Portfolio overview

Protean Electric Limited has been granted 44 US utility patents between 2015 and 2025, placing Protean Electric Limited at #7,462 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.1 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Protean Electric Limited is one of the more focused assignees in the PatentsView dataset. By volume, Protean sits between Omniscient Neurotechnology Pty Limited (44 patents, rank #7,453) and Portable Multimedia Ltd. (44 patents, rank #7,461) - the closest US assignees by grant volume. The composite Innovation Score of 42.1/100 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 18 grants, compared with 25 in the 2015–2019 window, a -28% 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. Protean Electric Limited's 13.1 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 24 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
