Portfolio overview

Rock Solid Industries International (pty) Ltd has been granted 34 US utility patents between 2021 and 2025, placing Rock Solid Industries International (pty) Ltd at #9,358 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.5 claims per patent with primary concentration in B60J (WINDOWS, WINDSCREENS, NON-FIXED ROOFS, DOORS, OR SIMILAR DEVICES FOR VEHICLES; REMOVABLE EXTERNAL PROTECTIVE COVERINGS SPECIALLY ADAPTED FOR VEHICLES). As a Foreign Corporation, Rock Solid Industries International (pty) Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Rock sits between Rovl Guides, Inc. (34 patents, rank #9,356) and SDG, Llc (34 patents, rank #9,364) - the closest US assignees by grant volume. The composite Innovation Score of 42.0/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 34 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Rock Solid Industries International (pty) Ltd's 4.5 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 4 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

  • Most of this portfolio concentrates in B60J - see who else leads that technology area. B60J 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.
