@Stephanie_A Anyone can submit up to 3 examples of prior art for free with the USPTO. I covered the process on the OpenBeam blog.
It’s pretty typical that patents are typically drafted widely, either because the inventor didn’t know of the prior art or because the lawyer drafting the patent is trying to maximize the patent’s value, then narrow down over time based on prior art. So submitting prior art will help narrow the patent down to what’s genuinely an innovation by MBI.
I find Doctorow’s comments mostly insightful and on-point, but question what he means by “mostly open”. Mostly building on top of OS designs is not the same as mostly producing designs that are OS, which clearly MB is not.
