Portfolio overview

Zhejiang Sunny Optical Co., Ltd has been granted 192 US utility patents between 2019 and 2025, placing Zhejiang Sunny Optical Co., Ltd at rank #2,070 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Zhejiang Sunny Optical Co., Ltd is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 49.5/100 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 191 grants, compared with 1 in the 2015–2019 window — a +19000% 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. Zhejiang Sunny Optical Co., Ltd's 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhejiang Sunny Optical Co., Ltd against peers pursuing similar technology classes.
