Portfolio overview

Yejia Optical Technology (guangdong) Corporation has been granted 6 US utility patents between 2020 and 2025, placing Yejia Optical Technology (guangdong) Corporation at rank #44,151 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Yejia Optical Technology (guangdong) Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Yejia sits between Yamato Protec Corporation (6 patents, rank #44,147) and Yongfeng Boyuan Industry Co., Ltd., Jiangxi Province (6 patents, rank #44,155) - the closest US assignees by grant volume. The composite Innovation Score of 24.7/100 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. Historical data spans 2020 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Yejia Optical Technology (guangdong) Corporation's 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yejia Optical Technology (guangdong) Corporation 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.
