Portfolio overview
Drive CJSC has been granted 9 US utility patents between 2018 and 2024, placing Drive CJSC at rank #28,605 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.3 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, Drive CJSC is one of the more focused assignees in the PatentsView dataset. By volume, Drive sits between Doubleday Acquisitions, Llc (9 patents, rank #28,601) and Duraplas, Lp (9 patents, rank #28,609) - the closest US assignees by grant volume. The composite Innovation Score of 21.3/100 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 4 grants, compared with 5 in the 2015–2019 window, a -20% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Drive CJSC's 2.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Drive CJSC against peers pursuing similar technology classes.

- Read that count against the largest US assignees before treating it as dominance - Drive ranks #28,605 of 50,000. Top 50 holders
- Most of this portfolio concentrates in H02M - see who else leads that technology area. H02M leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
