How do I contact ST Micro to find out if they are interested in our patent

I wish to send a document to PWM specialists at ST. How do I do that ?

Hello kenturrell.

Welcome to the DigiKey TechFoum.

I suggest you visit their website under About Us link and use the appropriate path from there. Seem you would be looking for the manufacturing side: Manufacturing at ST - STMicroelectronics

Hope that helps.

Many thanks Ken
