Portfolio overview

AT&T Intellectual Property I, L.p. has been granted 9,554 US utility patents between 2015 and 2025, placing AT&T Intellectual Property I, L.p. at rank #38 across all assignees tracked by PlainPatent. This portfolio spans 162 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.3 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a US Corporation, AT&T Intellectual Property I, L.p. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, At&t sits between SK Hynix Inc. (9,830 patents, rank #34) and LG Display Co., Ltd. (8,410 patents, rank #42) - the closest US assignees by grant volume. The composite Innovation Score of 71.6/100 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 4,215 grants, compared with 5,339 in the 2015–2019 window, a -21% 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. AT&T Intellectual Property I, L.p.'s 19.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AT&T Intellectual Property I, L.p. against peers pursuing similar technology classes.
