History

Historical Context

The early-2000s saw major antitrust actions against chip makers—Intel paid a €1.45 billion EU fine in May 2009 and a $25.4 million Korean fine in 2008—prompting firms to rely more on licensing revenue. Rambus’s 2026 royalty surge to $69.6 million reflects that shift, and Intel’s $1.25 billion settlement with AMD in November 2009 further underscored the trend.
