Across all tracked assignees
USPTO PatentsView assignee record - 6 granted patents across 7 technology areas, active 2023–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP).
The verdict
Nanofilm holds 6 US patents across 7 technology areas, rank #41,944 of 50,000 tracked assignees.
Nanofilm Technologies International Limited has been granted 6 US utility patents between 2023 and 2024, placing Nanofilm Technologies International Limited at rank #41,944 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.7 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a Foreign Corporation, Nanofilm Technologies International Limited is one of the more focused assignees in the PatentsView dataset. By volume, Nanofilm sits between Nano Vation Therapeutics Inc. (6 patents, rank #41,940) and Nantong Schmidt Opto-electrical Technology Co. Ltd. (6 patents, rank #41,948) - the closest US assignees by grant volume. The composite Innovation Score of 46.7/100 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 2023 through 2024, with 6 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. Nanofilm Technologies International Limited's 17.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanofilm Technologies International Limited against peers pursuing similar technology classes.

How to use this portfolio
Nanofilm's 6 grants land it in the top 20% 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.
