FullView, Inc. v. Polycom, Inc.

Background

FullView sued Polycom under 35 U.S.C. § 271 for infringing U.S. Patent No. 6,128,143, known as the ’143 patent. The patent concerns a panoramic viewing apparatus with multiple cameras, reflective facets arranged in a pyramid shape, and a support member. The motions before the court concerned independent claim 10 and dependent claims 11 and 12.

FullView alleged infringement by Polycom’s CX5000 Successor Products, including the CX5000 HD, CX5100, CX5500, CX8000 360°, and RealPresence Centro. The opinion’s infringement analysis focuses on the CX5000. The court had already construed “pyramid shaped element” to mean an object shaped like a pyramid, although its apex or base may be absent or incomplete. It construed “inner volume” as the space inside the area defined and bounded by the pyramid-shaped element.

Polycom previously challenged the ’143 patent’s validity in a petition for inter partes review, a process in which the Patent Trial and Appeal Board reviews patent validity. The Board denied institution after determining that the cited prior-art references did not anticipate or make the challenged claims obvious. In the district-court case, the court also denied Polycom’s motion for summary judgment of invalidity and granted FullView’s cross-motion for summary judgment of validity.

Summary-judgment standard

Under Federal Rule of Civil Procedure 56, summary judgment is appropriate when there is no genuine dispute about a fact that could affect the result and the moving party is entitled to judgment as a matter of law. For patent infringement, summary judgment is proper when no reasonable jury could find that every limitation of the properly interpreted claim is, or is not, present in the accused product, either literally or under the doctrine of equivalents.

Literal infringement

The court granted FullView summary judgment on infringement. Literal infringement occurs when the accused product contains every limitation of the asserted patent claim. The court examined the limitations of claim 10 individually.

First, the court held that the CX5000’s cameras are “image processing devices.” Claim 10 requires each such device to have one optical center and one field of view. Based on the claim language, the patent’s figures and description, and extrinsic evidence concerning how a person skilled in the field would understand the term, the court treated each camera as an image-processing device.

Second, the court held that the CX5000 contains a plurality, meaning more than one, of image-processing devices. Its five image sensors, lenses, and associated circuitry are equivalent to five cameras. The fact that the devices are mounted on one circuit board, or that later image processing occurs in a separate module, did not turn the five devices into one device.

Third, the court held that the CX5000 contains the required pyramid-shaped element. Its pyramidal mirror has a polygonal base, triangular sides, reflective facets facing in different directions, and cameras aimed in those directions. Polycom did not dispute this limitation.

Fourth, the court held that the cameras are “secured to” the support member. The cameras were attached through a sequence of components: the lenses were attached to image sensors, the sensors were soldered to a circuit board, the circuit board was screwed to a steel chassis, and the chassis was attached to the support member with a washer and nut. The court concluded that the patent did not require direct contact between the cameras and support member. Objects can be secured through intermediate fixed connections.

The court therefore concluded that the CX5000 embodies every limitation of claim 10 and that no genuine dispute of material fact prevented summary judgment of literal infringement.

Alternative infringement theory

The court also concluded that summary judgment was supported under the doctrine of equivalents. This doctrine can treat an accused product as infringing when a component performs substantially the same function, in substantially the same way, to achieve substantially the same result as the claimed component. The court applied that analysis to individual claim elements, focusing mainly on the “secured to” limitation.

The court found that both the patented arrangement and the CX5000’s arrangement provide consistent geometry and a rigid connection among the cameras, pyramid-shaped element, and support member. The intermediate structure did not substantially change how the cameras were secured, and the court noted Polycom’s concession that the securing method could be interchanged with the claimed method.

Sealing request and disposition

Polycom moved to file two exhibits to the Keller Declaration under seal. The court granted that motion because the exhibits contained proprietary, nonpublic circuit diagrams of components in the accused products and had been designated “Attorneys’ Eyes Only – Confidential.”

In FullView, Inc. v. Polycom, Inc., Judge Edward M. Chen granted FullView’s motion for summary judgment, denied Polycom’s motion for summary judgment, and granted Polycom’s motion to file the Keller Declaration Exhibits 1 and 2 under seal. The order disposed of Docket Nos. 190, 195, and 196 and set a further status conference for November 15, 2022.
