Subsequent Events [Abstract]

Subsequent event, Description

the United States Patent and Trademark Office (“USPTO”) sent the Company an office action related to an ex parte reexamination of the Company’s 7,822,816 patent, which rejected all the claims in the patent (the “USPTO Office Action”). The Company has two months to file a request for the patent examiners to reconsider the USPTO Office Action. As a result of the USPTO Office Action, the Company has withdrawn all outstanding litigation relating the ‘816 patent without prejudice, which will allow it to refile such pending suits if the USPTO Office Action is rescinded or the Company’s rights under the ‘816 patent are restored.
