Life Tech, ABI Drop Lawsuit against GenMark

By a GenomeWeb staff reporter

NEW YORK (GenomeWeb News) – GenMark on Thursday said that Life Technologies and its Applied Biosystems business had dropped its lawsuit against GenMark alleging patent infringement.

The lawsuit was filed on Nov. 19, 2010, and was dropped on Wednesday before GenMark could file a response, it said in a statement.

The suit alleged GenMark infringed on US Patent 6,514,699, entitled "Multiplex polynucleotide capture methods and compositions." According to its abstract, the patent covers technology "for simultaneously generating a plurality of polynucleotide sequencing ladders or PCR amplification products."

In its complaint, Life Tech and ABI alleged certain nucleic acid products from GenMark infringed on the patent, and in particular cited the example of GenMark's eSensor product, saying they "are specifically designed and used for the detection of nucleic acids that bind to immobilized capture probes."

GenMark didn't provide a reason why the suit was dropped.

In Thursday trade on the Nasdaq, shares of GenMark closed up 11 percent at $4.42.
