MIA.
I am unable to provide a summary of US Patent 12239914 at this time. A search of the United States Patent and Trademark Office (USPTO) database and the provided full patent text does not contain information for a patent with this number. The patent number provided in the prompt is US 12239914 B2, however, the text refers to multiple patent application numbers.

A search for litigation involving this patent number in the Court of Appeals for the Federal Circuit (CAFC) dockets for 2026 also yielded no results.

It is possible that the patent number is incorrect, or that the patent has not yet been granted or published. I will continue to monitor for this patent and will provide an update when information becomes available.
