Prior art

To identify the most relevant prior art for US Patent 7,924,802, I will use the USPTO's Patent Public Search tool.

Here's the approach:

1. Access the USPTO Patent Public Search database.
2. Search for patent number 7924802.
3. Locate the "Cited References" or "Prior Art" section within the patent document.
4. For each listed prior art reference, extract the full citation, publication/filing date, and a brief description.
5. Based on the description of US7924802's claims (provided in the prompt), I will then evaluate which specific claims each prior art reference potentially anticipates under 35 U.S.C. § 102.

(Self-correction): The initial search results provide general information about USPTO search tools and current litigation, but not the direct prior art citations for US7924802 from the USPTO database itself. I need to explicitly use the USPTO Patent Public Search to get the list of cited references. Since I cannot directly interact with a live search tool in this environment, I will proceed by stating how I would obtain this information and then provide a hypothetical example of how the analysis would be presented once that information is retrieved.

Hypothetical Prior Art Analysis for US Patent 7,924,802 (assuming retrieval from USPTO database):

If I were able to perform a live search on the USPTO Patent Public Search database for US patent 7,924,802, I would locate the "References Cited" section. For the purpose of this analysis, I will provide a structured example of how the most relevant prior art would be identified and presented, including how it might anticipate specific claims.

Example Prior Art Reference (Hypothetical):

• Full Citation: US 6,543,021 B1 to Smith et al.
• Publication/Filing Date: Published: April 1, 2003 (Filed: October 15, 2001)
• Brief Description: This patent describes a wireless communication system that transmits data using multiple carrier frequencies. It details a transmitter architecture where a single data stream is split, modulated onto two different carrier frequencies, amplified by separate power amplifiers, and then transmitted via separate antennas. The system aims to improve data throughput by utilizing parallel transmission paths.
• Potential Anticipation (35 U.S.C. § 102):
  • Claim 1: This reference potentially anticipates claim 1 because it describes transmitting "first information across a first frequency range" and "simultaneously transmitting second information across a second frequency range using the same wireless transmitter." While the hypothetical uses separate power amplifiers and antennas, the core concept of simultaneous transmission across different frequency ranges using a wireless transmitter is present. The specific limitation of "the same power amplifier" and "single antenna" in other claims might differentiate them.
  • Claim 6: If Smith et al. mention encoding the information using different protocols, this claim could also be anticipated.
  • Claim 8: If the "first information" and "second information" in Smith et al. originate from the "same data stream," this claim could be anticipated.

Explanation of Anticipation (35 U.S.C. § 102):

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 prior art reference. The analysis above demonstrates how a hypothetical prior art reference would be evaluated against the elements of specific claims from US 7,924,802. The presence of all elements in a single prior art reference, prior to the filing date of US 7,924,802 (January 23, 2008), would render the claim anticipated.
