Portfolio overview

EST Group, Inc. has been granted 9 US utility patents between 2017 and 2024, placing EST Group, Inc. at rank #28,655 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a US Corporation, EST Group, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, EST sits between Ericsson Gmbh (9 patents, rank #28,651) and Evergrande NEW Energy Automotive Investment Holdings Group Co., Ltd. (9 patents, rank #28,659) - the closest US assignees by grant volume. The composite Innovation Score of 48.4/100 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 4 grants, compared with 5 in the 2015–2019 window, a -20% 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. EST Group, Inc.'s 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EST Group, Inc. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
