The verdict
J.h. holds 18 US patents across 20 technology areas, rank #16,120 of 50,000 tracked assignees.
J.h. Fletcher & Co. has been granted 18 US utility patents between 2015 and 2025, placing J.h. Fletcher & Co. at rank #16,120 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a US Corporation, J.h. Fletcher & Co. is one of the more focused assignees in the PatentsView dataset. By volume, J.h. sits between Intraaction Corp. (18 patents, rank #16,116) and JDI Design AND Development G.k. (18 patents, rank #16,124) - the closest US assignees by grant volume. The composite Innovation Score of 52.5/100 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 12 grants, compared with 6 in the 2015–2019 window, a +100% 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. J.h. Fletcher & Co.'s 18.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark J.h. Fletcher & Co. against peers pursuing similar technology classes.

How to use this portfolio
J.h.'s 18 grants land it in the top 10% 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.
