Portfolio overview

GUANGDONG BESTEK E-COMMERCE CO., LTD. has been granted 51 US utility patents between 2016 and 2021, placing GUANGDONG BESTEK E-COMMERCE CO., LTD. at rank #6,535 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.9 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, GUANGDONG BESTEK E-COMMERCE CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 22.7/100 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 8 grants, compared with 43 in the 2015–2019 window — a -81% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. GUANGDONG BESTEK E-COMMERCE CO., LTD.'s 1.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark GUANGDONG BESTEK E-COMMERCE CO., LTD. against peers pursuing similar technology classes.
