Portfolio overview

FIH (hong Kong) Limited has been granted 148 US utility patents between 2015 and 2024, placing FIH (hong Kong) Limited at rank #2,627 across all assignees tracked by PlainPatent. This portfolio spans 79 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in H01Q (ANTENNAS, i.e. RADIO AERIALS). As a Foreign Corporation, FIH (hong Kong) Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, FIH sits between Barefoot Networks, Inc. (148 patents, rank #2,623) and Mitsubishi Aircraft Corporation (148 patents, rank #2,631) - the closest US assignees by grant volume. The composite Innovation Score of 52.6/100 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 12 grants, compared with 136 in the 2015–2019 window, a -91% 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. FIH (hong Kong) Limited's 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 79 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FIH (hong Kong) Limited 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.
