Portfolio overview

ZHUHAI SAILNER 3D TECHNOLOGY CO., LTD. has been granted 17 US utility patents between 2021 and 2025, placing ZHUHAI SAILNER 3D TECHNOLOGY CO., LTD. at rank #17,377 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in B33Y (ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE ). As a Foreign Corporation, ZHUHAI SAILNER 3D TECHNOLOGY CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.4/100 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. Historical data spans 2021 through 2025, with 17 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. ZHUHAI SAILNER 3D TECHNOLOGY CO., LTD.'s 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZHUHAI SAILNER 3D TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.
