Key Findings of "Measuring the Value of Invention" 

Economic Impact

  • The 26 Lemelson-MIT Prize winners were affiliated with more than 180 companies and institutions, founding more than 140 of them to develop or commercialize new inventions.
  • The independent companies founded by Prize winners that are still in operation and report financial data collectively employ approximately 40,000 people and generate total annual revenues exceeding $54 billion as of 2019.
  • Two companies founded by Prize winners were among the first biotechnology firms to achieve a market capitalization exceeding $100 billion. Several other publicly traded firms founded by winners had market valuations between $100 million and $50 billion as of 2020.
  • At least 35 of the companies affiliated with the winners were acquired or merged with other companies in deals valued at approximately $7.5 billion (in 2019 dollars).

    Economic Impact of Invention

Technological Impact 

  • The 26 winners held 3,871 patents for original inventions deemed to be “novel, non-obvious and useful” by the US Patent and Trademark Office (as of January 2020). 
  • The patents were cited as prior art by over 40,000 subsequent patent applicants, which demonstrates that they served as material inputs to future inventions by others.
  • 5,972 unique organizations were identified as having drawn on the winners’ original patents as they looked for citations for new patents.
  • The winner’s patents spanned a wide range of technological classifications, with the greatest number falling in the “medical or veterinary sciences and hygiene” innovation category. 


Scientific Impact

  • The 26 winners have published over 3,700 articles that have accumulated over 334,000 citations (as of March 2020). 
  • Winners’ articles were published in 682 different journals and were assigned 8,327 unique “Keyword Plus” keywords, demonstrating substantial breadth in the scientific content covered.
