Portfolio overview

Piolax, Inc. has been granted 126 US utility patents between 2015 and 2025, placing Piolax, Inc. at rank #3,022 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in B60R (VEHICLES, VEHICLE FITTINGS, OR VEHICLE PARTS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Piolax, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Piolax sits between L3harris Technologies, Inc. (126 patents, rank #3,018) and Sogang University Research Foundation (126 patents, rank #3,026) - the closest US assignees by grant volume. The composite Innovation Score of 51.2/100 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 59 grants, compared with 67 in the 2015–2019 window, a -12% 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. Piolax, Inc.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Piolax, Inc. against peers pursuing similar technology classes.
