`
`BACKGROUND OF THE RELEVANT TECHNOLOGY AND PRIOR ART
`
`
`Basic Wagon Design
`
`10.
`
`In the layperson’s parlance, most are familiar with wagons pulled by
`
`children or those used in yard work, and these have many features in
`
`common with wagons and trailers used in the agricultural industry. A
`
`wagon typically has an underlying frame with longitudinal frame members
`
`to which one or more axles are attached. For example, one axle is
`
`positioned near the front end, and one axle is positioned near the rear end,
`
`each axle typically having at least a pair of wheels. The front wheels are
`
`typically steerable. Because a wagon is generally pulled by a tow vehicle,
`
`the wagon includes an attachment structure such as a tongue, for example,
`
`which can be connected to and disconnected from the tow vehicle. The
`
`tongue is typically coupled to the front wheels so that the tongue’s side to
`
`side motion also moves the front wheels from side to side and thereby
`
`facilitates steering the wagon. Wagons are used to transport loads of
`
`materials via a bed, box, tank, etc. that is mounted to the upper side of the
`
`frame.
`
`11. As explained in the “Background of the Invention” section (“Background”)
`
`of the ‘504 patent: “Wagons are a traditionally and widely used form of
`
`transportation. Wagons are used to carry a wide variety of goods, including
`
`
`
`
`5
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`grains, livestock, dry goods, persons, liquids, machinery, etc.” (Ex. 1001 at
`
`col. 1, ll. 16-19). The Background of the ‘504 patent further explains:
`
`Wagons in their most basic form include a tongue, a
`frame, at least one pair of wheels, and a bed, box, or tank for
`hauling cargo. The tongue of the wagon may be connected to a
`vehicle, such as, for example, a tractor, truck, pickup harvester,
`or other self-propelled machine. A variety of wheels may be
`used, depending on the intended use.
`A common variation is the four-wheeled wagon, having
`pairs of wheels at either end of the wagon. The extra pair of
`wheels contribute [sic] to stability of the wagon and may also
`increase the load-carrying capacity. In a four-wheeled wagon,
`generally one pair of steerable wheels is capable of being
`pivoted in unison so that the wagon may be turned. The turning
`action is controlled by the tongue, which pivots the steerable
`wheels (i.e., the front wheels) by means of a steering rod or
`rods which connect the tongue to each steerable wheel. As the
`tongue is displaced to either side of a center position, both
`steerable wheels are therefore pivoted.
`In a conventional wagon construction, a frame is
`employed upon which the pairs of wheels are mounted. The
`tongue is pivotally attached to the front of the frame and
`connected to the steerable wheels through a steering linkage.
`The wheels and corresponding axles extend beyond the frame,
`but are positioned relatively near to the frame. This is because
`if the wheels extended far beyond the frame, excessive bending
`
`
`
`
`6
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`loads would be imposed on the axles, with possible breakage
`occurring as a result of heavy loads or due to traveling over
`rough roads or rough ground. Conventional wagon designs
`therefore have a frame positioned generally within about one-
`half of the wheel diameter from the wheel.
`(Ex. 1001 at col. 1, ll. 20-50).
`
`12.
`
`I will refer to these well-known and conventional wagons described in the
`
`Background of the ‘504 patent as “Admitted Prior Art Wagons.” Fig. 1 of
`
`the ‘504 patent depicts the undercarriage of one such Admitted Prior Art
`
`Wagon. (Ex. 1001 at col. 2, ll. 21-22, 34).
`
`13. Certain examples of conventional wagons that were on sale before the
`
`priority date of the ‘504 patent are shown in their respective trade
`
`publications. I have been informed that these trade publications will be
`
`submitted as Exhibits 1007-1012, and I have been asked to cite them as
`
`these Exhibits.
`
`14. First, “The Brent Grain Train” brochure was published in 1995 by

`
`Indentations in Longitudinal Frame Members
`
`20. The prior art at the time the ‘504 patent was filed also included several
`
`disclosures of vehicles, including towed vehicles, having longitudinal frame
`
`members with indentations that allowed for improved turning ability of the
`
`corresponding steerable wheels.
`
`21. As a first example, U.S. Patent No. 1,741,873 to Nordine2 (“Nordine”)
`
`issued December 31, 1929. (Ex. 1002). Nordine is directed to “a frame for
`
`trailers or the like which is provided with indentations in the sides thereof
`
`into which the front wheels may extend when turning on a short radius.”
`
`

`
`

`
`(Ex. 1002 at pg. 1, ll. 1-5; see also pg. 1, ll. 17-19). Nordine further
`
`explains:
`
`[Side] members 2 and 3 are bent inward to the points 8 and 9
`between the points 10 and 11. It is understood that these
`points may be positioned so that the frame will clear a wheel of
`any suitable design or size and the depth of the indentations
`may be greater or lesser as may be desired.
`(Ex. 1002 at pg. 1, ll. 74-80; see also pg. 2, ll. 64-66 (“the said side
`
`members provided with indentations to clear the wheels when making a
`
`turn.”)). The frame members with inwardly oriented indentations of
`
`Nordine are shown in Fig. 1, an annotated version of which is reproduced
`
`below.

`
`22. Second, U.S. Patent No. 2,373,398 to Hoobler3 (“Hoobler”) issued April 10,
`
`1945. (Ex. 1003). Hoobler is directed, in part, to a trailer vehicle for
`
`highway transport. (Ex. 1003 at pg. 1, left col., ll. 1-2). Hoobler discloses
`
`that “the channel frame 24 comprising the frame [20] is preferably curved
`
`or bent inwardly at both sides between the pivot pins 32 and 43, as
`
`indicated at 54, to allow sufficient room for turning of the dual wheels 47
`
`carrying the dolly frame 21.” (Ex. 1003 at pg. 3, left col., ll. 8-13). The
`
`frame 20 with inwardly oriented indentations of Hoobler are shown in Fig.
`
`8, an annotated version of which is reproduced below.

`
`23. Third, U.S. Patent No. 1,731,557 to Wright4 (“Wright”) issued January 23,
`
`1926. (Ex. 1004). Wright is directed to a highway vehicle. (Ex. 1004 at
`
`Title). Wright discloses: “The frame of the truck is bent inwardly as at 26
`
`and at 27 to accommodate the wheels 14 and 15 when the truck is turning
`
`relative to the frame 11.” (Ex. 1004 at pg. 1, ll. 90-93; see also claim 2).
`
`The frame members with inwardly oriented indentations of Wright are
`
`shown in Fig. 3, an annotated version of which is reproduced below.

`
`24. Fourth, German Patent Application Publication No. 3046054 to Gobel5
`
`(“Gobel”) was published on June 9, 1982. (Ex. 1005). Gobel is directed to
`
`an agricultural vehicle. (Ex. 1005 at pg. 2, ¶¶ 1, 2). Gobel discloses that
`
`“longitudinal carriers 2 are bent toward the vehicle center 13,” such that
`
`“the wheel on the inside of the curve engages into the bent the [sic] area of
`
`the carrier frame 15.” (Ex. 1005 at pg. 3, ¶ 2). Gobel explicitly refers to
`
`the bent areas of the longitudinal carriers as “frame indent[s]” and explains
`
`that the frame indents “create[] additional space for the locked front
`
`wheels” (Ex. 1005 at pg. 2, ¶ 6), such that “a small turning radius can be
`
`achieved.” (Ex. 1005 at pg. 2, ¶ 4). The frame with inwardly oriented
`
`indentations of Gobel is shown in Fig. 2, an annotated version of which is
`
`reproduced below.

`
`et al. (“Kataue”) was published June 8, 1985. (Ex. 1006). Kataue is
`
`directed to a body frame for a tractor. (Ex. 1006 at Title). Kataue discloses
`
`that a portion of the left and right frames (1) are “formed with a sufficiently

`
`narrow disposed spacing” therebetween so that “a steering turning angle of
`
`the front wheels (8)(8) that steer and turn near the narrow formed section
`
`can be sufficiently sharp.” (Ex. 1006 at pg. 2, ¶ 3; see also pg. 2, ¶ 1
`
`(“[T]he left and right frames preferably have a small cross section . . . in
`
`order to reduce the turning radius, a disposed spacing between the left and
`
`right frames is preferably as narrow as possible, and it is particularly
`
`preferred to be narrower in the area where a front wheel turns.”)). The
`
`narrowing of the left and frames results in inwardly oriented indentations in
`
`the frames, as shown in Fig. 2, an annotated version of which is reproduced
`
`below.

`
`SUMMARY OF THE ‘504 PATENT
`
`26. The ‘504 patent describes a short steer wagon having an improved turning
`
`capability. While the title of the ‘504 patent states that it is directed to a
`
`“wagon,” the disclosure of the ‘504 patent is actually limited to wagon
`
`undercarriages. For example, the claims and detailed description of the
`
`preferred embodiments do not discuss any container portion to be used on
`
`the claimed “wagons.” (See generally Ex. 1001). Moreover, the figures
`
`show only the undercarriage. (Ex. 1001 at Figs. 1-4.)
`
`27. The ‘504 patent teaches the basic structure and function of known,
`
`conventional wagons. (Ex. 1001 at col. 1, ll. 16-55; col. 2, ll. 34-38; Fig.
`
`1). As noted above, I will refer to these conventional wagons described in
`
`the Background of the ‘504 patent as “Admitted Prior Art Wagons.” In the
`
`Admitted Prior Art Wagons disclosed in the ‘504 patent, the turning radius
`
`is limited by contact between the steerable wheels and the longitudinal
`
`frame members. (Ex. 1001 at col. 1, ll. 52-54) (“The proximity of the frame
`
`limits the ability of the steerable wheels to pivot, and thereby limits the
`
`turning radius of the wagon.”). This interference point geometrically limits
`
`the maximum steering angle. Based on the prior art mentioned above, it
`
`was known for at least 70 years before the priority date of the ‘504 patent
`
`that improved turning capability could be achieved by indenting the
`
`
`
`
`20
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`longitudinal frame members so that the original interference point is
`
`displaced inwardly, thus permitting a greater turning angle and
`
`consequently a comparatively smaller minimum turning radius.
`
`28.
`
`It is clear that the indentations in the longitudinal frame members shown in
`
`Fig. 2 of the ‘504 patent are the sole inventive concept of the ‘504 patent.
`
`See the below comparison of Fig. 1 of the ‘504 patent, which shows an
`
`Admitted Prior Art Wagon (Ex. 1001 at col. 2, ll. 20-21, 34-37), and Fig. 2
`
`of the ‘504 patent, which shows an embodiment of the claimed invention
`
`(Ex. 1001 at col. 2, ll. 22-25).

`PROSECUTION HISTORY
`
`31. Application Serial No. 09/399,099 (“the ‘099 application”), which issued as
`
`the ‘504 patent, was filed on September 20, 1999, claiming priority to
`
`Provisional Application No. 60/101,950, which was filed on September 25,
`
`1998. (See Ex. 1001).
`
`32.
`
`I have reviewed the prosecution history of the ‘099 application. The
`
`Examiner allowed the ‘099 application without issuing an Office Action.
`
`(See Ex. 1012). A telephonic Examiner Interview was conducted on
`
`
`
`
`30
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`September 19, 2000, during which the Examiner and a representative for
`
`Applicant Unverferth discussed prior art reference GB 2,300,839 to
`
`Wheeler (“Wheeler”) and suggested claim amendments that were then
`
`reflected in an Examiner Amendment. (Ex. 1012 at 30). The Examiner
`
`Amendment to claim 1 consisted of the addition of the phrase “a frame
`
`having at least one longitudinal frame member,” amending “connected to a
`
`rear portion of a corresponding tongue for steering” to “connected to a rear
`
`portion of said tongue for steering with said tongue,” and amending “an
`
`intermediate portion of said longitudinal member” to “an intermediate
`
`portion of said longitudinal frame member.” (Ex. 1012 at 32; see also Ex.
`
`1012 at 18). Following the Examiner Interview, the Examiner issued a
`
`Notice of Allowability. (See Ex. 1012 at 31). As his Statement of Reasons
`
`for Allowance, the Examiner stated: “The limitation of a [sic]
`
`<<wheels…connected to a …tongue for steering with said tongue >> of
`
`lines 7 – 9, together with the remaining limitations in claim 1; has not been
`
`found in the art.” (Ex. 1012 at 32). The ‘504 patent issued on January 23,
`
`2001. (See Ex. 1001).
`
`33. None of the prior art discussed in my declaration was of record during
`
`prosecution of the ‘504 patent. It is my opinion that all of the references
`
`
`
`
`31
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`cited herein are more relevant and are stronger than the Wheeler reference
`
`that was discussed during the Examiner Interview.
`
`LEGAL PRINCIPLES
`
`34.
`
`I have been informed that a claim is anticipated when each and every
`
`element of the claim is found in a single prior art reference.
`
`35.
`
`I have been informed that, even if every element of a claim is not found
`
`explicitly or inherently in a single prior art reference, the claim may still be
`
`unpatentable if the differences between the claimed elements and the prior
`
`art are such that the subject matter as a whole would have been obvious at
`
`the time the invention was made to a person of ordinary skill in the
`
`art. That is, the invention may be obvious to a person of ordinary skill in
`
`the art when seen in light of one or more references.
`
`36.
`
`I have been informed that a person of ordinary skill in the art can be
`
`assumed to have before him/her all of the relevant prior art.
`
`37.
`
`I have been informed that a claim is obvious when it is only a combination
`
`of old and known elements, with no change in their respective functions,
`
`and that these familiar elements are combined according to known methods
`
`to obtain predictable results.
`
`38.
`
`I have further been informed that some examples of rationales that may
`
`support a conclusion of obviousness include:
`
`
`
`
`32
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
` Combining prior art elements according to known methods to yield
`
`predictable results;
`
` Simple substitution of one known element for another to obtain
`
`predictable results;
`
` Use of known techniques to improve similar devices (or products) in
`
`the same way (e.g., obvious design choices);
`
` Applying a known technique to a known device (or product) ready
`
`for improvement to yield predictable results;
`
` Choosing from a finite number of identified, predictable solutions,
`
`with a reasonable expectation of success—i.e., “obvious to try”;
`
` Known work in one field of endeavor may prompt variations of it for
`
`use in either the same field or a different one based on design
`
`incentives or other market forces if the variations are predictable to
`
`the person of ordinary skill in the art; and
`
` Some teaching, suggestion, or motivation in the prior art that would
`
`have led the person of ordinary skill in the art to modify the prior art
`
`reference or to combine prior art reference teachings to arrive at the
`
`claimed invention.
`
`39.
`
`I have also been informed that the rationale to combine prior art references
`
`can come from a variety of sources, not just the prior art itself or the
`
`
`
`
`33
`
`
`EXHIBIT 1014
`IPR Petition for U.S. Patent No. 6,176,504
`
`

`
`specific problem the patentee was trying to solve. And I understand that the
`
`references themselves need not provide a specific hint or suggestion of the
`
`alteration needed to arrive at the claimed invention; the analysis may
`
`include recourse to logic, judgment, and common sense available to the
`
`person of ordinary skill that does not necessarily require explanation in any
`
`reference.
`
`40.
`
`I have been informed that the following four factors are considered when
`
`determining whether a patent claim is obvious: (1) the scope and content of
`
`the prior art; (2) the differences between the prior art and the claim; (3) the
`
`level of ordinary skill in the art; and (4) secondary considerations tending to
`
`prove obviousness or nonobviousness.
`
`41.
`
`I have also been informed that the courts have established a collection of
`
`secondary factors of nonobviousness, which include: unexpected,
`
`surprising, or unusual results; prior art that teaches away from the alleged
`
`invention; substantially superior results; synergistic results; long-standing
`
`need; commercial success; and copying by others. I have further been
`
`informed that there must be a connection, or nexus, between these
`
`secondary factors and the scope of the claim language.
`
`
`
`

`
`
`EXHIBIT 1014

`
`

`
`42.
`
`I understand that an invalidity analysis requires first that the claims be
`
`construed. After the claims are construed, they are compared to the prior
`
`art.
`
`43.
`
`I have been advised by counsel that, absent any explicit teaching by the
`
`inventor, the ordinary and customary meanings of the terms in the patent
`
`are to be applied. Further, I have been informed that the application of the
`
`claim term should use the “broadest reasonable interpretation.”
`
`PERSON OF ORDINARY SKILL IN THE ART
`
`44. The ‘504 patent describes a straightforward modification of the longitudinal
`
`frame members of the Admitted Prior Art Wagons, consisting of adding
`
`indentations to longitudinal frame members to allow improved turning
`
`ability, such as decreased turning radiu
