When dealing with patents, public interest, and their consequences, Bell Labs should be treated separately imo. My vague recollection of the book The Idea Factory [1] and a brief search indicate that AT&T was always treated as a special case due to its status as a regulated monopoly. This status at least culminated in the 1956 Consent Decree [2], which required making all prior patents royalty-free and (as I read elsewhere) mandated that all future patents be licensed on reasonable terms. Given Bell Labs' well-known portfolio-including the transistor, laser, CCD, DSP, and fiber-optic-related patents, this shows a significant exception to how other companies might have innovated and monetized their innovations.
