Portfolio overview

FSP Technology Inc. has been granted 71 US utility patents between 2015 and 2025, placing FSP Technology Inc. at rank #4,877 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.4 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, FSP Technology Inc. is one of the more focused assignees in the PatentsView dataset. By volume, FSP sits between Composecure, Llc (71 patents, rank #4,873) and Handylab, Inc. (71 patents, rank #4,881) - the closest US assignees by grant volume. The composite Innovation Score of 45.1/100 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 24 grants, compared with 47 in the 2015–2019 window, a -49% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. FSP Technology Inc.'s 12.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FSP Technology Inc. against peers pursuing similar technology classes.

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.
