Portfolio overview

Starjet Technologies Co., Ltd has been granted 7 US utility patents between 2015 and 2015, placing Starjet Technologies Co., Ltd at rank #37,483 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.4 claims per patent with primary concentration in F41B (WEAPONS FOR PROJECTING MISSILES WITHOUT USE OF EXPLOSIVE OR COMBUSTIBLE PROPELLANT CHARGE; WEAPONS NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Starjet Technologies Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Starjet sits between SSM Schärer Schweiter Mettler Ag (7 patents, rank #37,479) and STEK Co., Ltd. (7 patents, rank #37,487) - the closest US assignees by grant volume. The composite Innovation Score of 18.0/100 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 0 grants, compared with 7 in the 2015–2019 window, a -100% 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. Starjet Technologies Co., Ltd's 1.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Starjet Technologies Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio

Starjet's 7 grants land it in the top 95% 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 - Starjet ranks #37,483 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F41B - see who else leads that technology area. F41B 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.
