IP Consultancy ByteLaw® provides an analysis (The Ghost in the Machine - A Deep Dive on Why The Meta Neuromuscular Patents Are Haunted by a Foundational EMG Predecessor) arguing that Meta Platforms' extensive portfolio of neuromuscular control patents for its augmented reality technology faces a critical legal obstacle from an older, foundational patent. This earlier patent, U.S. Patent No. 7,596,393 owned by ETRI, broadly claims the fundamental architecture of using wrist-worn EMG sensors to control a mobile communication device. The article demonstrates, using specific examples from Meta's patents, that Meta's advanced systems are merely improvements on this foundational invention, making them highly likely to infringe both literally and under the Doctrine of Equivalents. Because the foundational patent remains enforceable until 2028, the article concludes that securing a licensing agreement with ETRI is a commercial necessity for Meta to avoid the catastrophic risks of a sales injunction and massive willful infringement damages.
