According to the website, this is how the technology is actually implemented:

The Sharklet surface is comprised of millions of microscopic features arranged in a distinct diamond pattern. The structure of the pattern alone inhibits bacteria from attaching, colonizing and forming biofilms.

It's interesting that the pattern structure itself is the technology.

Hate to think that too many or any sharks were killed or tortured during the making of this product, but that's yesterday's and today's reality. Maybe tomorrow will be different.
