Portfolio overview

Silicon Storage Technology, Inc. has been granted 294 US utility patents between 2015 and 2025, placing Silicon Storage Technology, Inc. at rank #1,428 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in G11C (STATIC STORES). As a US Corporation, Silicon Storage Technology, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Silicon sits between Nucurrent, Inc. (295 patents, rank #1,424) and Grohe Ag (292 patents, rank #1,432) - the closest US assignees by grant volume. The composite Innovation Score of 49.1/100 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 176 grants, compared with 118 in the 2015–2019 window, a +49% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Silicon Storage Technology, Inc.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silicon Storage Technology, Inc. against peers pursuing similar technology classes.

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.
