Portfolio overview

Waterway Plastics has been granted 11 US utility patents between 2015 and 2022, placing Waterway Plastics at rank #25,530 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in A61H (PHYSICAL THERAPY APPARATUS, e.g. DEVICES FOR LOCATING OR STIMULATING REFLEX POINTS IN THE BODY; ARTIFICIAL RESPIRATION; MASSAGE; BATHING DEVICES FOR SPECIAL THERAPEUTIC OR HYGIENIC PURPOSES OR SPECIFI). As a US Corporation, Waterway Plastics is one of the more focused assignees in the PatentsView dataset. By volume, Waterway sits between Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences (11 patents, rank #25,526) and Wein Holding, Llc (11 patents, rank #25,534) - the closest US assignees by grant volume. The composite Innovation Score of 29.0/100 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 3 grants, compared with 8 in the 2015–2019 window, a -62% 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. Waterway Plastics's 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Waterway Plastics 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.
