Portfolio overview

The Charles Stark Draper Laboratory, Inc. has been granted 446 US utility patents between 2015 and 2025, placing The Charles Stark Draper Laboratory, Inc. at rank #989 across all assignees tracked by PlainPatent. This portfolio spans 143 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 claims per patent with primary concentration in G01C (MEASURING DISTANCES, LEVELS OR BEARINGS; SURVEYING; NAVIGATION; GYROSCOPIC INSTRUMENTS; PHOTOGRAMMETRY OR VIDEOGRAMMETRY). As a US Corporation, The Charles Stark Draper Laboratory, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, The sits between Universal City Studios Llc (447 patents, rank #985) and Daifuku Co., Ltd. (443 patents, rank #993) - the closest US assignees by grant volume. The composite Innovation Score of 61.7/100 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 215 grants, compared with 231 in the 2015–2019 window, a -7% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. The Charles Stark Draper Laboratory, Inc.'s 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark The Charles Stark Draper Laboratory, Inc. against peers pursuing similar technology classes.
