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.
How the hell was that even issued? Ianal obviously, my recollection from uni engineering was that Prior Art matters.
Also, given that there's a lot of skilled people in the field these days, you'd think some of these patents could be challenged as being "obvious to a skilled person", bed levelling to me could fit that bill given it's a common issue that would make sense to pursue a solution for. Granted I'm not versed in us patent law (I barely have a basic understanding of Canadian Patent Law), so maybe that's different.
