The verdict
Pro-tech holds 11 US patents across 6 technology areas, rank #25,017 of 50,000 tracked assignees.
Pro-tech Manufacturing And Distribution, Inc. has been granted 11 US utility patents between 2015 and 2023, placing Pro-tech Manufacturing And Distribution, Inc. at rank #25,017 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in E01H (STREET CLEANING; CLEANING OF PERMANENT WAYS; CLEANING BEACHES; DISPERSING ; OR PREVENTING; FOG IN GENERAL ; CLEANING STREET OR RAILWAY FURNITURE OR TUNNEL WALLS). As a US Corporation, Pro-tech Manufacturing And Distribution, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Pro-tech sits between Press-seal Corporation (11 patents, rank #25,013) and Progressive Sterilization, Llc (11 patents, rank #25,021) - the closest US assignees by grant volume. The composite Innovation Score of 27.3/100 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 4 in the 2015–2019 window, a +75% 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. Pro-tech Manufacturing And Distribution, Inc.'s 12.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Pro-tech Manufacturing And Distribution, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Pro-tech's 11 grants land it in the top 77% 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.
