Hi Jenneke,
I found the design patent regarding the “gray egg” on google patents:
https://patents.google.com/
Searching for pre-1976 US design patents is a frustrating job. At least, you may find some on google, but only few. Obviously, google is using some kind of OCR technique making it possible to find some, but not all patents. The USPTO has - in principle - all design patents on its site, but you can find these pre-1976 patents there only by the number or by the US patent class. And that’s a sophisticated system, to say the least. Watch boxes can fall in US Patent class D03 or in D09, maybe in other classes, depending on the official who decided. Let’s take a look on D03 (“Carrier or Storage Container”):
https://www.uspto.gov/web/patents/classification/uspcd03/sch edd03.htm
The first Curvex box (US Design Patent No. 101,129) is in class D03/294 (“Enclosed - Hinged closure”), while the “gray egg” is classified in class D9/420:
https://www.uspto.gov/web/patents/classification/uspcd09/sch edd09.htm
As I said: sophisticated and if you don’t guess the matching class right, it’s next to impossible find the design patent you are after.
Well, I tried to find the “observatory” patent - without success.
Regards
Martin
