In FullView v. Polycom, Judge Chen denied Polycom’s summary judgment motion, granted FullView’s, and denied FullView’s motion to strike over patent validity.
FullView obtained a ruling that claims 10 through 12 of its ’143 Patent were valid. Polycom’s invalidity motion was denied, and FullView’s motion to strike was also denied.
What happened
In FullView, Inc. v. Polycom, Inc., FullView alleged that Polycom infringed claims 10 through 12 of a patent covering panoramic imaging technology. Polycom asked the court to rule that the claims were invalid because they were obvious based on earlier publications. FullView asked the court to rule that the claims were valid.
The dispute focused on whether the earlier technology showed, or would have made obvious, a support member passing through the inside of a pyramid-shaped element. Polycom relied mainly on two Yamazawa publications and also argued that two other patents, called Iwerks and Goto, invalidated the claims. FullView also asked the court to strike parts of Polycom expert testimony referring to two other materials.
Judge Chen denied Polycom’s motion for summary judgment, granted FullView’s motion for summary judgment, and ruled that claims 10 through 12 were valid. The court also denied FullView’s motion to strike, finding that Polycom’s expert references to the additional materials did not violate the court’s earlier order.

Background
FullView sued Polycom for allegedly infringing U.S. Patent No. 6,128,143, which concerns devices that create panoramic images. The motions concerned independent claim 10 and dependent claims 11 and 12. Claim 10 requires, among other things, a support member that intersects the inside space of a pyramid-shaped element. Claim 11 requires image-processing devices to be secured to a portion of the support member extending beyond the pyramid-shaped element, and claim 12 requires the support member to be hollow.
Polycom moved for summary judgment—a ruling entered without a trial when there is no genuine dispute about a material fact—that claims 10 through 12 were invalid as obvious under patent law. FullView moved for summary judgment that those claims were valid. FullView also moved to strike references in a Polycom expert report to Nalwa 1996 and the UNC Device, arguing that those references violated an earlier order concerning Polycom’s invalidity contentions.
Polycom’s Invalidity Motion
The parties agreed on the definition of a person having ordinary skill in the relevant field and did not identify any disputed material facts. Their disagreement concerned the legal effect of the undisputed prior-art materials. Polycom relied on Yamazawa 1997 and Yamazawa 1998, which describe omnidirectional stereo imaging sensors.
The court held that Yamazawa did not disclose or suggest the required support member intersecting the inside of the pyramid-shaped element. The figures did not identify a support member or explain how the device was constructed. The court rejected Polycom’s expert’s conclusion that the diagrams showed one continuous support member as unsupported and conclusory. The court also found that an exterior photograph could not establish how the device was constructed internally, and that the cross-sectional diagrams did not show the claimed intersection.
The court further held that Polycom had not shown why a skilled person would have been motivated, at the relevant time, to modify Yamazawa to include the claimed intersection. Polycom identified possible benefits such as structural rigidity and a path for camera wires, but it did not provide evidence that these were known problems that would have prompted the modification. The court also rejected Polycom’s reliance on common sense to supply the missing claim limitation without supporting analysis or evidence.
Because Polycom did not prove obviousness by clear and convincing evidence, the court denied Polycom’s motion for summary judgment.
FullView’s Validity Motion
FullView also addressed the other prior-art references identified in Polycom’s earlier invalidity contentions: the Iwerks patent and the Goto patent. The court found no genuine factual dispute concerning either reference. Polycom disagreed with FullView’s legal analysis but did not identify conflicting evidence or provide analysis showing that either patent anticipated or rendered claims 10 through 12 obvious.
The court concluded that Iwerks depicted mirrored elements mounted on top of a cylindrical support rather than the claimed support-member arrangement. It also concluded that Goto depicted cameras mounted to a cone-shaped support, with separate mirrors inside the cameras, rather than cameras directed toward a pyramid-shaped mirror element. The court therefore held that Polycom had not shown by clear and convincing evidence that Iwerks or Goto invalidated the claims.
The court granted FullView’s motion for summary judgment, ruling that claims 10 through 12 of the ’143 Patent were valid.
Motion to Strike and Disposition
The court denied FullView’s motion to strike. It explained that its earlier order barred Polycom from adding Nalwa 1996 and the UNC Device as new invalidity grounds, but did not bar all references to those materials. Polycom used them to describe its expert’s background and the state of the art, not as new bases for its summary-judgment motion or amended invalidity contentions.
Judge Edward Chen’s order therefore denied Polycom’s motion for summary judgment, granted FullView’s motion for summary judgment, and denied FullView’s motion to strike. The order disposed of Docket Nos. 179 and 180.
