A new breed of wind turbines is coming!

Take a simple idea and take it seriously

I filed a patent application for the turbine shown above with the Italian Patent and Trademark Office on Oct. 30, 2014. On July 2, 2015, the European Patent Office published the search report, stating that the subject of my independent claim is new but rejected the application for 'lack of inventive step'.

In my opinion, the rejection was justified as the examiner found that US patent 8,430,637 (www.google.com/patents/US8430637), issued a year before my application, discloses a wind blade that 'could be given the shape' of mine. However, I believe the inventor of US patent 8,430,637 did not realize that his blade could be shaped like mine.

Moreover, his invention bears a striking resemblance to a garden spinner that was likely already in commerce before he filed his patent application. If this is true, his patent may be invalid, either in whole or in part. You can find the Deco garden spinner (previously sold on www.fishpond.com/Toys/Deco-1-Wind-Dazzler-Garden-Spinner-US-Toys/0786782572187) for reference.

Given these circumstances, I converted my patent application to a design patent application, and I was granted the Italian Design Patent No. 283327 on March 27, 2017.

For those interested in building a simple, inexpensive, and lightweight wind turbine at home, I have included the patent drawings. Three embodiments of the turbine are shown, with the first one being the simplest, the second one unnecessarily complicated, and the third one likely the most efficient.

However, please note that this is not 'yet another revolutionary wind turbine.' It may not surpass the efficiency of today's highly optimized wind turbines, but it is cost-efficient since it costs next to nothing.
