Marquip, Inc. v. Fosber America, Inc. And Fosber Spa, and United Container MacHinery Inc.Marquip, Inc. v. Fosber America, Inc. And Fosber Spa, and United Container MacHinery Inc.
On summаry judgment, the United States District Court for the Western District of Wisconsin ruled that defendants Fosber America, Inc., Fosber SpA, and United Container Machinery, Inc. did not infringe U.S. Patent No. 4,200,276 (the ’276 patent) under the doctrine of equivalents.
See Marquip, Inc. v. Fosber America, Inc.,
No. 96-C-726-S (W.D.Wis. Sept14, 1998) (order). The district court also denied Marquip, Inc.’s motion for relief under
I.
The ’276 patent claims a method and device for shingling and stacking corrugated paperboard sheets without interrupting the continuous flow of sheets. Because the corrugator runs continuously, it is difficult to remove completed stacks of sheets without interrupting the flow of the corru-gator. The invention solves this problem by creating a gap in the flow of sheets. The gap allows sufficient time to discharge a completed stack without interrupting the corrugator. Claims 9 and 13, the only two claims at issue, recite a method and a device, respeсtively, for automatically
9. In the method of conveying sheets in succession from a first location along a plurality of separate in-line conveyors to a stacker wherein a vertical stack of a predetermined number of sheets is to be formed, and wherein said plurality of conveyors are traveling at the same speed, the steps of:
(a) shingling said sheets as they pass said location to form a group of shingled sheets for stacking,
(b) increasing the speed of said group of shingled sheets,
(c) and slowing each said separate inline conveyor individually and secces-sively [sic] in a downstream direction in response to passage of the trailing end of said group past the end of each respective separate conveyor to thereby slow sheets traveling upstream of said group of sheets.
13. In a device for conveying sheets in suсcession from a first location along a plurality of separate in-line conveyors to a stacker wherein a vertical stack of a predetermined number of sheets is to be formed, and wherein said plurality of conveyors are traveling at the same speed, the combination comprising:
(a) means for shingling said sheets as they pass said location to form a group оf shingled sheets for stacking,
(b) means for increasing the speed of said group of shingled sheets,
(c) and means for slowing each said separate in-line conveyor individually and successively in a downstream direction in response to passage of the trailing end of said group past the end of each respective separate conveyor to thereby slow sheets traveling upstream of said group of sheets.
’276 patent, col. 7,ll. 22-39; col. 8,ll. 31-47 (emphasis added).
Marquip asserts that versions 1, 2, 3, and 4 of the Fosber device infringe claims 9 and 13 of the ’276 patent. Both parties rely on a stipulated description of the process in the accused Fosber devices. Version 2 is the most basic of the Fosber devices. In Version 2, a “shingling nip” continuously shingles or overlaps sheets onto a moving conveyor. The first convey- or moves the shingled sheets to a second conveyor, which moves at the same speed as the first. The Fosber device has an interrupt mechanism between the first and second conveyors. This mechanism grasps and holds some sheets to create a gap in the flow of sheets. Specifically, when the trailing end of the last sheet in a predetermined number of sheets (the preceding group) moves past the pinch point of the interrupt mechanism, the mechanism grabs and stops the next sheet. This action creates a gap and starts the next group of a predetermined number of sheets (the succeeding group).
At about the same time the interrupter grasps the first sheet in the next group, two other events also occur: (1) the second conveyor and аll other conveyors downstream of the interrupt mechanism speed up, carrying the preceding group toward a stacker at the end of the conveyors, and (2) the first conveyor slows down. When the preceding group leaves the third conveyor, the second conveyor slows again to the pace of the first conveyor and the interrupt mechanism releases the suсceeding group. Similarly, the third conveyor slows when the preceding group passes the fourth conveyor. The fourth conveyor slows when the preceding group is on a downstacker at the end of the conveyors. The downstacker discharges the preceding group from the stacker and makes room for a new stack.
Fosber’s Version 1 differs from Version 2 only in the location of the interrupt mechanism — namely midway along the second conveyor. When the interrupt mechanism closes, the interrupt mechanism itself moves at the same speed as the first conveyor. In Version 1, the second conveyor operates exactly the same as in Version 2, namely speeding up to widen
At the initial trial, the district court considered two of Marquip’s patents, the ’276 patent and U.S. Patent No. 4,273,-325. The district court granted summary judgment that Fosber did not infringe the two patents either literally or under the doctrine of equivalents.

No. 96-C-726-S (W.D.Wis. June 10, 1997) (order)
(Marquip I).
When Marquip appealed
Marquip I,
this court affirmed the district court’s grant of summary judgment that Fosber did not literally infringe the ’276 patent but vacated the summary judgment of non-infringement under the doctrine of equivаlents.
See Marquip, Inc. v. Fosber America, Inc.,
The critical issue in Marquip III was whether element (c) of claims' 9 and 13 covered the Fosber device. The district court concluded that the Fosber device performs the recited function оf slowing the conveyors and obtains the result of decreasing the speed of the sheets traveling upstream. See id. at 10. The district court determined, however, that the Fosber device performs the function “in a fundamentally different way.” Id. In particular, the district court held that “[t]he presence of a functional interrupt mechanism [in the Fosber device], not the minimal change in timing required by its presenсe, is that which makes defendants’ machines operate in a substantially different way” from the claimed inventions. Id. at 13. Marquip appeals.
In a separate appeal, Marquip appeals the district court’s refusal to set aside final judgment under
II.
This court reviews a district court’s grant of summary judgment without deference.
See Conroy v. Reebok Int’l, Ltd.,
To infringe under the doctrine of equivalents, the accused product must contain each claim element or its equivalent.
See Warner-Jenkinson Co. v. Hilton Davis Chem. Co., 520
U.S. 17, 40,
Based on the fundamental principle that no one deserves an exclusive right to technology already in the public domain, this court has consistently limited the doctrine of equivalents to prevent its application to ensnare prior art.
See Wilson Sporting Goods v. David Geoffrey &
Assoc.,
As a helpful illustration of the operation of this limitation on the doctrine of equivalents, this court visualized a hypothetical patent claim, sufficient in scope to cover literally the accused device.
See id.; Key Mfg. Group, Inc. v. Microdot, Inc.,
In this case, the district court found that the application of the doctrine of the equivalents to encompass Fosber’s device would ensnare technology in the prior art at the time of Marquip’s invention. Specifically, the district court found that the Vermes prior art patent, U.S. Patent No. 4,040,618, limits the range of permissible equivalents. Vermes teaches a sheet stacker with conveyor belts and an interrupt device. Specifically, Vermes discloses:
[T]he frictional interrupter bar 90 is the sole means used to interrupt the flow of sheets during the stack transfer cycle. The rubber pad of stop bar 90 frictionally engages the underside of the sheet passing over the gap between the two cоnveyors. Movement of the sheet is thereby stopped and at substantially the same time, conveyor IS shifts to high speed mode and conveyor 12 shifts to low speed mode. At high speed, belt 13 quickly transfers onto the stack those sheets downstream of the raised interrupter bar 90. In the meantime, the belt of conveyor 12 moving at low speed continues to receive sheets from the cor-rugator and advance them at about one-half normal speed, toward the bar 90. In this way, an excessive pile up of sheets behind the stop bar is avoided.
U.S. Patent No. 4,040,618, col. 9, 11. 19-35 (emphasis added). In other words, when the last sheet of the preceding group passes the interrupt mechanism, the Vermes interrupt mechanism engages and, at substantially the same time, the Vermes downstream cоnveyor accelerates and the upstream conveyor slows.
This description of the prior art Vermes technology describes with precision the operation of the Fosber accused device as well. When the processing circuitry of the Fosber device determines
Accordingly, it would be improper to interpret element (c) of the claims to cover the Fosber device by equivalencе because to do so would render the asserted claims unpatentable over the prior art.
See Wilson Sporting Goods,
Marquip’s arguments focusing on thе differences in sheet counting between Vermes and the ’276 patent is only marginally, if at all, relevant. Rather, the determinative factor in the infringement analysis turns on whether the slowing of the conveyors is in response to the passage of the trailing end, as the claims recite, or in response to the interrupt mechanism, as Vermes teaches and as the Fosber device operаtes. Marquip does not show any genuine disputes of material fact to satisfy its burden “to prove that the range of equivalents which it seeks would not ensnare the prior art.”
Wilson Sporting Goods,
Thus, the district court properly held as a matter of law that the Fosber device and method does not infringe under the doctrinе of equivalents because it uses technology — an interrupt mechanism and changing conveyor speeds — already in the prior art.
