Portfolio overview

National Engineering Research Center Of Advanced Energy Storage Materials (shenzhen) Co., Ltd has been granted 10 US utility patents between 2018 and 2025, placing National Engineering Research Center Of Advanced Energy Storage Materials (shenzhen) Co., Ltd at rank #26,963 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a Foreign Corporation, National Engineering Research Center Of Advanced Energy Storage Materials (shenzhen) Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Nanomix, Inc. (10 patents, rank #26,959) and Natural Alternatives International, Inc. (10 patents, rank #26,967) - the closest US assignees by grant volume. The composite Innovation Score of 46.6/100 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 9 grants, compared with 1 in the 2015–2019 window, a +800% 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. National Engineering Research Center Of Advanced Energy Storage Materials (shenzhen) Co., Ltd's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Engineering Research Center Of Advanced Energy Storage Materials (shenzhen) Co., Ltd against peers pursuing similar technology classes.
