How Google’s PageRank Patent Decided the Search Engine Wars

In 1998, Stanford PhD students Larry Page and Sergey Brin developed PageRank — an algorithm ranking web pages by the number and quality of links pointing to them. It solved keyword stuffing by measuring the web’s own structure. Key patent: US6,285,999 (Google Patents).

Stanford’s Equity Deal

Stanford received Google equity instead of cash royalties, yielding approximately $336 million when sold — a landmark in university technology transfer. The patent expired in 2017. By then, Google had built competitive advantages through 200+ ranking factors, machine learning, and user data that no single patent could represent. Patents buy time; what companies do with that time determines their long-term position.
