Portfolio overview

Nanchang O-film Optical-electronic TECH Co., Ltd. has been granted 16 US utility patents between 2019 and 2021, placing Nanchang O-film Optical-electronic TECH Co., Ltd. at rank #17,918 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Nanchang O-film Optical-electronic TECH Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 27.9/100 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 13 grants, compared with 3 in the 2015–2019 window, a +333% 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. Nanchang O-film Optical-electronic TECH Co., Ltd.'s 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanchang O-film Optical-electronic TECH Co., Ltd. against peers pursuing similar technology classes.
