Portfolio overview

Corning Optical Communications Llc has been granted 828 US utility patents between 2015 and 2025, placing Corning Optical Communications Llc at rank #539 across all assignees tracked by PlainPatent. This portfolio spans 89 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a US Corporation, Corning Optical Communications Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Corning sits between Exxonmobil Upstream Research Company (841 patents, rank #535) and Silicon Laboratories Inc. (825 patents, rank #543) - the closest US assignees by grant volume. The composite Innovation Score of 61.3/100 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 265 grants, compared with 563 in the 2015–2019 window, a -53% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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 Llc's 18.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 89 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Corning Optical Communications Llc against peers pursuing similar technology classes.
