Question on cap Exemption


My question is there in the heading itself
Company A filed a Petition for H1b on April 8, 2013 and Petition got approved in December 2013. But I never Travelled to US from them and left the company, then Company A revoked the petition in July 2015.

Now can company B file for H1 transfer under cap exemption based on my earlier H1B Petition.



Yes it can be done.No problems.
