Opinion

BRYSON, Circuit Judge.

Honeywell Inc. is the owner of U.S. Patent No. 4,425,501 (“the ’501 patent”), which is entitled “Light Aperture for a Lenslet-Photodetector Array.” The patent claims an aperture mask for an autofo-cus system used in cameras and videocam-eras. Honeywell asserted the ’501 patent against Victor Company of Japan, Ltd., and U.S. JVC Corp. (collectively, “JVC”) in the United States District Court for the District of Minnesota. On JVC’s motion, the district court granted partial summary judgment, holding that JVC did not infringe the patent. In addition, the court ruled that certain imaging chips purchased by JVC from a subsidiary of Matsushita Electric Industrial Co., Ltd. (“MEI”), fell under the terms of an agreement licensing the ’501 patent to MEI and that Honeywell’s infringement claim against JVC could not succeed with respect to those chips. At the request of the parties, the court entered a judgment pursuant to Fed. R.Civ.P. 54(b) as to the claim of infringement and stayed further proceedings with respect to JVC’s counterclaim for a declaratory judgment of invalidity. We reverse in part, affirm in part, and remand.

I

An autofocus camera automatically adjusts the focus of its lens in order to obtain the sharpest possible photographic image. There are two main types of autofocus cameras. “Active” autofocus cameras operate by emitting either sound or light energy that is reflected off the object being photographed. That energy is then received back at the camera and processed in such a way as to determine the distance to the object and adjust the focus of the lens accordingly. “Passive” autofocus cameras, on the other hand, generate images of the object being photographed and determine whether the object is in focus based on the positions of the radiation patterns of the image on detector arrays within the camera.

The ’501 patent is directed to an improvement to a particular type of passive autofocus system that includes a set of small lenses, or lenslets, and a circuit chip containing light-sensitive detectors. During the operation of the system, light from a remote object is projected onto the detectors after first passing through the camera’s objective lens and the lenslets, which are embedded in a transparent member. Integrated circuitry coupled to the detectors then determines whether the image is in focus by comparing the light *1320 patterns appearing on the various detectors.

The ’501 patent explains that there are two problems with this type of autofocus system. First, because the member that includes the lenslets is transparent, light from the objective lens reaches not only the detectors, but also the adjacent circuit areas. Because certain circuit elements are sensitive to radiation in the visible range of the electromagnetic spectrum, allowing light to strike circuit elements may result in “spurious signals that can produce error in the circuit operation.” ’501 patent, col. 1, 11. 36-37. Second, surface defects in the transparent member can cause a scattering of light so that some light reaches the detector areas without first passing through the lenslets, causing erroneous readings by the detectors. We refer to these two problems as the “exposed circuit area problem” and the “surface imperfections problem,” respectively.

The improvement claimed in the ’501 patent is the use of an “opaque member,” or mask, to prevent the passage of some of the light coming from the object at which the camera is pointed. The mask is indicated by reference numeral 30 in Figure 1 of the ’501 patent shown below. Figure 1 also depicts transparent member 20, len-slets 21 and 22, circuit chip 10, and detector areas 11 and 12. Although not depicted in Figure 1, the detector areas are typically surrounded by circuit components. ’501 patent, col. 1,1. 67 to col. 2,1. 2.

The positioning of the mask in the embodiment of the invention shown in Figure 1 solves both the exposed circuit area problem and the surface imperfections problem because it ensures that light does not reach the exposed circuit area and that any light that passes through the transparent member passes only through the len-slets. Honeywell and JVC dispute whether claim 1 of the ’501 patent requires that the opaque member be positioned so that the device solves both problems or whether it is sufficient for the mask to be positioned to solve only the exposed circuit area problem. Claim 1, which has been reformatted for clarity, provides as follows:

1. Apparatus for use with an auto focus camera including
a circuit chip having a plurality of radiation responsive detector areas and a circuit area adjacent the detector areas which circuit area may produce error signals for the auto focus camera if exposed to light and including
a transparent member having a plurality of lenslets formed therein and placed contiguous the chip so that each lenslet directs radiation from a remote source onto one of the detector areas,
the improvement comprising:
*1322 an opaque member having a plurality of transparent portions therein placed contiguous the transparent member so as to permit radiation through the len-slets to reach the detector areas and to prevent radiation through the transparent member from reaching the circuit area.

Dependent claim 2 recites the apparatus of claim 1, in which the opaque member “has a plurality of holes therein corresponding to the plurality of lenslets.”

II

Honeywell brought this action against JVC, alleging that one of the components in JVC’s videocameras, known as a charge coupled device imaging chip, was covered by claims 1 and 2 of the ’501 patent. In response, JVC filed a motion for summary judgment of noninfringement, contending that its chips did not fall within the scope of those claims. In addition, JVC argued that some of the chips used in the accused products were sold to JVC by a supplier, MEI, that had licensed the ’501 patent from Honeywell, so that JVC was not liable for infringement based on its use of those chips. Honeywell filed a cross-motion for summary judgment on the latter ground, contending that the MEI chips were not covered by the Honeywell-MEI license agreement.

The district court first addressed the license defense and ruled in favor of JVC on that issue. Because JVC had purchased some imaging chips from suppliers other than MEI, however, that ruling did not entirely dispose of Honeywell’s infringement claim, but merely limited the number of accused devices to which the claim applied.

The court then addressed the question whether JVC’s remaining chips fell within the scope of the asserted claims. In addressing that issue, the district court construed the term “contiguous,” as used in claim 1, to mean “ ‘next in succession’ without any intervening structure.” As a result, the court ruled,
