USPTO PatentsView assignee record - 5 granted patents across 3 technology areas, active 2020–2021. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G01V (GEOPHYSICS; GRAVITATIONAL MEASUREMENTS; DETECTING MASSES OR OBJECTS; TAGS).
The verdict
Research holds 5 US patents across 3 technology areas, rank #49,978 of 50,000 tracked assignees.
Research Institute OF Petroleum Exploration & Development, Petrochina Company Limited has been granted 5 US utility patents between 2020 and 2021, placing Research Institute OF Petroleum Exploration & Development, Petrochina Company Limited at rank #49,978 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in G01V (GEOPHYSICS; GRAVITATIONAL MEASUREMENTS; DETECTING MASSES OR OBJECTS; TAGS). As a Foreign Corporation, Research Institute OF Petroleum Exploration & Development, Petrochina Company Limited is one of the more focused assignees in the PatentsView dataset. By volume, Research sits between Renewable Power Conversion, Inc. (5 patents, rank #49,974) and Responsys, Inc. (5 patents, rank #49,982) - the closest US assignees by grant volume. The composite Innovation Score of 22.1/100 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 2020 through 2021, with 5 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. Research Institute OF Petroleum Exploration & Development, Petrochina Company Limited's 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Research Institute OF Petroleum Exploration & Development, Petrochina Company Limited against peers pursuing similar technology classes.

How to use this portfolio
Research's 5 grants land it in the top 90% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
