Portfolio overview
KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTD has been granted 29 US utility patents between 2015 and 2021, placing KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTD at rank #10,661 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.9 claims per patent with primary concentration in B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING). As a Foreign Corporation, KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.1/100 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 7 grants, compared with 22 in the 2015–2019 window — a -68% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTD's 12.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KEPPEL OFFSHORE & MARINE TECHNOLOGY CENTRE PTE LTD against peers pursuing similar technology classes.
