Portfolio overview
Fairchild Korea Semiconductor Ltd. has been granted 78 US utility patents between 2015 and 2021, placing Fairchild Korea Semiconductor Ltd. at rank #4,510 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 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, Fairchild Korea Semiconductor Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.6/100 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 1 grants, compared with 77 in the 2015–2019 window — a -99% 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. Fairchild Korea Semiconductor Ltd.'s 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Fairchild Korea Semiconductor Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Fairchild's 78 grants land it in the top 28% by Innovation Score — but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance — Fairchild ranks #4,510 of 50,000. Top 50 holders
- Most of this portfolio concentrates in H02M — see who else leads that technology area. H02M leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
