Insights
Grant of a 40th U.S. patent strengthens Envoy Medical's IP base but supplies limited near-term commercial evidence.
The new U.S. Patent No. 12,485,288 covers proprietary methods for "Cochlear Implant Stimulation Calibration" that enable real‑time measurement and adjustment of electrical current from an implant stimulator to the auditory nerve. Strengthening the patent portfolio to 40 U.S. patents and 45 foreign patents increases the company's legal protections around core technology and can raise barriers to simple copycat entrants.
Key dependencies and risks remain: the announcement does not disclose licensing, enforcement strategy, or any financial terms, and a patent alone does not change regulatory or clinical outcomes. The release notes that the Acclaim cochlear implant has Breakthrough Device Designation and is under a U.S. pivotal clinical trial, but no trial endpoints or results are reported here, so near‑term commercial impact is uncertain.
Watch for concrete, monitorable items over the next 6–24 months: published pivotal trial endpoints and enrollment milestones, any patent claims asserted or licensed, and issuance of additional patents or foreign grants. Those items will better indicate whether the patent portfolio translates into defensible market position or measurable commercial value.

About Envoy Medical, Inc.
Envoy Medical (NASDAQ: COCH) is a hearing health company focused on providing innovative technologies across the hearing loss spectrum. Envoy Medical has pioneered one-of-a-kind, fully implanted devices for hearing loss, including its fully implanted Esteem® active middle ear implant, commercially available in the U.S. since 2010, and the fully implanted Acclaim® cochlear implant, an investigational device. Envoy Medical is dedicated to pushing hearing technology beyond the status quo to improve access, usability, compliance, and ultimately quality of life.
About the Fully Implanted Acclaim® Cochlear Implant
We believe the fully implanted Acclaim Cochlear Implant ("Acclaim CI") is a first-of-its-kind hearing device. Envoy Medical's fully implanted technology includes a sensor designed to leverage the natural anatomy of the ear instead of a microphone to capture sound.
The Acclaim CI is designed to address severe to profound sensorineural hearing loss that is not adequately addressed by hearing aids. The Acclaim CI is expected to be indicated for adults who have been deemed adequate candidates by a qualified physician.
The Acclaim Cochlear Implant received the Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA) in 2019.
CAUTION The fully implanted Acclaim Cochlear Implant is an investigational device. Limited by Federal (or United States) law to investigational use.
About the Esteem® Fully Implanted Active Middle Ear Implant (FI-AMEI)
The Esteem fully implanted active middle ear implant (FI-AMEI) is the only FDA-approved, fully implanted* hearing device for adults diagnosed with moderate to severe sensorineural hearing loss allowing for 24/7 hearing capability using the ear's natural anatomy. The Esteem FI-AMEI hearing implant is invisible and requires no externally worn components and nothing is placed in the ear canal for it to function. Unlike hearing aids, you never put it on or take it off. You can't lose it. You don't clean it. The Esteem FI-AMEI hearing implant offers true 24/7 hearing.
*Once activated, the external Esteem FI-AMEI Personal Programmer is not required for daily use.
Important safety information for the Esteem FI-AMEI can be found at: https://www.envoymedical.com/safety-information.
