Portfolio overview

Xi'an University OF Posts & Telecommunications has been granted 11 US utility patents between 2022 and 2025, placing Xi'an University OF Posts & Telecommunications at rank #25,553 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Xi'an University OF Posts & Telecommunications is one of the more focused assignees in the PatentsView dataset. By volume, Xi'an sits between Wound Care Technologies, Inc. (11 patents, rank #25,549) and Xtreme Marine Corporation (11 patents, rank #25,557) - the closest US assignees by grant volume. The composite Innovation Score of 48.1/100 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. Historical data spans 2022 through 2025, with 11 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Xi'an University OF Posts & Telecommunications's 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xi'an University OF Posts & Telecommunications against peers pursuing similar technology classes.
