Transfer VISA from one employer to another employer with valid VISA stamping.

Hi Team,

I have a totally new H1B Stamped VISA which got selected on 2016 H1B lottery and valid till 30 September 2017. I never travel on this VISA.

I have switched from Company A to company B, so is that possible to transfer H1B VISA from company A to Company B?
If yes, then is there any time-frame?
If No, then company B need to file my new case for H1B lottery on coming year?

Thank you in advance for your reply.
