Portfolio overview

Nisca Corporation has been granted 84 US utility patents between 2015 and 2020, placing Nisca Corporation at rank #4,252 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in B65H (HANDLING THIN OR FILAMENTARY MATERIAL, e.g. SHEETS, WEBS, CABLES). As a Foreign Corporation, Nisca Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Nisca sits between Kitagawa Industries Co., Ltd. (84 patents, rank #4,248) and Qingdao Haier Joint Stock Co., Ltd. (84 patents, rank #4,256) - the closest US assignees by grant volume. The composite Innovation Score of 42.1/100 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 1 grants, compared with 83 in the 2015–2019 window, a -99% 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. Nisca Corporation's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nisca Corporation against peers pursuing similar technology classes.

How to use this portfolio

Nisca's 84 grants land it in the top 31% 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 - Nisca ranks #4,252 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B65H - see who else leads that technology area. B65H 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.
