Portfolio overview

Rexon Industrial Corp., Ltd. has been granted 58 US utility patents between 2015 and 2025, placing Rexon Industrial Corp., Ltd. at rank #5,872 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 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, Rexon Industrial Corp., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Rexon sits between PTC Inc. (58 patents, rank #5,868) and Real Value Llc (58 patents, rank #5,876) - the closest US assignees by grant volume. The composite Innovation Score of 39.2/100 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 15 grants, compared with 43 in the 2015–2019 window, a -65% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Rexon Industrial Corp., Ltd.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rexon Industrial Corp., Ltd. 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.
