Portfolio overview

Suzhou Littelfuse OVS Co., Ltd. has been granted 18 US utility patents between 2021 and 2025, placing Suzhou Littelfuse OVS Co., Ltd. at rank #16,402 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in H01H (ELECTRIC SWITCHES; RELAYS; SELECTORS; EMERGENCY PROTECTIVE DEVICES). As a Foreign Corporation, Suzhou Littelfuse OVS Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.0/100 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 2021 through 2025, with 18 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. Suzhou Littelfuse OVS Co., Ltd.'s 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Suzhou Littelfuse OVS Co., Ltd. against peers pursuing similar technology classes.
