Portfolio overview

Joint Stock Company “rosenergoatom” has been granted 8 US utility patents between 2020 and 2024, placing Joint Stock Company “rosenergoatom” at rank #32,157 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in G21F (PROTECTION AGAINST X-RADIATION, GAMMA RADIATION, CORPUSCULAR RADIATION OR PARTICLE BOMBARDMENT; TREATING RADIOACTIVELY CONTAMINATED MATERIAL; DECONTAMINATION ARRANGEMENTS THEREFOR). As a Foreign Corporation, Joint Stock Company “rosenergoatom” is one of the more focused assignees in the PatentsView dataset. By volume, Joint sits between JLN Solar, Inc. (8 patents, rank #32,153) and JPL Investments, Llc (8 patents, rank #32,161) - the closest US assignees by grant volume. The composite Innovation Score of 45.2/100 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. Historical data spans 2020 through 2024, with 8 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. Joint Stock Company “rosenergoatom”'s 7.3 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 Joint Stock Company “rosenergoatom” against peers pursuing similar technology classes.
