Good day, all, and happy Friday,

Has anyone succeeded in researching patent 97101? According to https://www.vintagewatchstraps.com/aegler.php , this patent, issued 1922, protects the design of the then novel crown wheel core.

I'm wondering specifically if the patent was renewed, abandoned, licensed, or infringed upon. From what I've read, Swiss patents may be renewed up to 20 years, but an application for renewal must be submitted before each expiry. Thus, if it had been renewed up to this limit, it would have been protected until at most 1942.

Attached below is the little information I've found on this patent, an excerpt found in Google Books. If I'm interpreting this correctly, the below excerpt may show a license assignment to Roskopf. (From Patent-Liste: 1924, 1 - 24. Switzerland, Eidgenöss. Amt, 1924.)

Best wishes!

Don't know if Aegler 97101 was actually licensed but according to your clip, sure looks like it.

Thanks very much, Matthias.

Very interesting to see the centering post and three holes in the core specified in the patent.

Frey also licensed this patent in 1924.

Patents could not be renewed/extended, but the model deposits could. Ch97101 expired about Feb 15 1932. It’s expiry is listed in the March 7 1932 Swiss official register.
