Neuralink hits a manufacturing milestone while a 1976 brain-interface patent goes unmentioned.
Neuralink reaches production scale while ignoring a patent from the year 1976.
Manufacturing breakthroughs for Neuralink receive significant media attention, yet Robert Malech described a wireless brain-computer interface powered by RF energy in US 3,951,134. This research received DARPA funding during an era when disco dominated music. The documented loop includes inductive power transfer through the skull, outward data telemetry, and stimulation, which mirrors the commercial system Neuralink released forty-eight years later.

A technical review highlights the specific claims. Claim 1 details an apparatus for monitoring brain waves using a transmitter, receiver, and power supply, which functions similarly to the N1 implant. Stimulation capabilities appear in Claim 7. Because the patent lapsed in 1996, these concepts have occupied the public domain for almost three decades. The actual progress achieved by Neuralink involves the hermetic packaging, the surgical robot, and the electrode density of 1,024 channels across 64 threads. These represent engineering milestones rather than original intellectual property.
The Malech design anticipated the power constraints of implants by using an external RF coil to couple through tissue rather than relying on a battery. Neuralink opted for an internal rechargeable cell to assist patient mobility, though this introduces potential thermal limits, recharge compliance, and battery degradation. Longevity remains the primary trade-off of the Malech approach. While modern components like thin-film capacitors, biocompatible ferrites, and gallium nitride rectifiers could improve this inductive scheme, the expired patent status leads many to treat the prior art as settled.
DARPA currently backs the N3 program, which explores magnetic, acoustic, and optical methods to bypass the need for physical implants. Neuralink focuses on the invasive version, and the company gained significant value by securing IDE approval, FDA Breakthrough Device designation, and first-in-human status. This regulatory path constitutes their primary moat instead of the underlying concept.
BCI development represents a fifty-year struggle rather than a recent innovation. Converting lab experiments into a medical device suitable for manufacturing justifies the credit Neuralink receives. Reviewing US 3,951,134 provides necessary context when others describe these systems as unprecedented, as the fundamental design was patented long ago.

That 1976 patent is a huge oversight—Malech’s wireless RF energy transfer design, which eliminated batteries entirely by coupling power inductively through the skull, already addressed the exact power challenge Neuralink now tackles with internal rechargeable cells. Who else spotted this during their BCI research? The core concept was public domain decades ago, so what Neuralink’s really pushing forward is engineering execution, not invention.
Those 1976 coil issues are terrifying—especially when you consider how Malech’s design solved the power problem entirely by relying on external RF coupling through the skull, a concept Neuralink now avoids with rechargeable cells. Did anyone else struggle with thermal runaway on early implants? The trade-offs between mobility and reliability are still playing out today.
The 1976 Malech patent already tackled the power challenge with an external RF coil design that couples through the skull—no batteries required—so it’s worth asking whether today’s noise floors could actually disrupt that inductive link over decades of use. Anyone benchmarked how modern interference (Wi-Fi, 5G, etc.) might degrade the signal integrity in a real-world scenario? The core concept still feels surprisingly relevant, even if Neuralink’s approach leans on rechargeable cells instead.
