Portfolio overview

Monolithic 3D Inc. has been granted 329 US utility patents between 2015 and 2025, placing Monolithic 3D Inc. at rank #1,286 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a US Corporation, Monolithic 3D Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Monolithic sits between Southwest Research Institute (330 patents, rank #1,282) and Safran (328 patents, rank #1,290) - the closest US assignees by grant volume. The composite Innovation Score of 61.2/100 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 250 grants, compared with 79 in the 2015–2019 window, a +216% 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. Monolithic 3D Inc.'s 19.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Monolithic 3D Inc. against peers pursuing similar technology classes.

How to use this portfolio

Monolithic's 329 grants land it in the top 3% 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 - Monolithic ranks #1,286 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H01L - see who else leads that technology area. H01L 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.
