The Nielsen Company (US), LLC v. TVision Insights, Inc.

Nielsen v. TVision Insights, decided August 14th, 2026. A precedential panel of the Federal Circuit, in an opinion by Judge Dyk, affirmed the Patent Trial and Appeal Board's decision that claims of a Nielsen audience-measurement patent were obvious. The court held that a reference can be analogous art because it is reasonably pertinent to the inventor's problem, and that the relevant problem is not limited to the one the specification expressly identifies. Here's the brief.

Nielsen's ’243 patent concerns audience measurement. A device uses a camera to capture images of people watching television, counts them by detecting heads and faces, and identifies them through facial recognition. The challenged claims recite reducing the resolution of an image and determining the orientation of a viewer's head from the reduced-resolution image.

TVision petitioned for inter partes review. Its grounds combined other references with Tian, a scientific paper evaluating how face resolution affects facial expression analysis. The petition argued that Tian was in the same field of endeavor as the patent.

The Board did not reach that theory. It found instead that Tian was reasonably pertinent to the problems the patent addressed, image processing and, particularly, facial detection and analysis, and it held the challenged claims unpatentable. Nielsen appealed. It argued that it lacked notice of the reasonable-pertinence theory, and that the patent's problem was narrower: the drawbacks of frequently activating a light source.

Whether a reference is analogous art is a question of fact, reviewed for substantial evidence. A reference is reasonably pertinent if, because of the matter it deals with, it logically would have commended itself to an inventor's attention in considering the problem.

The court first rejected the notice argument, for three independent reasons. The evidence for both prongs overlapped, and an analogous-art theory may be implicit in a petition. Nielsen had in fact addressed reasonable pertinence in its response. And Nielsen identified no argument or evidence it was prevented from presenting, so any error was harmless.

On the merits, the court rejected Nielsen's narrow framing of the problem.

The specification did describe the drawbacks of overusing a light source. But the challenged claims do not recite a light source at all.

Quoting the Supreme Court in KSR, the court explained that what matters is the objective reach of the claim. The patent itself supported the Board's identification of image processing and facial detection as the relevant problems. Its claims analyze camera images, and its title and background discuss image capture and facial recognition. Tian, which showed facial analysis succeeding on low-resolution images, shared that purpose.

The court also upheld the Board's findings that Tian taught the claimed resolution-reducing step, and that a skilled artisan would have been motivated to combine the references to save processing resources.

Nielsen v. TVision confirms that the reasonable-pertinence prong is measured against the problems the claims actually address, not only the problem the specification names. Consistent with KSR, a patent may be directed to several problems, and the objective reach of the claim controls. The decision also confirms that the Board may rely on the reasonable-pertinence prong when the petition implicitly put it in play.
