Overall rank by patents
#898
Across all tracked assignees
USPTO PatentsView assignee record — 500 granted patents across 91 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS).
CHINA PETROLEUM & CHEMICAL CORPORATION has been granted 500 US utility patents between 2015 and 2025, placing CHINA PETROLEUM & CHEMICAL CORPORATION at rank #898 across all assignees tracked by PlainPatent. This portfolio spans 91 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.6 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, CHINA PETROLEUM & CHEMICAL CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 66.3/100 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 302 grants, compared with 198 in the 2015–2019 window — a +53% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 PETROLEUM & CHEMICAL CORPORATION's 18.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 91 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CHINA PETROLEUM & CHEMICAL CORPORATION against peers pursuing similar technology classes.
