Portfolio overview

Bisn Tec Ltd. has been granted 31 US utility patents between 2018 and 2025, placing Bisn Tec Ltd. at rank #9,985 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Bisn Tec Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Bisn sits between Bruker Switzerland Ag (31 patents, rank #9,981) and Capacitor Sciences Incorporated (31 patents, rank #9,989) - the closest US assignees by grant volume. The composite Innovation Score of 41.5/100 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 23 grants, compared with 8 in the 2015–2019 window, a +188% 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. Bisn Tec Ltd.'s 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bisn Tec Ltd. against peers pursuing similar technology classes.
