The record first. Published September 28, 2023, US20230305615A1 (CPC H02J 7/0049 and G06F 1/3212), assigned to Intel. Named inventors include Udaya Natarajan and Kannappan Rajaraman. This is a published application. The method has a programmable adapter opportunistically negotiate charging based on device state — the kind of dynamic power negotiation that standards like USB-PD formalize.
Read the standards fight. Charging used to be proprietary and balkanized; regulatory and market pressure has pushed it toward common standards like USB-C and USB-PD. But within those standards, the negotiation behavior and certification still decide which accessories interoperate and which carry a premium. A platform player filing programmable-adapter IP is staking a position in that interoperability layer.
Follow the cash. The accessory market — chargers, docks, multi-port adapters — is large and margin-rich, and whoever shapes the negotiation protocol shapes who can build certified, interoperable accessories. Owning programmable-charging IP is a lever on that market, even within an ostensibly open standard.
Comparability discipline applies. "Fast charging" spans proprietary protocols and standardized negotiation; the business implications differ sharply. The publication pins this claim to programmable, standards-adjacent negotiation — useful for tracking who is positioning in the interoperability fight, and a reminder that a publication is a position, not a grant.
What the document does not disclose is the economics. It is a method application, not an accessory P&L. It will not tell you certification revenue, accessory margin, or licensing. It establishes a standards-adjacent position; the financial stakes are undisclosed.
For investors, the throughline is this: charging standardization moved the fight to the negotiation-and-certification layer, and the patent record shows which platform players are positioning to capture the accessory market within it.
