U.S. Court of Appeals for the Federal Circuit (CAFC) Cases

Two cases are listed in the patent text as filed in the Court of Appeals for the Federal Circuit in relation to US11208029. However, direct searches for these case numbers provided conflicting information.

  • Case Number: 25-1473

    • Jurisdiction: Court of Appeals for the Federal Circuit
    • Discrepancy Note: While the patent text lists this case as related to US11208029, a live search for "CAFC 25-1473" indicates a case titled "BURNS v. USA" filed on June 25, 2026, with an unreported opinion dismissing the case for lack of subject matter jurisdiction, and this search result does not mention patent 11208029. Therefore, the direct web search contradicts the patent's implication that this case is related to the patent.

    • Defendant(s): USA (as per external search results for the case number)

    • Status: No specific details regarding plaintiff(s), defendant(s), filing date, or outcome were found in the provided search results for this specific case number in relation to patent 11208029. The general search results for CAFC cases did not explicitly link this case to US11208029.
