Comment on Stratasys files patent infringement lawsuit against Bambu Lab

Linking the patents listed, because I’m struggling to understand what technologies are spelled out in them:
- 9421713- purge towers apparently
- 9592660- heated beds/ removable build plates
- 7555357- something to do slicing workflow/ path generation
- 9168698 / 10556381- detecting that force has been applied to the extruder
I’m taking my best guesses here, so feel free to correct me if I’m misreading something.

Thank you! Updated my comment with your links (The .gov site for the patent office is ironically difficult to permalink to, go figure)

They’re basically trying to patent troll because their company produces no more useful innovations.

I was more trying to armchair lawyer if they had a legitimate case here. Most of stuff they’re citing is used so broadly across the 3D printing community, I’m wondering if their patents are even enforceable anymore (as I understand IP law, if you don’t actively protect your IP you risk loosing it).
The whole thing almost reminds me of when Slice took Phaetus to court over the surgical pipe in the dragon hotend.

Patent law is not IP law. You don’t need to prove that you have defended your patent, the existence of the patent itself is “proof of ownership” and at any point during the patent’s life you can claim damages against an infringing company. The onus is then on the accused to prove that the claimed patent was invalid, not applicable, or filed incorrectly/in bad faith.
Yes, patent law is intentionally broken and very stupid.

It’s more that Bambulab has created an integrated 3D Printing Ecosystem with the mentioned patented features If you look at Prusa and other 3D Printer companies there are only very minor integrations that are not built in but more opt-in features
