Life Tech Sues Bio-Rad for Infringing Protein-Production Patents

NEW YORK (GenomeWeb News) – Life Technologies has filed suit against Bio-Rad for allegedly infringing four patents that cover methods for protein production, according to court documents filed last week.

Life Technologies filed a complaint on Aug. 13 in the US District Court for the District of Delaware charging Bio-Rad with infringing four patents: US Patent Nos. 6,703,484; 7,223,566; 7,259,242; and 7,265,206. All four patents describe methods for producing polypeptides in bacterial host cells and are assigned to Life Technologies.

In the complaint, Life Tech claims that Bio-Rad's Precision Plus line of protein standards infringes one or more claims of the four patents. The allegedly infringing products include, but are not limited to, Bio-Rad's Precision Plus Dual Color Standards, Precision Plus Kaleidoscope Standards, and Precision Plus Protein WesternC Standards, according to the complaint.

The company is seeking a permanent injunction that will prevent Bio-Rad from marketing the products, triple damages because of Bio-Rad's "willful infringement," and attorneys' fees and other costs.
