Shares of VeriChip Corp (CHIP.O) tripled after the company said it had been granted an exclusive license to two patents, which will help it to develop implantable virus detection systems in humans.

The patents, held by VeriChip partner Receptors LLC, relate to biosensors that can detect the H1N1 and other viruses, and biological threats such as methicillin-resistant Staphylococcus aureus, VeriChip said in a statement.

The technology will combine with VeriChip's implantable radio frequency identification devices to develop virus triage detection systems.

The triage system will provide multiple levels of identification -- the first will identify the agent as virus or non-virus, the second level will classify the virus and alert the user to the presence of pandemic threat viruses and the third level will identify the precise pathogen, VeriChip said in a white paper published May 7, 2009.
