Mike Silveri’s career invention record
At least 25 distinct U.S. patent grant numbers name Michael A. Silveri as an inventor or co-inventor. This verified selection spans 1991–2022 and includes earlier work outside Halogen Systems. It is a career record, not a claim that Halogen owns all of these patents.
Counted once per U.S. grant number. Published applications, international counterparts and the separately listed reissue US RE37055 are excluded. Related grants can belong to the same patent family, and some historical patents have expired or been reissued. Sources checked October 12, 2026.
