Portfolio overview
DE NORA PERMELEC LTD has been granted 33 US utility patents between 2016 and 2025, placing DE NORA PERMELEC LTD at rank #9,481 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 claims per patent with primary concentration in C25B (ELECTROLYTIC OR ELECTROPHORETIC PROCESSES FOR THE PRODUCTION OF COMPOUNDS OR NON-METALS; APPARATUS THEREFOR). As a Foreign Corporation, DE NORA PERMELEC LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 37.6/100 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 25 grants, compared with 8 in the 2015–2019 window — a +213% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. DE NORA PERMELEC LTD's 8.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DE NORA PERMELEC LTD against peers pursuing similar technology classes.
