The article mentions four patents:

9,168,698 / 10,556,381 - Force detection on the printhead, ie when your printer homes the z-axis by touching the nozzle against the build plate (would not include conductive or magnetic sensors)

9,421,713 - Using purge towers in prints with multiple filaments or extruders

7,555,357 - Not really sure exactly what this describes, so here is the patent's abstract:

A method of forming a three-dimensional object using an extrusion-based layered deposition system, the method comprising generating a build path for building a layer of the three-dimensional object, where the build path defines a void region. The method further comprising generating at least one intermediate path in the void region, and generating a remnant path based at least in part on the at least one intermediate path.

Seems to include slicing objects that are not completely solid on the surface (ie a cube with a hole through the center).

So, with this precedent, Stratasys can go after.. nearly every printer on the market. Cool

Yeah, stratsys supporters.

Hopefully bbl will appeal and win.

That article feels AI written.

What I find interesting here is that's a pretty small award. Barely as slap on the fingers. But it does throw the fear of god into other manufacturers.
