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. By volume, Zhejiang sits between Quantum Corporation (192 patents, rank #2,066) and Sanken Electric Co., Ltd. (191 patents, rank #2,074) - the closest US assignees by grant volume. 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.

How to use this portfolio
Zhejiang's 192 grants land it in the top 15% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Zhejiang ranks #2,070 of 50,000. Top 50 holders
- Most of this portfolio concentrates in G02B - see who else leads that technology area. G02B leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
