Life Technologies, the leading global biotechnology company, sued Affymetrix’s eBioscience. In the lawsuit filed on the last week of August, Life technologies claimed that eBioscience products, mainly eBioscience’s eFluor® Nanocrystals (but not limited to), have violated its three patents (8,071,3598,071,3608,071,361) on “Semiconductor nanocrystal probes for biological applications and process for making and using such probes”.

eFluor Nanocrystals are quantum dot flurophores containing a heavy metal core particle surrounded by a surface coating for attaching antibodies and other biomolecules.  The Nanocrystals has a number of advantages over conventional dyes, including multi-color, narrow emission spectra and highly photostable and bright. These properties make it useful in imaging.

eBioscience published a paper on semiconductor nanocrystals in June 2011 and launched two eFluor Nanocrystals kits in July 2011. Life Technologies’ patents were granted in December 2011, however one of the three patents was filed in as early as 2006. And this is the second time Life Technologies is suing eBioscience. Earlier in 2010, Life Technologies sued eBioscience for violating its three other patents.

eBioscience is a San Diego based company that just got acquired by Affymetrix in June. eBioscience founded in 1999 is a leading company for providing reagents, mainly immunology and oncology flow cytometry reagents.
