Perhaps Prodigy finally has a net-positive ROI -- earlier in the article: "IBM lawyer John Desmarais told a jury in federal court in Delaware that Groupon infringed patents describing foundational e-commerce technology that had already been licensed to Amazon Inc, Facebook Inc and Alphabet Inc’s Google for between $20 million and $50 million per company."
"Two of the four patents at issue relate to Prodigy, a late-1980s forerunner to the internet, developed by IBM and others, that describe a system for showing applications and advertisements that reduces server loads.IBM seeks $167 million from Groupon in dispute over early internet patents -- Reuters
IBM also said it patented so-called “single sign on” technology that allows consumers to log in to a retailer’s website with their Facebook or Google account.
Desmarais told jurors IBM is a prolific innovator and seeks to license its patents on reasonable terms. IBM had no choice but to sue Groupon after it refused to negotiate a licensing deal, he said."
