Opinion

UNITED STATES DISTRICT COURT FOR THE DISTRICT OF NEW HAMPSHIRE

Presstek, Inc.

v. Case N o . 05-cv-65-PB Opinion N o . 2007 DNH 044

Creo, Inc. and Creo Americas, Inc.

MEMORANDUM AND ORDER

Creo, Inc. and Creo Americas, Inc. (collectively “Creo”)

have moved to strike supplemental expert disclosures filed by

Presstek, Inc. on the ground that they were filed after the

parties’ agreed-upon deadline for expert disclosures. Presstek

denies that the disclosures were late and alternatively claims

that they should not be stricken because it was justified in

making the disclosures when it did, Creo was not unfairly

prejudiced by the late disclosures and, in any event, a less

drastic sanction is all that is necessary under the

circumstances. I. BACKGROUND

A. The Infringement Claim

Presstek is the owner of U.S. Patent N o . 5,353,705 (filed

Sept. 2 2 , 1993) (“the ‘705 Patent”), entitled “Lithographic

Printing Members Having Secondary Ablation Layers For Use With

Laser Discharge Imaging Apparatus.” The ‘705 Patent discloses a

multilayer lithographic printing plate suitable for laser

imaging. The ‘705 Patent’s sole independent claim reads:

1 . A lithographic printing member directly imageable by laser discharge, the member comprising: a. a topmost first layer; and b . a second layer underlying the first layer, the second layer being characterized by ablative absorption of laser radiation; c. a third layer underlying the second layer, the third layer: i . being substantially transparent to the laser radiation; i i . being ablated only partially in response to ablation of the second layer; and iii. differing from the first layer in its affinity for at least one printing liquid selected from the group consisting of ink and a fluid that repels ink.

In the underlying patent infringement action, Presstek has

sued Creo, claiming Creo’s lithographic printing plate, the

Clarus W L , infringes the ‘705 Patent because it is comprised o f :

-2- (1) a topmost silicon layer, (2) an underlying second layer made

of carbon black/nitrocellulose which fully ablates1 during

imaging, and (3) an underlying third layer made of amorphous

Polyethlene Terephthalate (“PET”) which partially ablates in

response to heat generated during ablation of the carbon

black/nitrocellulose layer. The parties disagree as to whether

the Clarus WL has a third layer of amorphous PET and, if s o ,

whether the third layer partially ablates during the laser

imaging process.

B. Discovery Plan

A court-approved Amended Discovery Plan sets the deadlines

for expert disclosures in this case. (Doc. Nos. 1 9 , 5 4 ) . The

initial Discovery Plan includes a paragraph entitled “Dates Of

Disclosure of Experts And Experts’ Written Reports And

Supplementations.”2 (Doc. N o . 19 at 5 ) . The paragraph states

1 The ‘705 Patent defines “ablate” to mean “decomposes into gases and volatile fragments.” ‘705 Patent col.5 ll.16-19. 2 The caption is taken from Civil Form 2 , “Sample Discovery Plan,” which is appended to the Local Rules. The form calls for the specification of expert disclosure dates for plaintiffs and defendants as well as any agreed-upon dates for supplemental disclosures.

-3- The parties will exchange case-in-chief testifying expert reports on issues for which each party bears the burden of proof (e.g., patent infringement and damages for Plaintiff, patent invalidity for Defendants) on February 6, 2006. The parties will exchange rebuttal testifying expert reports on issues for which each party does not bear the burden of proof (e.g., patent validity for Plaintiff, patent non-infringement and damages for Defendants) on March 8 , 2006. Depositions of testifying experts will occur within the following 30 days.

The Magistrate Judge subsequently approved an Assented-To Motion

To Amend the Discovery Plan, which set September 1 5 , 2006 as the

date for the completion of discovery and extended the expert

disclosure dates to July 2 1 , 2006 for initial expert reports and

August 1 8 , 2006 for rebuttal expert reports. (Doc. N o . 5 4 ) .

C. Dr. Gido’s Initial Infringement Report

In accordance with the amended discovery plan, Presstek

disclosed a report prepared by its infringement expert, D r .

Samuel P. Gido, on July 2 1 , 2006. (Presstek Opposition to Motion

for Summ. J., Ex. 2 , Doc. N o . 60-4 (“Gido I ” ) ) . In preparing the

report, D r . Gido employed several different techniques to examine

both imaged and unimaged samples of the Clarus W L . Using

transmission electron microscopy (“TEM”) on an unimaged sample,

Dr. Gido concluded that the Clarus WL includes a topmost silicone

-4- layer and an underlying second layer of carbon

black/nitrocellulose, which together measure 0.5 microns thick.

Through selected area electron diffraction (“SAED”), he also

determined that the Clarus WL has a 6-7 micron thick layer of

amorphous PET between the carbon black/nitrocellulose layer and a

semi-crystalline PET substrate. D r . Gido also used scanning

electron microscopy (“SEM”) and atomic force microscopy (“AFM”)

on an imaged sample to measure the depth of the features that

result from imaging. Using SEM, D r . Gido obtained depth

measurements ranging from 1.3 to 2.0 microns, depending upon the

location sampled. Using AFM, D r . Gido obtained depth

measurements ranging from 1.2 to 1.8 microns. He then subtracted

his thickness measurement of the top two layers (0.5 microns)

from the combined range of depth measurements for imaged features

(1.2 to 2.0 microns) to determine that imaging produced features

that extend from 0.7 to 1.5 microns into the amorphous PET. Dr.

Gido then opined that imaging extended into the amorphous PET

because the amorphous PET partially ablated in response to heat

generated in the carbon black/nitrocellulose layer during its

ablation. D r . Gido did not perform any additional tests in an

effort to specifically demonstrate that PET gas molecules were

-5- released as a byproduct of the imaging process.

D. Creo’s Experts’ Rebuttal

On August 1 8 , 2006, Creo responded with rebuttal reports

from its experts, D r . Michael F. Rubner and Brian G. Eastman.

(Creo’s Assented-To Motion For Leave To File Sur-reply, Ex. 8 ,

Doc. N o . 74-11 (“Rubner Rebuttal”); Presstek’s Sur-reply to

Creo’s Motion for Summ. J., Ex. 9, Doc. N o . 76-6 (“Eastman

Rebuttal”)). They reported that the actual thickness of the top

two layers of the Clarus WL is at least 2 microns thick, rather

than 0.5 microns as reported by D r . Gido. D r . Gido’s

measurement, they opined, undermines his conclusion that imaging

extends into the amorphous PET. Furthermore, they claimed that

Dr. Gido had failed to offer any persuasive evidence that PET

removal results from ablation even if his depth measurements were

correct.

E. Deposition of Creo’s Expert, Dr. Rubner

On September 1 4 , 2006, Presstek’s counsel took D r . Rubner’s

deposition. (Creo’s Sur-reply to its Motion for Summ. J., Ex.

1 1 , Doc. N o . 104-17). Presstek’s counsel asked D r . Rubner

questions about two tests that D r . Gido had not conducted or

-6- included in his initial report but that, unbeknownst to Creo, he

would conduct the next day. First, Presstek’s counsel asked
