Portfolio overview

Bardex Corporation has been granted 16 US utility patents between 2015 and 2025, placing Bardex Corporation at rank #17,505 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 28.1 claims per patent with primary concentration in B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING). As a US Corporation, Bardex Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Bardex sits between Butler Engineering AND Marketing S.p.a. (16 patents, rank #17,501) and Bio Capital Holdings, Llc (16 patents, rank #17,509) - the closest US assignees by grant volume. The composite Innovation Score of 41.1/100 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 11 grants, compared with 5 in the 2015–2019 window, a +120% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Bardex Corporation's 28.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bardex Corporation 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.
