Portfolio overview

Shanghai Makesens Energy Storage Technology Co., Ltd. has been granted 8 US utility patents between 2024 and 2025, placing Shanghai Makesens Energy Storage Technology Co., Ltd. at rank #33,349 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Shanghai Makesens Energy Storage Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Seton Hall University (8 patents, rank #33,345) and Shantou Kailan Technology Industrial Co. (8 patents, rank #33,353) - the closest US assignees by grant volume. The composite Innovation Score of 44.6/100 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. Historical data spans 2024 through 2025, with 8 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Shanghai Makesens Energy Storage Technology Co., Ltd.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Makesens Energy Storage Technology Co., Ltd. against peers pursuing similar technology classes.
