Portfolio overview

Corning Optical Communications Wireless Ltd has been granted 119 US utility patents between 2015 and 2019, placing Corning Optical Communications Wireless Ltd at rank #3,155 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.3 claims per patent with primary concentration in H04B (TRANSMISSION). As a Foreign Corporation, Corning Optical Communications Wireless Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Corning sits between Ambit Microsystems (shanghai) Ltd. (119 patents, rank #3,151) and Nippon Steel Chemical & Material Co., Ltd. (119 patents, rank #3,159) - the closest US assignees by grant volume. The composite Innovation Score of 47.7/100 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. Between 2020 and 2025 the company received 0 grants, compared with 119 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Corning Optical Communications Wireless Ltd's 20.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, 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 Corning Optical Communications Wireless Ltd against peers pursuing similar technology classes.
