Portfolio overview

Wuhan Research Institute OF Materials Protection has been granted 6 US utility patents between 2022 and 2025, placing Wuhan Research Institute OF Materials Protection at rank #44,027 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a Foreign Corporation, Wuhan Research Institute OF Materials Protection is one of the more focused assignees in the PatentsView dataset. By volume, Wuhan sits between Worldmate, Ltd. (6 patents, rank #44,023) and Wagner Spraytech (uk) Ltd. (6 patents, rank #44,031) - the closest US assignees by grant volume. The composite Innovation Score of 44.4/100 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 6 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. Wuhan Research Institute OF Materials Protection's 6.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wuhan Research Institute OF Materials Protection against peers pursuing similar technology classes.
