Wendish Patents Found to Date

Wednesday 04 July 2018 at 4:27 pm.

Below is a list of all the patents I have found to date that Wends have either been awarded individually or working with a group. The names of those of Wendish descent are in bold type. The list is in chronological order and each entry has the names of the patent awardees, the name of the patent, patent number and the date the patent was awarded. Thank you to all who have helped me compile this list. 

I have copies of each of these patents and will gladly send them out to anyone who requests one or more of them.  If anyone reading this knows of someone else who is Wendish and was awarded a patent but is not part of this list, please contact me and I will be happy to add them.
