Original patent title: “Receiver device for facilitating wireless energy reception

Plain-English explanation by SahiLast reviewed · July 31, 2026

This patent describes a receiver device that wirelessly collects terahertz electromagnetic energy using special materials and an antenna, then converts it to electricity, but only after a transmitter authenticates it using a blockchain. Granted to Voice Life in 2021 with 22 claims, and it is expected to expire in 2040.

Coverage

What does this patent actually cover?

The patent describes a receiver device designed to get power without wires. It uses a special "receiver transceiver" (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1) that has an outer casing, called a "receiver enclosure," made with "metamaterial" (Claim 1). This enclosure is designed to catch and store "terahertz electromagnetic wave energy" (Claim 1) and turn it into regular electricity that can power other gadgets. The device's antenna, which helps it grab this energy, is made with "superconducting material" (Claim 1) for better efficiency. Before any power is sent, the receiver sends a "registration request" with a unique ID to a transmitter (Claim 1). The transmitter then checks this request against a "distributed block-chain" (Claim 1) to make sure the receiver is allowed to get power, and only then does it send the terahertz energy. For example, a smartphone with this receiver could request power from a nearby transmitter, which would verify the phone's identity on a blockchain before wirelessly charging it.

The gap

What does this patent NOT cover?

  • Does not cover wireless power transfer using frequency ranges other than terahertz electromagnetic waves.
  • Does not cover receiver devices that do not incorporate a metamaterial in their enclosure.
  • Does not cover receiver antennas that are not made with at least one superconducting material.
  • Does not cover wireless energy systems where the transmitter does not authenticate the receiver using a distributed blockchain.
  • Does not cover energy conversion systems that do not specifically store terahertz energy before converting it to electrical energy.
  • Does not cover wireless power systems that rely solely on near-field inductive or resonant coupling.

These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.

Market context

Who's building on this

Companies in this space

Voice Life, the assigneeassigneeThe entity that owns the patent — usually the inventor's employer or a company.Read more →, is actively developing wireless power solutions. Other companies in the broader wireless power space, such as Energous, Ossia, and Powercast, are also working on various forms of far-field wireless charging, though their specific implementations may differ in frequency or authentication methods.

Market impact

This patent describes a potential future for wireless power, moving beyond short-range inductive charging to longer-range, secure energy transfer. If implemented, such technology could enable a new generation of always-on, battery-free devices, potentially reducing reliance on charging cables and increasing the convenience of electronic devices. It could also spur the development of new secure power delivery standards.

Claim 1 — Plain English

What this patent covers

The patent describes a receiver device designed to get power without wires. It uses a special "receiver transceiver" (Claim 1) that has an outer casing, called a "receiver enclosure," made with "metamaterial" (Claim 1). This enclosure is designed to catch and store "terahertz electromagnetic wave energy" (Claim 1) and turn it into regular electricity that can power other gadgets. The device's antenna, which helps it grab this energy, is made with "superconducting material" (Claim 1) for better efficiency. Before any power is sent, the receiver sends a "registration request" with a unique ID to a transmitter (Claim 1). The transmitter then checks this request against a "distributed block-chain" (Claim 1) to make sure the receiver is allowed to get power, and only then does it send the terahertz energy. For example, a smartphone with this receiver could request power from a nearby transmitter, which would verify the phone's identity on a blockchain before wirelessly charging it.

The clever bit

The novelty lies in the specific combination of a receiver enclosure using metamaterials to efficiently capture and store terahertz electromagnetic energy, an antenna made of superconducting material for high efficiency, and a blockchain-based authentication system to ensure only authorized devices receive power. This creates a secure and highly efficient wireless power ecosystem.

What it does not cover
