Case Explained: 25-1371: NIELSEN COMPANY (US), LLC v. TVISION INSIGHTS, INC. [OPINION], Precedential

Court: United States Court of Appeals for the Federal Circuit Filed: 2026-08-14 The Federal Circuit affirmed the Patent Trial and Appeal Board’s (PTAB) final written decision holding that claims 4, 5, and 6 of U.S. Patent No. 11,470,243 were unpatentable as obvious under 35 U.S.C. § 103. The court rejected Nielsen’s arguments that the PTAB erred in finding the prior-art reference “Tian” to be analogous art and in concluding that Tian rendered the challenged claims obvious when combined with other references. Regarding the analogous art determination, the court applied a two-prong test: whether the reference is from the same field of endeavor or, if not, whether it is reasonably pertinent to the particular problem involved. The court reviewed the Board’s factual finding for substantial evidence. It held that the Board did not violate the Administrative Procedure Act by relying on the “reasonably pertinent” prong even though the petitioner primarily argued the “same field of endeavor” prong, noting that the theories overlap and the pertinence was implicit in the petition. Furthermore, the court clarified that the problem addressed by a patent is not limited to those expressly identified in the specification; rather, the Board properly identified the general problem of image processing and facial detection. The court found substantial evidence that Tian, which analyzed face resolution for expression analysis, logically would have commended itself to an inventor solving these problems. On the merits of obviousness, the court reviewed the Board’s factual findings for substantial evidence and its legal conclusion de novo. It rejected Nielsen’s contention that Tian failed to disclose the claim limitations regarding reducing image resolution and performing a two-step facial recognition process. The court determined that claim 4 does not require “binning” specifically, as it only requires reducing resolution, which Tian disclosed via down-sampling. Additionally, the claims do not limit the process to reducing only a first image or requiring full-resolution images for subsequent steps; thus, Tian’s teaching of detecting faces in a first frame and tracking them in subsequent frames satisfied the limitations of claims 4 through 6. Finally, the court found substantial evidence supporting the Board’s determination that there was a motivation to combine Tian with other references to save processing resources and time by performing face detection on reduced-resolution images. As a result of this affirmation, the PTAB’s decision finding the challenged claims unpatentable stands, meaning the patent rights for claims 4, 5, and 6 are invalidated, and Nielsen Company (US), LLC is precluded from enforcing these claims against TVision Insights, Inc.
