Portfolio overview

Ningbo Sunny Opotech Co., Ltd. has been granted 227 US utility patents between 2017 and 2025, placing Ningbo Sunny Opotech Co., Ltd. at rank #1,798 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). As a Foreign Corporation, Ningbo Sunny Opotech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ningbo sits between Grammer Ag (227 patents, rank #1,794) and Atlas Copco Airpower, Naamloze Vennootschap (226 patents, rank #1,802) - the closest US assignees by grant volume. The composite Innovation Score of 56.9/100 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 176 grants, compared with 51 in the 2015–2019 window, a +245% 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. Ningbo Sunny Opotech Co., Ltd.'s 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ningbo Sunny Opotech Co., Ltd. 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.
