Ce11zDirect, Inc. and Invitr0gen Corporation (Ce11zDi-

the N0rthern District of I11inois. Celsis In Vitro, Inc.

CELSIS IN VITRO V. CELLZDIRECT 2
(Celsis) opposes. CellzDirect replies. Celsis moves to
strike CellzDirect’s reply CellzDirect opposes.
Celsis sued CellzDirect for infringement of its patent
related to methods of making and using multi-
cryopreserved hepatocytes. On Septernber 7, 2010, the
district court granted Celsis’ motion for a preliminary
injunction, finding that Celsis had established a likeli-
hood of success on the merits of its patent infringement
claim, that Celsis had shown it would be irreparably
injured absent the injunction, and that the balance of
hardships favored Celsis.
Cellzl)irect appeals the order granting the prelimi-
nary injunction and moves to stay the injunctioi1' pending
disposition of its appeal by this court. To obtain a stay,
pending appeal, a movant must establish a strong likeli-
hood of success on the merits or, failing that, nonetheless
demonstrate a substantial case on the merits provided that
the harm factors militate in its faVor. Hilton v. Braunskill,

, 778 (1987). ln deciding whether to grant a
stay, pending appeal, this court "assesses the movant's
chances of success on the merits and weighs the equities as
they affect the parties and the public." E. I. du Pon,t de
Nemours & C0. v. Phillips Petroleum Co., 

, 278
(Fed. Cir. 1987). See also Standard Hcwens Prods. u.
Gencor Indus., 

(Fed. Cir. 1990).
Based upon the papers submitted, and without preju-
dicing the ultimate disposition of this case by a merits
panel, we determine that CellzDirect has not established
the requisite likelihood of succeeding on the merits and
thus has not met its burden to obtain a stay, pending
appeal
Accordingly,
IT Is ORDERED THA'r:

3
CELSIS IN VITRO V. CELLZDIRECT
(1) Ce1lzDirect’s motion to stay the preliminary in-
junction is denied. This c0urt's temporary stay of the
injunction is lifted
(2) Celsis’ motion to strike is denied.
(3) Any other pending motions are moot.
