Opinion

BARBARA M. G. LYNN, CHIEF JUDGE

*628Plaintiffs TNA Australia Pty Limited and TNA North America Inc. (collectively, "TNA") sued PPM Technologies, LLC ("PPM") for infringing U.S. Patent No. 7,185,754. On December 18, 2017, the Court held a claim construction hearing to determine the proper construction of disputed claim terms. Having reviewed the claims, specification, and submitted extrinsic evidence, and having considered the parties' arguments and the applicable law, the Court issues this Claim Construction Order.

I. Description of the Technology

Conveyors are used in a variety of industries. For example, the packaging industry uses conveyors to transport products within a factory. See '754 patent at 1:12-16. A common challenge is transferring a product from one conveyor to another. Typically, this is done through a system of "gates that are opened and closed and through which the product is removed from [one] conveyor and delivered to a further conveyor." Id. at 1:20-24. Using gates to transfer products has a number of disadvantages, such as cleaning issues. Id. at 1:35-36.

The '754 patent relates to a conveyor system that transfers a product from one conveyor to another without the use of gates. See '754 patent at 1:6-8. Figure 1 presents the preferred embodiment of the invention:

See id. at Fig. 1. The conveyor system includes two major components: conveyor segments 12 and transverse conveyors 11 . See id. at 2:41-54. Conveyor segments are placed end-to-end, along which a product is conveyed in the direction of the arrows 18 . See id. The transverse conveyors are positioned below the segments. See id. at 3:9-15. A conveyor segment rotates on a vertical shaft 14 , such that the downstream end of the conveyor segment moves in the general direction of the arcuate arrows 23 . Id. 3:1-8. That rotated segment is no longer aligned with the segment following it, so some of the products being conveyed fall down to the transverse conveyor. The magnitude of the misalignment can be used to control the quantity of products that are redirected to the transverse conveyor. Id. at 3:17-21.

Claim 1 is representative and provides a description of the various components, their relationships to each other, and their functionalities. All of the disputed terms are also present in Claim 1. It states:

A conveyor assembly including:

a first slip conveyor segment having a longitudinally extending conveyor surface upon which items to be conveyed are longitudinally transported, the segment having an upstream end and a *629downstream end , the upstream end being provided to receive said item;
a second slip conveyor segment, said second segment having a longitudinally extending conveyor surface upon which the items to be conveyed are longitudinally transported, the second segment having an upstream end and a downstream end, with said second segment being mounted relative to said first segment so that items leaving the first segment downstream end are delivered to the second segment upstream end ,
said segments being mounted to provide for lateral displacement between the first segment downstream end relative to the second segment upstream end from an aligned position at which a desired quantity of said items pass from said first segment to said second segment , and a displaced position at which a further desired quantity of said items is removed from said conveyor as a result of relative displacement between the first segment downstream end and the second segment upstream end ; and
a transverse conveyor positioned below said first segment downstream end and said second segment upstream end so that items leaving said first segment downstream end and not delivered to said second segment upstream end are delivered to said transverse conveyor.

'754 patent at 3:26-54 (emphasis added for the disputed terms).

II. Legal Standard

a. General Principles of Claim Construction

The construction of disputed claims is a question of law for the court. Markman v. Westview Instruments, Inc. , 52 F.3d 967, 971-72 (Fed. Cir. 1995), aff'd , 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996). "Ultimately, the interpretation to be given a term can only be determined and confirmed with a full understanding of what the inventors actually invented and intended to envelop with the claim." Phillips v. AWH Corp.
