Portfolio overview

FINE Sinter Co., Ltd. has been granted 12 US utility patents between 2015 and 2023, placing FINE Sinter Co., Ltd. at rank #22,571 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.6 claims per patent with primary concentration in B22F (WORKING METALLIC POWDER; MANUFACTURE OF ARTICLES FROM METALLIC POWDER; MAKING METALLIC POWDER ; APPARATUS OR DEVICES SPECIALLY ADAPTED FOR METALLIC POWDER). As a Foreign Corporation, FINE Sinter Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, FINE sits between Fiery, Llc (12 patents, rank #22,567) and Fives Machining Systems, Inc. (12 patents, rank #22,575) - the closest US assignees by grant volume. The composite Innovation Score of 40.1/100 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 6 grants, compared with 6 in the 2015–2019 window, a +0% 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. FINE Sinter Co., Ltd.'s 6.6 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 FINE Sinter Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

FINE's 12 grants land it in the top 36% 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 - FINE ranks #22,571 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B22F - see who else leads that technology area. B22F 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.
