Hi, shr_salehi!

I'm sorry that no one has yet come along to address your question!

If you'd like to post a draft of your letter on this thread, I'm sure that there will be those of us who would be willing to come along to advise you as to how you might make improvements on it.

Thanks!

You need to register your patent , take your claims and define your unique selling features , find out what is that mean exclusive or a none exclusive licence and approach this potential relevant manufactures to give them the right to make use of your patented design with a very simple and cost effective mechanics
And relevant material selection for this design
