Lorenz v. Berkline Corporation, 215 F. Supp. 869, 137 U.S.P.Q. (BNA) 29, 1963 U.S. Dist. LEXIS 10066 (N.D. Ill. 1963).

Opinion

CAMPBELL, Chief Judge.

This is an action for infringement of three patents brought by Anton Lorenz, an individual residing in Boynton Beach, Florida, against the Berkline Corporation, which was incorporated in the State of Tennessee and which has a showroom and sales office in Chicago, Illinois. Generally, the three patents relate to fixture or metal linkages embodied in reclining chairs. The defendant is engaged in the manufacture and sale of upholstered furniture, including reclining chairs. The plaintiff’s complaint alleges that he is the owner of the three patents in suit; the Lorenz Patent, No. 2,918,113; the Fletcher Patent, No. 2,940,509; and the Sehliephacke Patent, No. 2,940,510. The complaint further alleges that three chairs manufactured by defendant infringe the plaintiff’s patents. More specifically, it is alleged that defendant’s 87 T.Y. chair infringes all three of the patents in suit; that defendant’s Du-All chair infringes the Lorenz and Fletcher Patents; and that defendants Berkline 400 chair infringes the Lorenz and Fletcher Patents.

Defendant denies the validity of the patents and also that it has infringed them. Defendant has also filed a counterclaim seeking a declaratory judgment that the patents in suit are invalid and are not infringed by the defendant.

The Court having duly considered the pleadings, the evidence and briefs of counsel makes the following Findings of Fact and Conclusions of Law.

FINDINGS OF FACT

1. Plaintiff is the lawful owner of the patents in suit, to wit: the Lorenz Patent, No. 2,918,113, the Fletcher Patent, No. 2,940,509, and the Schlie-phacke Patent, No. 2,940,510. The Lorenz Patent was issued to the plaintiff on December 22, 1959. The Fletcher Patent was issued to the plaintiff on June 14, 1960. The Sehliephacke Patent was issued to the plaintiff on June 14, 1960.

DEFENDANT’S CHAIRS DO NOT INFRINGE PLAINTIFF’S PATENTS

2. Defendant’s 87 T V chair does not utilize any of the embodiments of the Lorenz Patent. Figs. 3, 4 and 5 of the Lorenz Patent has a seat and back-rest unit pivoted on a fixed single center, whereas the 87 T V chair pivots on two separate centers. The Figs. 3-5 embodiment of the Lorenz patent does not have a slotted guide member which is fixedly secured to a leg-rest link to move therewith, as does the 87 T V chair. The linkage arrangement in Figs. 3-5 embodiment of the Lorenz patent is different and functions differently from the 87 T V chair. The five embodiments of the Lorenz patent discloses that none of the Lorenz embodiments has a movable front guide link, or any guide link, which is slotted to cooperate with a pin. The Figs. 1 and 2 embodiment of the Lorenz patent has a stationary support with a slot 36 to receive a pin 34. The slotted support is not movable as is the member D of the 87 T V chair. The Lorenz patent has the leg-rest connected directly to the front of the seat, whereas in the 87 T V chair the leg-rest is connected and supported by a leg-rest linkage. The seat and back-rest unit in the Lorenz patent *871 (Figs. 1-2) pivots on a fixed single center, while the 87 T V chair pivots on two separate centers. The Figs. 6-8 embodiment of the Lorenz patent provides a seat and back-rest unit which also pivots on a single center. This Lorenz embodiment has no slotted guide link cooperating with a pin as does the 87 T V chair. The Figs. 9-10 embodiment of the Lorenz patent has no guide member which is slotted to cooperate with a pin, and it has no slotted member connected to the leg-rest linkage, as does the 87 T V chair. The Figs. 12-14 embodiment of the Lorenz patent has no guide member which is slotted to cooperate with a pin, and it does not have a slotted member connected to the leg-rest linkage as in the 87 T V chair. The 87 T V chair does not utilize the elements, or the combination of elements, and their functions, or their equivalents, as disclosed in the five embodiments and claimed in the Lorenz Patent.

3. The 87 T V chair does not utilize any of the embodiments of the Fletcher Patent. Each of the four embodiments of the Fletcher patent in suit discloses that none of the embodiments has a movable front guide link, or any guide link, which is slotted to cooperate with a pin. The Fig. 1 embodiment of the Fletcher patent has a member 22 which serves to connect the seat to the support, but this member does not have a slot or cooperating pin and it is not connected to a leg-rest linkage. The Fig. 3 embodiment of the Fletcher patent has a front member 122 and a rear member 123 which connects the seat to the support, however, neither of these members has any slots cooperating with any pins. The Fig. 5 embodiment of the Fletcher patent has a member 222 which serves to connect the seat to the support, but this member does not have a slot or cooperating pin and it is not connected to a leg-rest linkage. The Fig. 7 embodiment of the Fletcher patent has members fixed to the seat, which carry pins 333 and 335 which slide in slots 337-339 on the support. This embodiment does not have a slotted guide member D secured to a link which pivots with the movement of the leg-rest linkage, as in the 87 T V chair. The 87 T V chair does not utilize the elements, or the combination of elements and their functions, or their equivalents, as disclosed in the Fletcher embodiments and as claimed in the Fletcher Patent.

4. The 87 T V chair does not utilize the embodiment of the Schliephacke Patent. The front guide link D of the 87 T V fixture is fixedly secured to the link K, which is part of the leg-rest linkage. As the seat and back-rest unit is tilted, the front guide link pivots and operates the link K and leg-rest linkage. Although the Schliephacke patent embodiment has a front guide link 20, it is not connected in any way to the leg-rest linkage but is independent thereof. In the Schliephacke patent, the leg-rest is pivotally connected to the front of the seat by link 52 and a single link 56 operates the leg-rest. The leg-rest of the 87 T V is not connected to the seat, as in Schliephacke, but is connected to and supported by a plurality of links which operate the leg-rest. The arrangement and operation of the 87 T V bear no resemblance to the Schliephacke patent. The 87 T V chair does not utilize the elements, or the combination of elements and their functions, or their equivalents, as disclosed in the Schliephacke embodiment and as claimed in the Schliephacke Patent.

5. Each of the five embodiments of the Lorenz patent discloses that none of the Lorenz embodiments has a movable slotted member cooperating with a pin for permitting the seat and back-rest unit to move from intermediate to fully reclining position. The Figs. 1 and 2 embodiment of the Lorenz patent has a stationary support with a slot 36 to receive a pin 34. The slotted support is not movable as is the slotted member of the Du-All chair. The Lorenz patent has the leg-rest connected directly to the front of the seat, whereas in the Du-All chair the leg rest is connected and supported by a leg-rest linkage. The seat and backrest unit in the Lorenz patent (Figs. *872 1-2) pivots on a fixed single center,‘while the Du-All chair pivots on two separate centers. The Figs. 6-8 embodiment of the Lorenz patent provides a seat and back-rest unit which also pivots on a single center. This Lorenz embodiment has no slotted member cooperating with a pin, as does the Du-All chair. The Figs. 9-10 embodiment of the Lorenz patent has no slotted member which cooperates with a pin.
