`PLAINTIFF WIRTGEN AMERICA, INC.’S FINAL INFRINGEMENT CONTENTIONS
`
`Pursuant to the Court’s July 23, 2021 Scheduling Order (D.I. 28) and Order Modifying
`
`the Scheduling Order (D.I. 159), Wirtgen America, Inc. (“Wirtgen America”) hereby provides
`
`the following Final Infringement Contentions concerning the infringement by Defendant
`
`Caterpillar Inc. (“Caterpillar”) of U.S. Patent No. 7,828,309 (“the ’309 patent”), U.S. Patent No.
`
`8,118,316 (“the ’316 patent”), U.S. Patent No. 7,530,641 (“the ’641 patent”), U.S. Patent No.
`
`8,113,592 (“the ’592 patent”), U.S. Patent No. 9,010,871 (“the ’871 patent”), U.S. Patent No.
`
`9,656,530 (“the ’530 patent”), U.S. Patent No. 7,946,788 (“the ’788 patent”), U.S. Patent No.
`
`8,511,932 (“the ’932 patent”), U.S. Patent No. 8,690,474 (“the ’474 patent”), U.S. Patent No.
`
`RE48,268 (“the RE268 patent”), U.S. Patent No. 8,424,972 (“the ’972 patent”), U.S. Patent No.
`
`9,879,390 (“the ’390 patent”), and U.S. Patent No. 9,879,391 (“the ’391 patent”) (collectively,
`
`“Asserted Patents”).
`
`I.
`
`Preliminary Statement
`
`Wirtgen America provides its Final Infringement Contentions subject to the following
`
`objections and reservation of rights:
`
`
`
`

`

`Case 1:17-cv-00770-JDW Document 383-10 Filed 05/10/24 Page 3 of 22 PageID #: 34947
`
`
`Wirtgen America has prepared these contentions based on information and discovery
`
`currently available. Fact discovery remains open and expert discovery has not yet begun in this
`
`case. Furthermore, Wirtgen America’s investigation into the infringement of the Asserted Patents
`
`is ongoing, especially since Caterpillar’s discovery production remains deficient. Based on
`
`current discovery, Caterpillar’s PM600 series milling machines (including the PM620 model and
`
`the PM622 model), the PM800 series milling machines (including the PM820 model, the PM822
`
`model, and the PM825 model), and the PM300 series milling machines (including the PM310
`
`model, the PM312 model, and the PM313 model) (collectively, “Accused Milling Machines”), as
`
`well as Caterpillar’s rotary mixers (including the RM600 model and RM800 model) (“Accused
`
`Rotary Mixers”) (the Accused Milling Machines and Accused Rotary Mixers collectively,
`
`“Accused Machines”), appear to infringe, both directly and indirectly, the asserted claims of the
`
`Asserted Patents, as detailed herein.
`
`Therefore, Wirtgen America reserves the right to supplement and/or amend these
`
`contentions as discovery in this case progresses or in light of any modification or clarification of
`
`Caterpillar’s non-infringement or invalidity contentions.
`
`These contentions are made pursuant to Federal Rule of Evidence 502 and the Protective
`
`Order (D.I. 61) entered in this case. To the extent that these contentions contain any information
`
`that may be protected from discovery under the attorney-client privilege, the work-product
`
`doctrine, the common-interest privilege, or any other applicable privilege or immunity, such
`
`disclosure is inadvertent and does not constitute a waiver of any such privilege or immunity.
`
`By submitting these contentions, Wirtgen America does not waive any claims or defenses
`
`that may be asserted in this case. These contentions may be asserted in the alternative and do not
`
`constitute any concession by Wirtgen America.

`
`Asserted Claims
`
`Wirtgen America contends that Caterpillar’s Accused Machines infringe, directly and
`
`indirectly, one or more of the Asserted Patents under 35 U.S.C. § 271(a) or (b) either literally or
`

`
`Because each of the four elevation cylinders is made from the samepart, the ride control feature causes the
`symmetrical displacement of each elevation cylinder in equal and opposite directions to the two immediately
`adjacent cylinders, producing a diamond-shapedstability pattern with vertices along the mid-points between each
`adjacent pair of cylinders. The widest transverse dimension ofthis diamond-shapedstability pattern (denoted by the
`dashedline below)is therefore along a transverse line mid-way between the front and rear elevation cylinders.
