Portfolio overview

HAKKO CORPORATION has been granted 64 US utility patents between 2015 and 2025, placing HAKKO CORPORATION at rank #5,363 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.2 claims per patent with primary concentration in B23K (SOLDERING OR UNSOLDERING; WELDING; CLADDING OR PLATING BY SOLDERING OR WELDING; CUTTING BY APPLYING HEAT LOCALLY, e.g. FLAME CUTTING; WORKING BY LASER BEAM). As a Foreign Corporation, HAKKO CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 39.7/100 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 35 grants, compared with 29 in the 2015–2019 window — a +21% 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. HAKKO CORPORATION's 9.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HAKKO CORPORATION against peers pursuing similar technology classes.

How to use this portfolio

Hakko's 64 grants land it in the top 37% by Innovation Score — but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance — Hakko ranks #5,363 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B23K — see who else leads that technology area. B23K leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
