Portfolio overview

China Academy OF Telecommunications Technology has been granted 520 US utility patents between 2015 and 2023, placing China Academy OF Telecommunications Technology at rank #867 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in H04W (WIRELESS COMMUNICATION NETWORKS). As a Foreign Corporation, China Academy OF Telecommunications Technology is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Echostar Technologies L.l.c. (525 patents, rank #863) and OPEN TEXT Sa ULC (518 patents, rank #871) - the closest US assignees by grant volume. The composite Innovation Score of 47.2/100 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 187 grants, compared with 333 in the 2015–2019 window, a -44% 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. China Academy OF Telecommunications Technology's 14.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China Academy OF Telecommunications Technology against peers pursuing similar technology classes.

How to use this portfolio

China's 520 grants land it in the top 19% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - China ranks #867 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04W - see who else leads that technology area. H04W leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
