On the pages about the european and american patents you will find an excerpt out of my inquiry into the patent library in Rijswijk, the Netherlands, that was focused on mouthpieces and ligatures only.
These patents are divided over two pages and classified by origin and chronology. Some entries give only a brief indication of the content data; with others you can click to the entire contents in PDF-format. It is impressive to see how much creativity is documented over the years. The list has some well known, but a lot more unknown names and counts many inventions which have not survived. Probably just as much more ingenuity will never have been documented. It is interesting to see that claims of novelty that you encounter here and there prove to be entirely unjustified: most of it has already been invented and tried out long ago.
Finally it is good to remember that the patent office is not interested in (scientific) truth. That a patent exists, does not mean that the thought behind it is also a correct one.
