Portfolio overview

WING TAK LEE Silicone Rubber Technology (shenzhen) Co., Ltd has been granted 8 US utility patents between 2017 and 2021, placing WING TAK LEE Silicone Rubber Technology (shenzhen) Co., Ltd at rank #33,861 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.3 claims per patent with primary concentration in H04M (TELEPHONIC COMMUNICATION). As a Foreign Corporation, WING TAK LEE Silicone Rubber Technology (shenzhen) Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, WING sits between Wilkinson Ecological Design (8 patents, rank #33,857) and WON Kwang S&T Co., Ltd. (8 patents, rank #33,865) - the closest US assignees by grant volume. The composite Innovation Score of 23.8/100 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 7 grants, compared with 1 in the 2015–2019 window, a +600% 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. WING TAK LEE Silicone Rubber Technology (shenzhen) Co., Ltd's 4.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark WING TAK LEE Silicone Rubber Technology (shenzhen) Co., Ltd against peers pursuing similar technology classes.
