This patent covers the mechanical design and operation of the dose setting assembly in drug delivery pens.

Pharmaceutical and medical device companies developing drug delivery systems should review this patent to assess potential freedom-to-operate implications. Competitors entering the pen injector market should evaluate whether their designs may infringe claims covered by this Sanofi patent. No immediate compliance actions are required as patents grant rights rather than impose regulatory obligations.
