Obviousness

As a technical patent analyst, I am tasked with analyzing the obviousness of US patent 11924743 under 35 U.S.C. § 103, using the provided prior art references: US 2005/0288009 A1 (Kurosaki), US 2004/0046643 A1 (Hasegawa), and US 2008/0248810 A1 (Singh).

Inability to Retrieve Prior Art Content:
Despite multiple attempts to retrieve the full text of the cited prior art documents (US 2005/0288009 A1, US 2004/0046643 A1, and US 2008/0248810 A1) via Google Patents searches and direct URL attempts, the content of these specific patent publications could not be directly accessed or extracted from the search results. For US20080248810A1 (Singh), the Google Patents search explicitly indicated that the patent number could not be found. For US20050288009A1 (Kurosaki) and US20040046643A1 (Hasegawa), the search results provided snippets of other patents that merely cited these documents, rather than providing the full text of the documents themselves for analysis.

Conclusion on Obviousness Analysis:
Due to the inability to access the full content of the referenced prior art documents, I cannot perform a comprehensive obviousness analysis of US patent 11924743 under 35 U.S.C. § 103. Without the specific disclosures of Kurosaki, Hasegawa, and Singh, it is impossible to:

1. Identify how the elements of independent claims 1 and 8 of US11924743 are present in the individual prior art references.
2. Determine how combinations of these references would render the claims obvious.
3. Articulate a motivation for a Person Having Ordinary Skill in the Art (PHOSITA) to combine these references to arrive at the claimed invention.

Note on PTAB Challenges:
The previously generated "PTAB challenges" section indicates that these specific prior art references (Kurosaki, Hasegawa, and Singh) were indeed used by Google LLC and [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) in their IPR petitions (IPR2025-01349 and IPR2025-01237) against claims 1-14 of US11924743, alleging unpatentability under 35 U.S.C. § 103. [cite: https://portal.unifiedpatents.com/ptab/case/IPR2025-01349, https://portal.unifiedpatents.com/ptab/case/IPR2025-01237] However, both petitions were denied institution—one on discretionary grounds (Fintiv factors) and the other on the merits (failure to demonstrate a reasonable likelihood of prevailing). This suggests that the petitioners' arguments based on these prior art combinations were not deemed sufficient by the PTAB, but without the content of the prior art, a detailed technical assessment cannot be made here.
