Loeb & Loeb Obtains Claim Construction Victory for Celsis in Vitro in Patent Infringement Suit

Loeb & Loeb LLP secured a critical patent claim construction victory for client Celsis In Vitro, Inc. (Celsis IVT) in a case against CellzDirect Inc. and Invitrogen Corporation (now known as Life Technologies Corporation) for infringement of Celsis IVT’s LiverpoolTM patent (U.S. Patent No. 7,604,929). On November 26 Judge Milton Shadur of the U.S. District Court for the Northern District of Illinois agreed with Celsis IVT’s construction of all four disputed claim terms found in the asserted patent, which relates to methods for producing multi-cryopreserved hepatocyte cells.

Loeb & Loeb has represented Celsis IVT since the inception of this case, including obtaining a preliminary injunction against CellzDirect Inc. and Invitrogen Corporation, which was affirmed on appeal in January 2012.

Celsis IVT, a worldwide leader in life sciences products and services, is represented by a team of patent litigators from Loeb & Loeb’s Chicago office, including Adam G. Kelly.
