lseltzer writes "People in tech like to rant on patents specifically and generally and how stupid they are, but usually don't consider the actual rules followed by patent attorneys and the US PTO. An interview in BYTE with Andrew Schulman, a software patent litigation consultant, gives an intro on the reasoning employed by them. You may remember Schulman as the author of Undocumented DOS and other books which exposed undocumented APIs in Microsoft's products and their use of those APIs. He got a law degree and changed careers."
