Portfolio overview

Ememory Technology Inc. has been granted 261 US utility patents between 2015 and 2025, placing Ememory Technology Inc. at rank #1,585 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in G11C (STATIC STORES). As a Foreign Corporation, Ememory Technology Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ememory sits between National University Corporation Hokkaido University (262 patents, rank #1,581) and Eagle Technology, Llc (260 patents, rank #1,589) - the closest US assignees by grant volume. The composite Innovation Score of 51.0/100 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 137 grants, compared with 124 in the 2015–2019 window, a +10% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Ememory Technology Inc.'s 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ememory Technology 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.
