The verdict
Tianjin holds 8 US patents across 6 technology areas, rank #33,648 of 50,000 tracked assignees.
Tianjin Deepfar Ocean Technology Co., Ltd. has been granted 8 US utility patents between 2019 and 2021, placing Tianjin Deepfar Ocean Technology Co., Ltd. at rank #33,648 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.3 claims per patent with primary concentration in B63G (OFFENSIVE OR DEFENSIVE ARRANGEMENTS ON VESSELS; MINE-LAYING; MINE-SWEEPING; SUBMARINES; AIRCRAFT CARRIERS). As a Foreign Corporation, Tianjin Deepfar Ocean Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tianjin sits between Threatconnect, Inc. (8 patents, rank #33,644) and Time To Act Limited (8 patents, rank #33,652) - the closest US assignees by grant volume. The composite Innovation Score of 19.4/100 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 2 in the 2015–2019 window, a +200% 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. Tianjin Deepfar Ocean Technology Co., Ltd.'s 5.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tianjin Deepfar Ocean Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Tianjin's 8 grants land it in the top 94% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
