This month, we are quizzing test takers on the history of diabetes. Our November 16th Question of the week quizzed test takers on the cost of the insulin patent. 74% of respondents, chose the best answer. We are excited to share this info with you in celebration of National Diabetes Month.

Before we start though, if you don’t want any spoilers and haven’t tried the question yet, you can answer below: Answer Question

Question:

On January 23rd, 1923, Dr.’s Banting, Best, and Collip were awarded the patent for insulin.

How much did Banting, Best, and Collip each charge the University of Toronto for their share of the insulin patent?

Answer Choices:

• They sold the patent for insulin for one million dollars to be divided by the 3 patent owners.
• They retained the patent for insulin to ensure exclusive rights.
• They sold the patent for insulin for $1 each.
• They sold the patent for insulin to pharmaceutical companies for an undisclosed amount.

As shown above, the most common choice was option 3, the second most common answer was option 2, then option 4, and finally option 1.

Price of the Insulin Patent

On January 23rd, 1923 Banting, Best, and Collip were awarded the American patents for insulin. They sold the patent to the University of Toronto for $1 each. Banting notably said: “Insulin does not belong to me, it belongs to the world.” His desire was for everyone who needed access to it to have it.

In order for the insulin to be mass-produced and widely available, the pharmaceutical company Eli Lilly and Co. were given the right to do so. Currently, Eli Lilly, Sanofi, and Novo Nordisk are the major insulin producers. Insulin is no longer extracted from beef and pork pancreases. Now companies use E. coli and yeast to produce insulin through recombinant DNA therapy.

With insulin patents expiring, we are now seeing the approval of biosimilar insulins that come with lower price tags. This lower-cost insulin keeps Dr. Banting’s dream alive, which is to make insulin a gift that belongs to the world.
