If I had known that this topic would have caused such a stir then I would have never posted.
The same thing has been going on the in the piano industry for over 150 years. Classic example is that of Steinway and Young Chang. When Young Chang came out with the model PG 213, Steinway looked at the scale and found it remarkable similar to the Steinway model B. The most notable difference was the case was 1" longer but the scale of the piano inside was a basic copy of the Steinway B. The icing on the cake was the designer of the PG 213 was a designer that use to work at Steinway. This caused a huge uproar with Steinway. Young Chang defended its self with showing the design being truly different. How different? The thickness of an American dime. Steinway couldn't touch Young Chang for so many reasons beyond what I'm willing to explain.
Flat out copying has been going on for decades in the the piano realm from pedals to duplex scaling to action ratios so it's no surprise it happened to Sebo and Hoover. Copyrights and patents are tricky things and you'd surprised what one can get away with. After all we wouldnt have the modern piano today is makers didn't try to copy the best features of their competitor.
