This is about a bad patent that is preventing slicers from making brick-layer prints that would increase strength enormously, despite the fact that there is clear prior art that has expired for nearly a decade. The patent is full of bad references to the prior art and clearly shouldn’t have been approved - even if the person saying it isn’t a lawyer, it’s obvious.
The new bad patent from 2020 would keep the invention away for another 20 years, and do real harm to the development of 3d printing.
The creator asked viewers to share this with people in the FOSS slicer community. I don’t know if that’s anyone here, but lemmy is pretty FOSS-happy. Also the FOSS communities here might be interested to hear about how this patent is hamstringing development of FOSS features. I don’t have the time right now to search through the communities so any crossposts would be welcome.
„A specific technique on how to achieve it“, it usually a process patent. This can be circumvented and erases the protection. If the defined process is A>B>C>D and your process is A>E>C>D, then this does not touch the patent as it’s a different process.
