Portfolio overview

Ocean Power Technologies, Inc. has been granted 10 US utility patents between 2015 and 2025, placing Ocean Power Technologies, Inc. at rank #27,008 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Ocean Power Technologies, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ocean sits between Nuvox Pharma Llc (10 patents, rank #27,004) and ODL, Incorporated (10 patents, rank #27,012) - the closest US assignees by grant volume. The composite Innovation Score of 36.2/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Ocean Power Technologies, Inc.'s 17.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ocean Power Technologies, Inc. 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.
