Portfolio overview

Sunrise Memory Corporation has been granted 121 US utility patents between 2017 and 2025, placing Sunrise Memory Corporation at rank #3,125 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.4 claims per patent with primary concentration in H10B (ELECTRONIC MEMORY DEVICES). As a US Corporation, Sunrise Memory Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Sunrise sits between Institute Of Automation, Chinese Academy Of Sciences (121 patents, rank #3,121) and Atombeam Technologies Inc. (120 patents, rank #3,129) - the closest US assignees by grant volume. The composite Innovation Score of 55.3/100 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 110 grants, compared with 11 in the 2015–2019 window, a +900% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Sunrise Memory Corporation's 27.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sunrise Memory Corporation against peers pursuing similar technology classes.

How to use this portfolio

Sunrise's 121 grants land it in the top 7% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Sunrise ranks #3,125 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H10B - see who else leads that technology area. H10B leaders
  • 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.
