Portfolio overview

Silicon Works Co., Ltd. has been granted 337 US utility patents between 2015 and 2025, placing Silicon Works Co., Ltd. at rank #1,259 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.7 claims per patent with primary concentration in G09G (ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION). As a Foreign Corporation, Silicon Works Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Silicon sits between Universal Entertainment Corporation (338 patents, rank #1,255) and Cummins Emission Solutions Inc. (335 patents, rank #1,263) - the closest US assignees by grant volume. The composite Innovation Score of 62.2/100 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 229 grants, compared with 108 in the 2015–2019 window, a +112% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Silicon Works Co., Ltd.'s 14.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silicon Works Co., Ltd. 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.
