Portfolio overview

Ilumisys, Inc. has been granted 64 US utility patents between 2015 and 2022, placing Ilumisys, Inc. at rank #5,419 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in F21K (NON-ELECTRIC LIGHT SOURCES USING LUMINESCENCE; LIGHT SOURCES USING ELECTROCHEMILUMINESCENCE; LIGHT SOURCES USING CHARGES OF COMBUSTIBLE MATERIAL; LIGHT SOURCES USING SEMICONDUCTOR DEVICES AS LIGHT-GEN). As a US Corporation, Ilumisys, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, ilumisys sits between X-FAB Semiconductor Foundries Gmbh (64 patents, rank #5,415) and Abbvie Biotechnology Ltd. (63 patents, rank #5,423) - the closest US assignees by grant volume. The composite Innovation Score of 41.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 15 grants, compared with 49 in the 2015–2019 window, a -69% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Ilumisys, Inc.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ilumisys, Inc. against peers pursuing similar technology classes.
