Not a lawyer, but I think it should be pretty straightforward to prove that Stratasys is selectively /inequitably enforcing the patent given the prevalence of PEI build plates and automatic leveling, among other things, long before Bambu released a machine or became popular.
Bambu Lab was founded in 2020. Prusa, Creality and a whole bunch of other companies have been “violating” these patents long before Bambu even existed. Either this gets thrown out of court, or Stratasys will be able to sue quite literally every 3D printer manufacturer that exists for compensation.
Not to mention the patent for heated build platforms wasn’t filed for something like 4 years after the first heated bed was put to use. Stratasys only has the patent because that bought the company that filed it last year.
Also the heated bed was first put to use in 2010 as a way around the stratasys patent on heated build chambers, they never even thought to heat only the best.
Ah but there’s the rub. The lack there of of proof and logic is the exact reason Stratasys brought the suit to the Eastern district court of Texas. This is the same court where patent trolls go to win their fairy tale suits based on antiquated and overly broad patents that they purchased from long defunct companies. In the Eastern district court of Texas it’s not what you can prove it’s who do you know. Also known as corruption.
Truly amazing that the legal system in the rest of the US honors and enforces their edicts, or that anyone continues to do business within their jurisdiction, for that matter.
The companies that want to sue all have shell offices and PO boxes in east Texas.
It’s probably one of the main industries in some of the smaller towns. Tyler Texas I think maybe? It’s been a while since I first read about it.
