In the last two paragraphs it states that IBM used to publish papers on its inventions to prevent others from patenting them. I have heard that recently, the law has changed to allow it to be possible to patent something within a year of its publishing. Maybe someone knows more about this - is this true? Seems like it would incentivize patenting if so, rather than publishing or dedicating to the public, as then people would just patent whatever someone else publishes.
