Causam Enterprises shows up again and again in grid-management search results, and US20210376656A1, published December 2, 2021, is a representative specimen. Its claim 1 is not about power hardware at all — it is about managing grid elements over a network.
The CPC fingerprint makes the strategy plain. H02J 13/00006 and H02J 13/00026 are network supervision/control of power systems; H04L 67/10 is application-layer network services; H02J 3/14 is load control. The patent fences off the act of coordinating grid devices through messaging — telemetry up, commands down — which is the software spine of demand response and distributed-resource management.
Reading claim 1 as an examiner would: the limitation is the management system and its messaging architecture, not any physical device. That makes the claim broad in ambition and contentious in practice, because "manage devices over a network" has enormous prior art outside the energy domain. Causam's bet is that the energy-specific framing carries novelty.
The landscape point is that Causam has filed many such claims (the assignee recurs across grid-messaging searches with double-digit counts). That is a portfolio strategy: blanket the network/coordination layer of the grid with overlapping method claims and let breadth do the work. Whether the individual claims survive challenge is a separate question from the portfolio's deterrent value.
The discipline this desk insists on: a claim that grid management is a messaging problem does not equal owning the smart grid. It owns one framing, repeatedly asserted. The deterrent is the volume of overlapping filings, not the strength of any single independent claim — and that distinction is exactly what a defendant's counsel would attack.
