Background

Nielsen owns U.S. Patent No. 11,470,243, which covers image-capture techniques used in audience-measurement systems. TVision sought inter partes review, relying in part on a publication by Ying-li Tian about facial analysis at different image resolutions. The Patent Trial and Appeal Board found the challenged claims obvious. Nielsen appealed, arguing that Tian was not analogous prior art and that the Board’s reliance on a reasonable-pertinence theory violated the Administrative Procedure Act.

This appeal concerns a different ruling from the parties’ earlier Delaware infringement trial, which LexSummary covered in its district-court verdict summary.

The Court’s Holding

The Federal Circuit affirmed. It held that the Board could consider whether Tian was reasonably pertinent even though TVision had emphasized the separate same-field-of-endeavor test. The evidence relevant to the two analogous-art tests overlapped, the petition implicitly placed reasonable pertinence in dispute, Nielsen actually addressed that issue, and Nielsen identified no prejudice from any alleged lack of notice.

Substantial evidence also supported treating Tian as analogous art. A patent may address more than the particular problem highlighted by its specification. Here, the claims, title, and specification showed that the patent addressed image processing and facial detection, not merely reducing illumination-source use. Tian studied facial analysis using low-resolution images and therefore would logically have drawn the attention of an inventor confronting those broader problems. The court also upheld the Board’s findings that the prior-art combinations taught the disputed limitations and supplied a motivation to combine them.

Key Takeaways

  • The problems relevant to analogous-art analysis are not confined to the problems a patent expressly identifies.
  • A petition may implicitly raise the reasonable-pertinence branch of analogous art when its evidence and combination analysis fairly put the patent owner on notice.
  • An APA notice objection requires prejudice; Nielsen had addressed reasonable pertinence and identified no additional evidence it would have offered.
  • Prior art aimed at facial detection in reduced-resolution images was reasonably pertinent to audience-measurement claims that analyzed camera images.

Why It Matters

The decision cautions patent owners against defining the inventor’s problem too narrowly when resisting analogous prior art. The Federal Circuit looked to the objective breadth of the claims and the patent’s overall disclosure, allowing art directed to a broader image-processing problem into the obviousness analysis. It also shows that overlapping analogous-art theories can survive an administrative-notice challenge when the record demonstrates a meaningful opportunity to respond.
