had H1b visa from Oct 2007 till Oct 2013. I left US in April 2011. Can I reuse my remaining period of visa now

Just to add more- currently I am on L1 visa in US since Oct 2012 and due to layoffs I might have to leave country. I have few employers who can sponsor my H1 visa but current years H1 cap is already full and I was thinking of using my previous H1B visa period. Please suggest any alternatives here.
Regards.

Hi Feroz, what did you find out? Can you use old h1b to work in the US now.
