research environment anywhere in the world.”

Big companies tend to accumulate valuable patent portfolios – as many as tens of thousands of patents “that they use as currencies to interact with other companies,” Knox says. “They call it patents by the pound.”

That was especially true at Bell Labs. When Knox arrived there, researchers received $100 for each patent they generated, Knox says. When IBM topped Bell in number of patents one year, the checks were increased to $1,000.

About two-thirds of Knox’s US patents resulted from his work at Bell Labs in telecommunications, fiber optics, optical switching systems, and ultrafast lasers – first as a postdoc, then as a member and distinguished member of the technical staff.

During his last four years at Bell, Knox was Director of the Advanced Photonics Research Department. The company was in the process of selling off various divisions, and Knox’s responsibilities included helping to decide which of the patents held by the company should be kept, and which should be sold.

'Maximize your creative energies'

By the time Knox returned to the University of Rochester in 2001 to become director of The Institute of Optics, he had gained a deep understanding of the importance of patents in the corporate world – and a real appreciation for how patents can “capture the value” of a good idea for the benefit of an organization.

He has continued to apply that knowledge as an academic researcher, teacher, and even as an expert witness in patent cases.

For example, soon after returning to Rochester, Knox began a successful collaboration with Bausch and Lomb, using ultrafast femtosecond lasers to modify contact lenses, and even to noninvasively modify intraocular lenses while they’re still in the eye.

When Krystel Huxlin, the James V. Aquavella Professor of Ophthalmology, suggested an even more radical notion -- using the lasers to correct the cornea itself, Knox’s response was “Sounds like fun. Let’s try it.”

It worked. And, thanks to a fortuitous sequence of events, their discovery has led to the creation of a startup company, Clerio Vision Inc., with Knox as chief science officer.

With a robust portfolio of patents licensed from the University, and seasoned serial entrepreneurs at the helm, Clerio Vision has “taken off like a rocket,” Knox says. The company employs more than 50 people and is building labs and offices on University Avenue in the city of Rochester.

Not surprisingly, in the Optical Engineering Senior Design class Knox teaches at The Institute of Optics, patents are a big part of the discussion. “The important thing to underscore is, if we have a really good idea, let’s make sure that we properly capture the value of that idea for the organization that we’re working with, whether it’s a company or a university,” Knox says. For researchers, it's important to "know what a patent is, how the patent system works, and what your responsibilities are."

Beyond that, he says, "it's OK to be a dreamer." His advice to students, faculty members, and would-be inventors and entrepreneurs:

“Make sure that you are maximizing your creative energies, because in your life that will be the thing that’s worth the most to you. That doesn’t just mean writing patents, but coming up with things that the world hasn’t seen yet.”
