RICHTEK TECHNOLOGY CORPORATION

RICHTEK TECHNOLOGY CORPORATION has been granted 448 US utility patents between 2015 and 2025, placing RICHTEK TECHNOLOGY CORPORATION at rank #981 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 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, RICHTEK TECHNOLOGY CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.9/100 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 211 grants, compared with 237 in the 2015–2019 window — a -11% 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. RICHTEK TECHNOLOGY CORPORATION's 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark RICHTEK TECHNOLOGY CORPORATION against peers pursuing similar technology classes.
