Meissen porcelain
The Blue Onion pattern (in fact copying Chinese pomegranates) has been in production for close to three centuries. It was effectively designed by Höroldt in 1739 and is probably inspired by a Chinese bowl from the Kangxi period. Widely popular, the pattern has been copied extensively by over sixty companies; some of those competitors have even used the word "Meissen" as a marking. But the pattern became so popular and widespread that the German Supreme Court in 1926 ruled that the "Meissen Zwiebelmuster" was in the public domain.
