The verdict
Jessem holds 7 US patents across 9 technology areas, rank #36,034 of 50,000 tracked assignees.
Jessem Tool Corporation has been granted 7 US utility patents between 2021 and 2025, placing Jessem Tool Corporation at rank #36,034 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.4 claims per patent with primary concentration in B23D (PLANING; SLOTTING; SHEARING; BROACHING; SAWING; FILING; SCRAPING; LIKE OPERATIONS FOR WORKING METAL BY REMOVING MATERIAL, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Jessem Tool Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Jessem sits between Jellisee Ophthalmics Inc. (7 patents, rank #36,030) and Jiangsu Cherrity Optronics Co., Ltd. (7 patents, rank #36,038) - the closest US assignees by grant volume. The composite Innovation Score of 51.9/100 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. Historical data spans 2021 through 2025, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign 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. Jessem Tool Corporation's 23.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jessem Tool Corporation against peers pursuing similar technology classes.

How to use this portfolio
Jessem's 7 grants land it in the top 11% 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.
