Portfolio overview

Qingdao National Laboratory Of Marine Science And Technology Development Center has been granted 5 US utility patents between 2022 and 2025, placing Qingdao National Laboratory Of Marine Science And Technology Development Center at rank #49,898 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.0 claims per patent with primary concentration in B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING). As a Foreign Corporation, Qingdao National Laboratory Of Marine Science And Technology Development Center is one of the more focused assignees in the PatentsView dataset. By volume, Qingdao sits between Quirky IP Licensing Llc (5 patents, rank #49,894) and Quadra Manufacturing, Llc (5 patents, rank #49,902) - the closest US assignees by grant volume. The composite Innovation Score of 42.4/100 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 2022 through 2025, with 5 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. Qingdao National Laboratory Of Marine Science And Technology Development Center's 5.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Qingdao National Laboratory Of Marine Science And Technology Development Center against peers pursuing similar technology classes.
