Portfolio overview

Shin-etsu Polymer Co., Ltd. has been granted 92 US utility patents between 2015 and 2025, placing Shin-etsu Polymer Co., Ltd. at rank #3,945 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Shin-etsu Polymer Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Shin-etsu sits between Saint-gobain Centre DE Recherches ET D'etudes Europeen (92 patents, rank #3,941) and Videojet Technologies Inc. (92 patents, rank #3,949) - the closest US assignees by grant volume. The composite Innovation Score of 52.5/100 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 54 grants, compared with 38 in the 2015–2019 window, a +42% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Shin-etsu Polymer Co., Ltd.'s 9.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shin-etsu Polymer Co., Ltd. against peers pursuing similar technology classes.
