ACOMA Medical Industry Co., Ltd. — F0:0D:F5 (MA-L)

ACOMA Medical Industry Co., Ltd. holds a single IEEE MA-L block, F0:0D:F5, registered to the exact company name "ACOMA Medical Industry Co,. Ltd." at 2-14-14 Hongo, Bunkyo-ku, Tokyo, JP 113-0033. This is not a bare shell registration: the registrant resolves to an identifiable, long-established Japanese medical-device manufacturer founded in 1921, whose corporate address matches the OUI registrant address. ACOMA builds anesthesia machines and workstations, ventilators (e.g. the PRO-V mkII, ACOMA-1, and ART-21EX lines), electrosurgical units, suction units, and ultrasonic nebulizers, reports the leading domestic market share in Japan for anesthesia apparatus, and sells into 80-plus countries with roughly 160 employees. A single MA-L block is consistent with a specialist manufacturer that needs one 24-bit OUI for the embedded network interfaces on its monitoring and data-logging modules, rather than a high-volume consumer-hardware vendor. No source ties F0:0D:F5 to a specific named product or model, and no security advisory references the prefix, so device-level usage and security context remain unknown. Two data traps to avoid: IEEE publishes no assignment date for OUI blocks (a third-party "registered July 2, 2019" figure from an aggregator is a database artifact, not a fact), and unrelated "Acoma"/"Tacoma" street-address hits in the MA-S registry belong to different companies (Roboteq, Agar Corporation), not to ACOMA Medical.

IEEE assignment

F0:0D:F5 → "ACOMA Medical Industry Co,. Ltd." (name preserved verbatim from registry, including the unusual "Co,." punctuation) [Confirmed] — the IEEE MA-L registry (local IEEE MA-L snapshot)

MA-L (24-bit OUI); single block found for this vendor [Confirmed] — the IEEE MA-L registry

Registered address / country

2-14-14 Hongo, Bunkyo-ku, Tokyo, JP 113-0033 [Confirmed] — the IEEE MA-L registry

Company status / substance

active, identifiable Japanese medical-device manufacturer; corporate address matches the OUI registrant address exactly [Confirmed] — medical-xprt.com, healthmanagement.org, dnb.com, kompass.com

Founded

1921 [Likely] — medical-xprt.com/companies/acoma-medical-industry-co-ltd-117908, healthmanagement.org/site/p/acoma-medical-industry-co-ltd

Registration date

Unknown — IEEE publishes NO assignment/registration date for OUI blocks; a third-party "July 2, 2019" from maclookup.app is a database artifact, not an IEEE fact, and is NOT recorded [Confirmed] — no IEEE date exists; maclookup.app/macaddress/f00df5 (artifact, not used)

IANA reference

blank / not applicable — no IANA RFC reference exists for a vendor OUI assignment [Confirmed] — project convention

Device-level usage context

Unknown — no source documents which ACOMA product or model uses F0:0D:F5, or any in-the-wild sighting of the prefix [Unknown] — no source found

Security context

Unknown — no CVE, ICS-CERT/CISA advisory, or abuse/threat-intel report references ACOMA Medical or F0:0D:F5 [Unknown] — no source found

Data trap (do not confuse)

MA-S registry contains unrelated "Acoma"/"Tacoma" street-address hits belonging to Roboteq (7812 E Acoma Dr, Scottsdale AZ) and Agar Corporation (Tacoma Dr, Houston TX) — different companies, not additional ACOMA Medical assignments [Confirmed] — the IEEE MA-S registry
