Last chance to acquire two patents EP 2 594 824 - Self-adjusting sprocket

The use of this "self-adjusting sprocket" means a great financial saving for operators of ALL chain-driven systems, as the chains last much longer and the work involved in changing the chains is considerably reduced.

The previous patent has been in continuous operation for over 19 years together with two chains from Ketten Wulff. 

Perhaps you are interested in creating a second "mainstay" in Germany and/or the Czech Republic by selling this patented "self-adjusting sprocket" in these two countries without competition.

For a few weeks, the two industrial property rights for Germany and the Czech Republic will still exist. After that I will give up the rights for the Czech Republic and then the patent MAY be built and used all over the world with one exception, and that is and remains Germany.

You can find all information about this sprocket on my homepage: as well as in my books, which you can download for free:

" Book: "Inventors with long breath" as PDF file (German)
"Book: "Inventor with long breath" as PDF-file (English)


I think that in times of Corona there are very, very many companies that are interested in saving costs in order to survive and be competitive in the long run.

Furthermore, climate change and the conservation of environmental resources are still important.

At this point I would like to point out again that I do not build and distribute the sprocket, but the patent is for sale.

If you are interested in the acquisition of the patent, I would be pleased about an appropriate written purchase offer.
