Portfolio overview

Centurylink Intellectual Property Llc has been granted 695 US utility patents between 2015 and 2025, placing Centurylink Intellectual Property Llc at rank #641 across all assignees tracked by PlainPatent. This portfolio spans 68 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a US Corporation, Centurylink Intellectual Property Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Centurylink sits between Inc Square, Co., Ltd (699 patents, rank #637) and Posco Co., Ltd (691 patents, rank #645) - the closest US assignees by grant volume. The composite Innovation Score of 63.3/100 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 294 grants, compared with 401 in the 2015–2019 window, a -27% 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. Centurylink Intellectual Property 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 68 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Centurylink Intellectual Property Llc against peers pursuing similar technology classes.
