Portfolio overview

P-TECH CO., LTD. has been granted 134 US utility patents between 2015 and 2025, placing P-TECH CO., LTD. at rank #2,862 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.2 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, P-TECH CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 58.8/100 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 68 grants, compared with 66 in the 2015–2019 window — a +3% 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. P-TECH CO., LTD.'s 21.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark P-TECH CO., LTD. against peers pursuing similar technology classes.
