Prior art

To identify the most relevant prior art for US patent 9173100, I will examine the patent's cited references. While a comprehensive prior art search would involve a broader scope, focusing on the citations directly listed in the patent provides insight into what the patent examiner and applicant considered relevant during prosecution.

A search for US patent 9173100 on the USPTO database can be performed using their Patent Public Search tool. This tool allows searching for patents and patent application publications by keywords or common fields like publication number.

Based on the publicly available information, including a Unified Patents contest seeking prior art for US9173100, the patent generally relates to vehicle ecosystems and on-board vehicle network security. The contest specifically targets claim 1 of US9173100-B2.

To provide the most relevant prior art, I need to access the full list of citations within the patent document itself. Without direct access to the full patent document's "References Cited" section, I cannot provide a definitive list of prior art and an analysis of which claims they potentially anticipate. However, the request specifically asks to "look at each patent citation for 9173100." As I cannot directly browse the USPTO database through this interface, I will outline the general process a patent analyst would follow.

Process for Identifying and Analyzing Prior Art (if full patent text with citations were available):

1. Obtain Full Patent Document: Access the full text of US9173100 from the USPTO Patent Public Search database.
2. Locate "References Cited" Section: Within the full patent document, find the section that lists "U.S. Patent Documents," "Foreign Patent Documents," and "Other Publications."
3. Extract Citation Information: For each cited patent, record:
   • Full Citation (Patent Number, Inventor, Issue Date)
   • Publication/Filing Date (Filing date is typically more relevant for 35 U.S.C. § 102 analysis).
   • Brief Description (This often requires reviewing the abstract and key figures/claims of the cited patent).
4. Analyze Potential Anticipation (35 U.S.C. § 102):
   • "Anticipates" Defined: Under 35 U.S.C. § 102, a claim is anticipated if every element of the claim is found, either explicitly or inherently, in a single piece of prior art.
   • Compare Elements: For each independent claim of US9173100 (Claims 1, 9, and 17), compare each element to the teachings of the cited prior art.
   • Focus on Independent Claims First: Independent claims broadly define the invention. If an independent claim is anticipated, its dependent claims are also generally anticipated.
   • Look for 1:1 Correspondence: Does the prior art disclose a "microprocessor executable network controller"? Does it disclose isolating "one or more other on board computational component(s) in a vehicular wireless network not affected by a security breach event from a computational component affected by the security breach event"?
   • Consider Dates: Ensure the publication/filing date of the prior art predates the priority date of US9173100 (November 16, 2011, as listed in the patent information).

Example of how a Prior Art entry would be presented (assuming hypothetical prior art):

U.S. Patent No. X,XXX,XXX (Example Patent)

• Full Citation: US X,XXX,XXX to Smith et al., issued MM/DD/YYYY.
• Publication/Filing Date: MM/DD/YYYY (Filing Date).
• Brief Description: This patent describes a vehicle communication system that uses a central gateway to manage data flow between different in-vehicle networks. It discusses methods for filtering unauthorized messages based on predefined rules.
• Potential Anticipated Claim(s):
  • Claim 1: The concept of a "network controller" and "isolating" components (element 1a and 1b) might be anticipated if Smith et al.'s central gateway performs similar isolation functions based on detected anomalies that could be considered a "security breach event." Further analysis would be needed to determine if the "vehicular wireless network" and "on board computational components" are explicitly or inherently present and if the isolation mechanisms (encryption, MAC filtering, etc.) are also disclosed.
  • Claim 9: Similar to Claim 1, the method steps of receiving warning signals and isolating components could be anticipated if Smith et al. details such a method.
  • Claim 17: The computer-readable medium containing instructions for such a system would also be anticipated if the functional aspects of the claim are met by Smith et al.

Without the actual list of cited prior art from the US9173100 patent, I cannot proceed with the specific analysis requested. However, the provided information indicates that Unified Patents has initiated contests to find prior art for US9173100, suggesting that identifying relevant prior art is an active area of interest for this patent.
