Portfolio overview

Silicon Laboratories Inc. has been granted 825 US utility patents between 2015 and 2025, placing Silicon Laboratories Inc. at rank #543 across all assignees tracked by PlainPatent. This portfolio spans 76 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a US Corporation, Silicon Laboratories Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Silicon sits between Corning Optical Communications Llc (828 patents, rank #539) and NGK Spark PLUG Co., Ltd. (823 patents, rank #547) - the closest US assignees by grant volume. The composite Innovation Score of 64.8/100 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 420 grants, compared with 405 in the 2015–2019 window, a +4% 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 Laboratories 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 76 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silicon Laboratories 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.
