the interesting patent isn't the rewrite, it's the map. microsoft's september 18 filing routes legacy code through an intermediate schema instead of one-shot translation, the step where most migrations die.
the artifact is the strategy.
Context
Patentlyze lists a Microsoft Technology Licensing application, US 2026/0277551 A1, filed March 12, 2025 and published September 17, 2026, with status docketed and ready for examination, and 20 claims. Its quoted claim has an AI system generate a schema that defines functional blocks of a legacy application and the logical relationships between them from the application and its documentation, then use the schema to convert the application.
This is a published pending application and not a granted patent. The note says September 18 filing, but the filing date shown is March 12, 2025, and September 18, 2026 is the aggregator page's update date. The claim text was read through Patentlyze and no USPTO or Google Patents page was located. The comparison to one-shot translation is Patentlyze's commentary. A similarly titled application on patents-review is Cognizant's, filed March 12, 2025 and published September 18, 2025, and is not Microsoft's. No shipped Microsoft product using the method was found.
Watch next
- The USPTO record, any office action, and a Microsoft product announcement.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
