Portfolio overview

Powertech Technology Inc. has been granted 133 US utility patents between 2015 and 2025, placing Powertech Technology Inc. at rank #2,883 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Powertech Technology Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Powertech sits between HOYA LENS Thailand Ltd. (133 patents, rank #2,879) and Cambricon Technologies Corporation Limited (132 patents, rank #2,887) - the closest US assignees by grant volume. The composite Innovation Score of 45.0/100 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. Between 2020 and 2025 the company received 67 grants, compared with 66 in the 2015–2019 window, a +2% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Powertech Technology Inc.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Powertech 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.
