The Federal Circuit rejects Bruker Cellular's invalidity challenge to AbCellera's patent for microfluidic devices and their use in culturing cells

AbCellera (NASDAQ:ABCL) today announced that the United States Court of Appeals for the Federal Circuit (CAFC) has by a Rule 36 Order affirmed judgment of validity of its U.S. Patent No. 10,087,408 ("the ‘408 Patent"). AbCellera's ‘408 Patent is directed to microfluidic devices and using such devices to culture and selectively recover cells.

Previously Berkeley Lights Inc., now Bruker Cellular Analysis, Inc. (Bruker), a subsidiary of Bruker Corporation, challenged the claims of the ‘408 Patent alleging invalidity based on anticipation and obviousness over the prior art. The U.S. Patent Trial and Appeal Board (PTAB) rejected all of Bruker's arguments and now the CAFC has confirmed that all claims of AbCellera's ‘408 Patent are valid. AbCellera's ‘408 Patent is part of a multi-patent infringement litigation between AbCellera and Bruker pending in the U.S. District Court for the Northern District of California.
