This Excel sheet lists the patents related to both Carl Neracher and the Neracar motorcycle. Some text is corrupted, probably due to the process of Optical Character Reading which apparently has been used.
Some of the patents show very interesting, detailed and useful drawings.
The last patent listed does not relate to the Neracar motorcycle.
Please note that the listed patents do not necessarily relate to the Neracar Model A.
Thanks to Giovanni Orlando and Joost Heesakkers, who provided me with patent listings.
