The most interesting thing about 2024 power-distribution IP is who is filing, not what. The distribution-control software layer is suddenly being claimed by entrants who historically sat out the patent game — and that shift is itself the story.
Regulated utilities are in. Duke Energy's US12068602B2 (advanced power distribution platform) is a regulated utility fencing software on its own grid operations — a rarity. Utilities buy equipment; they do not usually build patent walls. Duke doing so signals the distribution-control layer has become worth protecting.
Grid-software specialists are in. Utilidata's US20240213800A1 (smart grid distributed operations platform) and Apparent Labs' US11984722B2 ("virtual power grid") fence the orchestration software directly — these are companies whose entire value is the control layer.
And national labs continue seeding the foundation: UT-Battelle's US12095270B2 (distribution control) is public-research IP feeding the same neighborhood. Siemens' US20240402227A1 (grid criticality) shows the equipment incumbents are still filing too.
The strategic read: the distribution grid's value has migrated to software, and in 2024 every category of player — incumbent vendors, utilities, software startups, national labs — is filing to claim it. That is what a contested layer looks like. The caveat stands (one year, one CPC cluster, mixed publications and grants), but the entrant-diversity signal is robust and consistent across the data: distribution-grid software became a patent battleground in the mid-2020s, and the citation trails from these filings will show who is building on whom.
