Verdict
Operating-company assertion (current assignee ships products embodying the claims and is suing actual competitors)
The patent is currently assigned to Neurent Medical Ltd., an operating company that develops and markets medical devices for nasal treatment. The only other recorded event is a security interest with a lending institution, which is a common operating-company financing activity. There are no signals of shell entities, known asserters, or other NPE patterns.
