Across all tracked assignees
USPTO PatentsView assignee record - 8 granted patents across 5 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; SELECTION OF MATERIALS FOR THEIR MAGNETIC PROPERTIES).
The verdict
Chilisin holds 8 US patents across 5 technology areas, rank #31,152 of 50,000 tracked assignees.
Chilisin Electronics Corp. has been granted 8 US utility patents between 2022 and 2025, placing Chilisin Electronics Corp. at rank #31,152 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; SELECTION OF MATERIALS FOR THEIR MAGNETIC PROPERTIES). As a Foreign Corporation, Chilisin Electronics Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Chilisin sits between Charles Sturt University (8 patents, rank #31,148) and China National RICE Research Institute (8 patents, rank #31,156) - the closest US assignees by grant volume. The composite Innovation Score of 42.0/100 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. Historical data spans 2022 through 2025, with 8 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign 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. Chilisin Electronics Corp.'s 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chilisin Electronics Corp. against peers pursuing similar technology classes.

How to use this portfolio
Chilisin's 8 grants land it in the top 32% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
