`
`IN THE UNITED STATES DISTRICT COURT
`FOR THE DISTRICT OF DELAWARE
`
`
`WIRTGEN AMERICA, INC.,
`
`
`
`
`
`CATERPILLAR INC.,
`
`
`
`Plaintiff/Counterclaim-Defendant,
`
`v.
`
`
`
`
`
`
`C.A. No. 17-770-JDW
`
`
`
`Defendant/Counterclaim-Plaintiff.
`
`
`
`
`WIRTGEN AMERICA, INC.’S MOTION TO STRIKE
`CATERPILLAR INC.’S UNTIMELY NEW EXPERT OPINIONS
`
`Wirtgen America, Inc. (“Wirtgen”) respectfully moves to strike Caterpillar Inc.’s
`
`(“Caterpillar”) two new expert declarations attached to Caterpillar’s Motion Regarding Estoppel
`
`Defenses (D.I. 364) purporting to provide new expert opinions on issues that were never raised
`
`before in this case: D.I. 368 (Declaration of Richard W. Klopp) and D.I. 367 (Declaration of
`
`Andrew W. Smith). The opinions presented in these declarations were never disclosed in
`
`Caterpillar’s responses to interrogatories, not included in these experts’ reports, and not
`
`mentioned in the pretrial order. These new expert opinions are untimely and procedurally
`
`improper under Federal Rule of Civil Procedure 37(c)(1).
`
`Accordingly, Wirtgen moves the Court to strike them pursuant to Meyers v. Pennypack
`
`Woods Home Ownership Ass’n, 559 F.2d 894, 904–05 (3d Cir. 1977) for the reasons set forth in
`
`Wirtgen’s Brief in Opposition to Caterpillar’s Motion Regarding Equitable Defenses and
`
`Wirtgen’s Cross Motion to Strike.
