Thanks.

Do you have plans to add more patents? If so what are you interested in? Everything related to this board? Any language or just English?

Yes I am hoping to update the patents.

I am also looking to include patents in other languages.

I'll make for you a list of the patents I have found so far.

Thanks for the file . Over 500 pages from 19 century topresent day auto dialers for combination locks . Did yout this together ? Good job ! I lokforward to somegerman patnents >

No I didn't put it together. It was downloaded from a site called ezpicking... long dormant. The user lance98 did the work of putting it together.

Many countries publish patents granted to inventors in their country. There are international identification numbers that have been agreed on so its relatively easy to search every where for patents covering one topic.

https://patentscope.wipo.int/search/en/search.jsf is one of the search engines that can be used.

Lockpicks is but a very small category of patents . If there is interest we can do a much deeper tutorial on categories of interest to a locksmith.

Class 70 is the category for locks....

This shows the breakdown of 70/0000 https://www.uspto.gov/web/patents/classification/uspc070/sched070.htm#C070S394000

The patents from Kromer I have found so far. Kromer is probably the most famous of the old German lock manufacturers due to their Protector lock. Kromer as a lock company does not exist anymore, but Lebtig is still producing the Kromer locks with the same high quality.

Will send you a messaging with a link to the PDFs. Getting German and European patents is a pain compared to US patents.

An old German company which also produced a very famous lock is Bode Panzer. The key of their lock (Tangential) is quadruple bitted and looks like a mace. Unfortunately my search for any patents for their lock was without success so far.
