USPTO PatentsView assignee record - 10 granted patents across 5 technology areas, active 2015–2016. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES).
The verdict
Zenith holds 10 US patents across 5 technology areas, rank #27,900 of 50,000 tracked assignees.
Zenith Products Corporation has been granted 10 US utility patents between 2015 and 2016, placing Zenith Products Corporation at rank #27,900 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES). As a US Corporation, Zenith Products Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Zenith sits between Zeality Inc (10 patents, rank #27,896) and Zhongshan Yusen Lighting Technology Co., Ltd. (10 patents, rank #27,904) - the closest US assignees by grant volume. The composite Innovation Score of 22.1/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. Zenith Products Corporation's 9.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zenith Products Corporation against peers pursuing similar technology classes.

How to use this portfolio
Zenith's 10 grants land it in the top 90% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
