Patent No. US11380985 (titled "Techniques For Pain Relief") was filed by Ncap Licensing Llc on Jul 6, 2020.
’985 is related to the field of pain relief, specifically addressing the need for effective, safe, and non-invasive techniques to mitigate pain without hindering the body's natural healing processes. Current methods often rely on pharmaceuticals or invasive procedures, which can have limitations, side effects, or interfere with the body's ability to heal.
The underlying idea behind ’985 is to leverage a reactive capacitance material to enhance the body's natural nerve impulse communication, particularly in the context of pain signals. Instead of blocking or distracting from pain signals, the invention aims to facilitate clearer reception of these signals by the brain, potentially enabling the brain to better assist in the body's healing processes.
The claims of ’985 focus on a patch comprising a first non-conductive outer layer, a reactive capacitance layer, and a second non-conductive outer layer. The reactive capacitance layer is encased and electrically isolated between the outer layers and is composed of conductive particles dispersed in a binder , with the majority of particles being adjacent but not touching each other. The claims also cover a method of using this patch by placing it either at the source of pain or between the pain source and the brain.
In practice, the patch is applied to the skin near the source of pain or along the nerve pathway leading to the brain. The capacitively coupled conductive particles within the reactive capacitance layer are believed to interact with the body's bioelectrical signals, enhancing nerve impulse communication. This enhanced communication allows the brain to more effectively process the pain signals and initiate appropriate healing responses.
The differentiation from prior approaches lies in the mechanism of action. Unlike TENS devices that introduce external electrical stimulation or pharmaceuticals that chemically interfere with nerve signals, this invention passively enhances the body's own communication pathways. The non-ohmic conduction and the specific arrangement of conductive particles within the binder are crucial for achieving this effect, creating a unique interaction with the body's bioelectrical field.
In the early 2010s when ’985 was filed, pain relief was typically achieved through pharmaceutical interventions or electrical stimulation devices. At a time when implantable medical devices commonly relied on established biocompatible materials and power sources, hardware or software constraints made non-invasive, passive pain relief solutions non-trivial.
The claims were rejected in a non-final office action. The rejection was based on nonstatutory double patenting over claims of U.S. Patent No. 10,707,570. The prosecution record does not describe the technical reasoning or specific claim changes that led to allowance.
This patent contains 23 claims, with independent claims 1 and 13. Independent claim 1 focuses on a method for using a pain relief patch, while independent claim 13 focuses on the pain relief patch itself. The dependent claims generally elaborate on the method and patch, adding details regarding the body type, reactive capacitance layer, flexibility, resistance, materials, additional layers, and attachment mechanisms.
