Helicos BioSciences Corp. reports that it has added two more defendants – Illumina Inc. and Life Technologies Corp. – to its lawsuit against Pacific BioSciences of California Inc. The suit now cites three companies for allegedly infringing on Helicos’ sequencing-by-synthesis patents, according to a Helicos press release.
The patents that the Cambridge genetics analysis technology firm have alleged infringement on are those using molecules that identify new nucleotides labeled on each DNA strand. Helicos noted in a news release today that its patents cover the process of neutralizing or removing of the label before adding a new nucleotide.
