#Stratasys uses 10 patents, two of them orginally from #Makerbot (anyone remember?) to sue #Bambulab in two separate US court cases. Patent infringement claimed on using a heated bed, using a purge tower, force detection etc. Seems Stratasys is patent trolling really hard ATM. https://www.tomshardware.com/3d-printing/3d-printer-maker-bambu-lab-faces-patent-infringement-lawsuits-that-could-threaten-hobbyist-3d-printing-in-general

3D printer maker Bambu Lab faces patent infringement lawsuits that could threaten hobbyist 3D printing in general

An OG in 3D printing is taking on a new, but highly successful, upstart in the industry

And before the panic sets in: These are *US* patent cases. Patent cases are *always* country specific. So until they (Stratasys) also file patent infringement cases in other countries, no need to worry, especially here in the EU (where I live).

The task of Bambulab (and hopefully also the #3dprinting community) is to collect so-called #PriorArt, showing that what was patented was already known and used before the patent was filed/granted. Especially in the case of a heated bed, which was filed in 2014, that seems to be quite easy to do.

When reading a patent, ignore everything but the claims and priority date. The claims are the core of the patent, everything else is description and blah-blah. The priority date is important for showing prior art. If you can prove that what the claims describe has been known *before* the priority date, that is a clear sign that the patent should be invalidated.
