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 #17,381 of 50,000 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. By volume, Zhuhai sits between Zeroplus Technology Co., Ltd. (17 patents, rank #17,373) and ZOOM International A.s. (17 patents, rank #17,381) - the closest US assignees by grant volume. The composite Innovation Score of 46.4/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 17 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Zhuhai Sailner 3D Technology Co., Ltd.'s 13.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 15 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
