A patent has been filed and approved worldwide, which includes the United States. Now I would like to take this product, and ask Apple/Microsoft/Big vendors to see if they would be willing to integrate our product into their existing and future products, because we believe the product will truly change the way safety of electric/electrical devices are viewed. What is the best way to approach this? Should I start by cold-calling Apple/Microsoft/Big vendors? or send them a mail/email?
