USPTO PatentsView assignee record - 78 granted patents across 82 technology areas, active 2016–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25J (MANIPULATORS; CHAMBERS PROVIDED WITH MANIPULATION DEVICES).
The verdict
Yanshan holds 78 US patents across 82 technology areas, rank #4,544 of 50,000 tracked assignees.
Yanshan University has been granted 78 US utility patents between 2016 and 2025, placing Yanshan University at rank #4,544 across all assignees tracked by PlainPatent. This portfolio spans 82 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in B25J (MANIPULATORS; CHAMBERS PROVIDED WITH MANIPULATION DEVICES). As a Foreign Corporation, Yanshan University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yanshan sits between Valtech Cardio Ltd. (78 patents, rank #4,540) and Bizerba SE & Co. KG (77 patents, rank #4,548) - the closest US assignees by grant volume. The composite Innovation Score of 64.7/100 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 72 grants, compared with 6 in the 2015–2019 window, a +1100% 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. Yanshan University's 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 82 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yanshan University against peers pursuing similar technology classes.

How to use this portfolio
Yanshan's 78 grants land it in the top 2% 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.
