USPTO PatentsView assignee record - 33 granted patents across 9 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25C (HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS).
The verdict
APEX holds 33 US patents across 9 technology areas, rank #9,425 of 50,000 tracked assignees.
APEX MFG. Co., Ltd. has been granted 33 US utility patents between 2015 and 2025, placing APEX MFG. Co., Ltd. at rank #9,425 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in B25C (HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS). As a Foreign Corporation, APEX MFG. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, APEX sits between Agency ARMS, Llc (33 patents, rank #9,421) and Aircraft Medical Limited (33 patents, rank #9,429) - the closest US assignees by grant volume. The composite Innovation Score of 30.3/100 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 21 grants, compared with 12 in the 2015–2019 window, a +75% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. APEX MFG. Co., Ltd.'s 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark APEX MFG. Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
APEX's 33 grants land it in the top 66% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
