How We Won: Promptu Counsel on Its $240M Victory Against Comcast

From a trusting relationship with the client’s in-house counsel, to exhaustive witness preparation, Finnegan reveals how they helped Promptu to protect its TV voice-recognition tech.

A near-decade-long dispute over TV voice‑recognition technology has finally concluded, with a $240 million payout for the winning party. In a decision handed down on January 23 in a Pennsylvania district court, the jury handed the victory to Silicon Valley start-up Promptu, finding that multinational media giant Comcast wilfully infringed two of its U.S. patents. Promptu, in collaboration with AgileTV, developed voice and speech recognition technology, based on natural language commands.

Promptu sued Comcast in December 2016, alleging that Comcast’s voice‑enabled TV products infringed Promptu’s voice‑recognition patents—namely, the AgileTV/Promptu voice-enabled remote and system, protected under its remote voice control patent, 7,260,538; and its remote voice response patent, 7,047,196. Comcast, however, was cleared of infringement on a third patent, RE44,326—“System and method of voice recognition near a wireline node of a network supporting cable television and/or video delivery”.

After an adverse claim‑construction ruling in 2022 led to stipulated non‑infringement to permit appeal, Promptu successfully appealed to the U.S. Court of Appeals for the Federal Circuit. The Federal Circuit vacated an earlier judgment and remanded the case after concluding that the district court had construed key claim terms too narrowly. This enabled Promptu—represented by Finnegan—to present its infringement case to a jury, which resulted in this recent favourable verdict.

Trial team lead at Finnegan Jacob Schroeder, and partner Jerry Ivey, tell World Intellectual Property Review (WIPR) the secrets of leading their client to this success.

WIPR: How did you come to represent Promtu in this case?
JS & JI: Finnegan first started working with Promptu in 2018, after the current district court case against Comcast was filed in late 2016. One year into the case, Comcast filed six inter partes review (IPR) proceedings, two of which covered business method review proceedings with the USPatent and Trademark Office (USPTO). Promptu sought Finnegan’s expertise in these proceedings. Comcast’s efforts failed, with the USPTO upholding the patents’ validity. Promptu subsequently retained Finnegan to take over lead responsibility for the district court litigation.

How did the strength of Promptu’s patent portfolio influence trial success?
As the patents describe, the problem—which pre-dated Promptu’s voice command technology—relied on expensive and powerful computers located in close proximity to the voice remote itself. What the Promptu inventors were able to accomplish was to remove the voice command processing from the user’s home for more efficient, centralised, remote processing, and the near-instantaneous return of programming and content to a wide population of users simultaneously.

What was it about your trial strategy that helped you to win?
Our success ties directly to our ability to satisfy the main question jurors often ask in patent cases, which is: who really was the first to develop the technology at issue? In this case, from the outset, Finnegan was able to explain, and during the trial demonstrate, that Promptu was indeed the first to successfully develop and first to patent the voice-enabled remote system for cable TV. We were able to provide an in-court tour of the voice-enabled remote and show a video from a 2004 demonstration of the technology in real time.

We were also able to play for the jury part of the Comcast CEO’s display and endorsement of Promptu’s technology on a national television program. During the trial, the Finnegan team provided an in-depth mapping of the patent claims to Comcast’s X1 technology [a cloud-based entertainment platform for pay-TV].

How did your relationship with Promptu’s in-house counsel contribute to this successful outcome?
Finnegan developed and maintains a close working relationship with the Promptu in-house counsel. Promptu, as a start-up company that developed foundational technology in the consumer electronics and media delivery space, faced a prolonged series of battles to protect its intellectual property from the larger Comcast entities. The long-standing relationship and trust among the firm’s partners and in-house counsel was essential to ensuring that Promptu had the legal and technological resources necessary to pursue this case to a successful conclusion.

What is the one takeaway from this case that you would like to share?
This case serves as a compelling illustration of the importance of developing an early case assessment that leads to a clear and accessible story for a jury to consider a trial. Finnegan assembled an extraordinary team of capable partners and associates who worked together to identify the key trial themes and to divide responsibilities among the team on both an issue-by-issue and witness-by-witness basis.

Witness preparation in this case was exhaustive. Extensive time and thought went into the preparation of illustrative aids, videos and demonstratives. Internal coordination and communication are essential in cases of this complexity. It was invaluable to the outcome that the team members were all committed to an unvarnished pressure-testing of themes and theories throughout the case, so that what the jury heard was a concise and compelling story that it could rely upon in returning its verdict.

The Finnegan trial team for Promptu was led by partner Jacob Schroeder, and included partners Jerry Ivey, John Williamson, Chris Blackford, Ben Schlesinger, Cara Regan, Jeff Totten, and Dan Klodowski.

The case is Promptu Systems Corporation v. Comcast Corporation et al., 2:16-cv-06516, US District Court for the Eastern District of Pennsylvania.
