Sauer Energy Inc. (SEI) is a BCO Hydrocarbon Ltd. (OTCBB: BCOZ) subsidiary that develops and produces home and enterprise scale vertical axis wind turbine (VAWT) systems. SEI yesterday announced that the United States Patent and Trademark Office has issued Patent Number U.S. 7798766 for the company’s wind turbine blade design.
This patent covers the utility function of the company’s wind turbine blade design and its conversion of wind into useable energy. The patent is directly related to and extends the coverage of the company’s first patent granted. As a “utility” patent, the company said it is considered more complex, comprehensive and valuable than design patents.
“These patents and patents pending establish that our cutting edge technologies are protected and add substantial value to the Company’s growing intellectual property (IP) estate. They also reinforce our competitive market position by erecting major barriers to entry,” Dieter Sauer, president and CEO of the company stated in the press release.
SEI has U.S. patents pending for its unique air disruptors and air strakes, which are key components of its vertical axis wind turbine. The company said it is currently working to file several more patent applications for various features and applications for its proprietary technology.
Sauer noted the value of the company’s patents and explained the functionality of the technology.
“Sauer Energy’s integrated, diversified multiple patent portfolio strategy creates an IP estate far more valuable and formidable than the sum of its parts. The design effect of the blade will give it a superior performance by way of capturing wind and the (utility) extraction of power,” Sauer stated. “Most obvious to the casual observer, are the air disrupters on the drag side of the three-bladed turbine. The pattern on this side is to create less resistance with a boundary layer. This will create a maximum rpm with less friction. The inside of the blade itself contains air channels called strakes, which will guide the airflow and propel the captured air through a ram jet port, through the blade and on to the next blade. This uses airflow to its maximum advantage.”
Sauer’s patent portfolio includes: U.S. 597028S – Design patent issued: Blade Layout concave/convex, vertical axis; U.S. 7798766 – utility patent issued: Functional and application to convert wind to energy; patent pending design filed: Features the air disruptors on the drag side of each blade, inclusive. The front-side inside of the blade air strakes, which channel to direct the wind flow into a ram jet and the leading edge blade is also included; patent pending utility filed: Aerodynamic effects for the conversion of wind into power; patent pending design application: Blade structure; patent pending utility application: Function and use; and foreign patents pending.
