Portfolio overview

Ennis-flint, Inc. has been granted 11 US utility patents between 2020 and 2025, placing Ennis-flint, Inc. at rank #24,294 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in C09D (COATING COMPOSITIONS, e.g. PAINTS, VARNISHES OR LACQUERS; FILLING PASTES; CHEMICAL PAINT OR INK REMOVERS; INKS; CORRECTING FLUIDS; WOODSTAINS; PASTES OR SOLIDS FOR COLOURING OR PRINTING; USE OF MATERI). As a US Corporation, Ennis-flint, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ennis-flint sits between Enerallies, Inc. (11 patents, rank #24,290) and Erwin Junker Maschinenfabrik Gmbh (11 patents, rank #24,298) - the closest US assignees by grant volume. The composite Innovation Score of 45.8/100 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 2020 through 2025, with 11 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Ennis-flint, Inc.'s 18.4 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 Ennis-flint, Inc. against peers pursuing similar technology classes.
