With new patents granted in Chile, Hong Kong, Philippines, and Vietnam, Detroit’s Sharrow Engineering now has a total of 78 patents to protect embodiments of its Sharrow Propeller, allowing the team to deliver more efficient propeller technology in an increasingly large and worldwide market.

“With these new patent assignments, we are positioned well for manufacturing, joint-venture and licensing opportunities in multiple market segments around the world for our propellers,” says Greg Sharrow, founder and CEO of Sharrow Engineering, who is working to more than quadruple the company’s manufacturing output by 2023.

In addition, the company has filed more than 100 patent applications with the U.S. Patent and Trademark Office (USPTO) and foreign patent offices to protect the intellectual property rights for the Sharrow Propeller.

Already, patents have been awarded in the U.S., Australia, Canada, Chile, China, Europe (14 countries), Japan, Mexico, New Zealand, Philippines, South Korea, Singapore, South Africa, Russia, Taiwan, and Vietnam — with many other patent applications pending in countries around the globe.

The Sharrow Propeller has garnered widespread attention for its new design that it claims offers some of the largest improvements in fuel efficiency and performance that the boating industry has ever seen. Sharrow Engineering won the Innovation Awards at the 2020 Miami International Boat Show.

Consumer demand for the new Sharrow Propeller is rooted in the fact that the design offers a host of performance improvements including higher speed per rpm, better handling, reduced vibrations, and a stronger propeller in general that it is as much as 40 percent more efficient than the industry-leading propeller designs according to Sharrow.
