Hi! Josef here! I was just recently sharing a little update on socials, here is a copy:
Since I posted my “OHW is dead” article, you’ve been asking me about “that patent”. I didn’t want you to miss the forest (thousands of filings since 2020) just because of one tree. But let’s take a look now. In this case: the MMU multiplexer (we open sourced it 9 years ago). Anycubic (another IDG Capital-backed company) used the tactic of filing in China for an easy initial grant: CN 222407171 U > DE 20 2024 100 001 U1 > US 2025/0144881 A1. The playbook: file a Chinese utility model (10-year patent, same protections, lower examination, already granted) claim that priority in Germany (again as a utility model, already granted) file in the US. Cheap to file, but expensive and time-consuming to fight. I already wrote why prior art isn’t a magic wand that solves it immediately in my article ⤵ And there are many more, we just found a new juicy one!
Edit: Emojis stripped from the original, tried to fix it a bit ;-)
