Portfolio overview

Caroma Industries Limited has been granted 26 US utility patents between 2015 and 2024, placing Caroma Industries Limited at #11,591 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.2 claims per patent with primary concentration in G05D (SYSTEMS FOR CONTROLLING OR REGULATING NON-ELECTRIC VARIABLES). As a Foreign Corporation, Caroma Industries Limited is one of the more focused assignees in the PatentsView dataset. By volume, Caroma sits between CNEX LABS, Inc. (26 patents, rank #11,592) and Centre For Addiction And Mental Health (26 patents, rank #11,600) - the closest US assignees by grant volume. The composite Innovation Score of 35.0/100 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. Between 2020 and 2024 the company received 12 grants, compared with 14 in the 2015–2019 window, a -14% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. 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. Caroma Industries Limited's 8.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 13 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

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.
