Portfolio overview

Ningbo Sanhan Alloy Material Co., Ltd. has been granted 10 US utility patents between 2022 and 2025, placing Ningbo Sanhan Alloy Material Co., Ltd. at rank #26,987 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in Y02P (CLIMATE CHANGE MITIGATION TECHNOLOGIES IN THE PRODUCTION OR PROCESSING OF GOODS). As a Foreign Corporation, Ningbo Sanhan Alloy Material Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ningbo sits between Nice North America Llc (10 patents, rank #26,983) and Nordic Lights Oy (10 patents, rank #26,991) - the closest US assignees by grant volume. The composite Innovation Score of 51.8/100 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 2022 through 2025, with 10 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. Ningbo Sanhan Alloy Material Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ningbo Sanhan Alloy Material Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
