The verdict
Won-door holds 36 US patents across 21 technology areas, rank #8,966 of 50,000 tracked assignees.
Won-door Corporation has been granted 36 US utility patents between 2015 and 2025, placing Won-door Corporation at rank #8,966 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.5 claims per patent with primary concentration in E05Y (INDEXING SCHEME ASSOCIATED WITH SUBCLASSES E05D AND E05F, RELATING TO CONSTRUCTION ELEMENTS, ELECTRIC CONTROL, POWER SUPPLY, POWER SIGNAL OR TRANSMISSION, USER INTERFACES, MOUNTING OR COUPLING, DETAIL). As a US Corporation, Won-door Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Won-door sits between Voxer IP Llc (36 patents, rank #8,962) and AIT Austrian Institute OF Technology Gmbh (35 patents, rank #8,970) - the closest US assignees by grant volume. The composite Innovation Score of 42.6/100 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 10 grants, compared with 26 in the 2015–2019 window, a -62% 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. Won-door Corporation's 19.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Won-door Corporation against peers pursuing similar technology classes.

How to use this portfolio
Won-door's 36 grants land it in the top 30% 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.
