Prior art — US Patent 10523350

Prior Art Analysis for U.S. Patent No. 10,523,350

As a senior U.S. patent analyst, I have reviewed the prior art cited during the prosecution of U.S. Patent No. 10,523,350. Below is an analysis of each reference, detailing its content and its potential relevance to the claims of the '350 patent under 35 U.S.C. § 102 (Anticipation).

This analysis is based on the "References Cited" section of the issued patent and my interpretation of the claims. The '350 patent has a very early priority date of November 3, 1981, based on its parent application, US06/317,510. This early date is critical, as any prior art must have been published before this date to be considered anticipatory.

Cited U.S. Patent Documents

U.S. Patent No. 3,845,391: "Broadcast signal identification system" (Crosby)
- Publication Date: October 29, 1974
- Filing Date: June 18, 1973
- Brief Description: The Crosby patent discloses a system for identifying broadcast programs by embedding an inaudible identification code within the audio signal of the program. A monitoring device at a remote location can detect this code to verify program transmission. The primary purpose is for broadcast monitoring and verification for advertisers.
- Potential Anticipation Analysis: This reference teaches embedding an identification signal within a broadcast.
  - Claim 49: Potentially anticipates the concept of receiving a signal with an embedded instruction. Crosby's "identification code" could be interpreted as a form of "instruction" that directs the monitoring equipment to perform an operation (i.e., record the presence of the code).
  - Claim 112: Could be argued to anticipate this claim if the "identification code" is considered an "instruction" and the monitoring device is considered a "television receiver" performing an "operation" (logging the broadcast). However, the '350 patent's claims are generally directed toward personalizing content at the subscriber end, whereas Crosby is focused on broadcast verification.
U.S. Patent No. 4,025,851: "Automatic monitoring of television programs" (Haselwood et al.)
- Publication Date: May 24, 1977
- Filing Date: October 2, 1975
- Brief Description: Haselwood describes a system for automatically monitoring television programs to determine audience viewing habits. It involves embedding an identification code in the video signal (specifically, in the vertical blanking interval, or VBI) that is imperceptible to the viewer. A special monitoring unit at the television receiver detects this code and records which channel is being watched and when.
- Potential Anticipation Analysis: This is a significant prior art reference as it explicitly discloses embedding data in the VBI of a television signal to trigger an operation in a receiving unit.
  - Claim 49: This claim appears to be strongly anticipated by Haselwood. Haselwood teaches receiving a television signal with an instruction embedded in the vertical blanking interval (a non-viewable portion) that causes the receiver-side equipment to operate according to pre-programmed instructions (i.e., to record viewing data).
  - Claim 112: Haselwood also teaches a receiver being tuned to a channel, receiving an instruction (the identification code), and automatically performing an operation (recording the event).
  - Claims 1, 26, 80, 95, 102, 120: While Haselwood discloses the core mechanism of embedding instructions, it does not appear to describe the second key step in these claims: combining the broadcast programming with station-specific or user-specific information to create a personalized output. Haselwood's system is for monitoring, not for augmenting the displayed content with local data.
U.S. Patent No. 4,264,925: "Multi-channel television program simulation system" (Freeman et al.)
- Publication Date: April 28, 1981
- Filing Date: July 26, 1978
- Brief Description: Freeman discloses a system that allows a user to switch between different but related video streams broadcast simultaneously on multiple channels. For example, a user watching a sporting event could switch between different camera angles. The system provides a way for a user to interact with the broadcast to select from pre-determined, centrally-broadcast options.
- Potential Anticipation Analysis: This reference deals with user choice but not with the automatic combination of broadcast data with locally-stored, user-specific data.
  - No direct anticipation: Freeman's system relies on the user making a manual selection between multiple, fully-formed broadcast streams. It does not teach using an embedded instruction to automatically combine a primary broadcast with locally-generated, user-specific information as required by claims like 1, 26, 80, and 102.
U.S. Patent No. 4,337,480: "Dynamic interconnection system for television peripheral units" (Bourassin et al.)
- Publication Date: June 29, 1982
- Filing Date: February 28, 1980
- Brief Description: Bourassin describes a centralized switching system for managing various television peripherals (VCR, video game console, etc.). It allows for features like picture-in-picture, where a secondary image from one peripheral can be superimposed on the main image from another. The control is local to the user.
- Potential Anticipation Analysis: The '480 patent was filed before the '350 patent's priority date but published after. Under the pre-AIA "first-to-invent" system that applies here, it could be prior art if the invention date of Bourassin predates that of the '350 patent. Assuming it is valid prior art for the sake of analysis:
  - Claims 26, 95, 102: Bourassin teaches combining two video sources into a single display. However, it does not teach that this combination is triggered by an instruction embedded in the broadcast signal. The user manually controls the combination via the interconnection system. Therefore, it does not anticipate these claims, which require the combination to be initiated by a broadcast instruction.
U.S. Patent No. 4,381,522: "Interactive television program and distribution system" (Lambert)
- Publication Date: April 26, 1983
- Filing Date: October 24, 1980
- Brief Description: Lambert discloses an interactive cable TV system where a central computer generates a program schedule based on viewer requests sent over telephone lines. The system then automatically plays and transmits pre-recorded programs according to this schedule.
- Potential Anticipation Analysis: Like Bourassin, this patent was filed before the '350 priority date but published after. Assuming it qualifies as prior art:
  - No direct anticipation: The control mechanism in Lambert is a two-way system where users "pull" content by making requests. The '350 patent describes a one-way broadcast system that "pushes" instructions to the user's equipment to act on local information. Lambert's system does not involve embedding instructions in the broadcast signal to trigger a combination with user-specific data at the receiver.
U.S. Patent No. 4,547,804: "Multiplex television monitoring system and method" (Greenberg)
- Publication Date: October 15, 1985
- Filing Date: November 22, 1982
- Brief Description: Greenberg describes a system for monitoring multiple television channels by sequentially tuning to them and identifying embedded codes. It also includes the capability to monitor the audio and visual quality of the broadcast.
- Potential Anticipation Analysis: This patent was filed after the '350 patent's priority date and is therefore not prior art under 35 U.S.C. § 102. It was likely cited by the examiner to show the state of the art during prosecution.

Summary of Prior Art Analysis

The most relevant prior art cited against US 10,523,350 is U.S. Patent No. 4,025,851 to Haselwood et al. This reference clearly discloses the foundational concept of embedding machine-readable instruction codes into a non-viewable portion of a television signal (the VBI) to cause a receiver-side apparatus to perform a pre-programmed function automatically. This appears to anticipate the core ideas of independent claims 49 and 112.

However, Haselwood's system is for monitoring and data collection, not for creating a personalized media experience. It does not teach the key inventive step present in the other independent claims (1, 26, 63, 80, 95, 102, 120), which is the use of the embedded instruction to combine the broadcast program with locally-stored or locally-generated user-specific information to create a hybrid, personalized output for the user. The distinction lies in modifying the presented content for the user, rather than simply monitoring the user's activity. The other references, while related to interactive or enhanced television, also fail to disclose this specific combination of a broadcast-embedded instruction acting on local data for content personalization.
