Portfolio overview

IQE Plc has been granted 27 US utility patents between 2017 and 2025, placing IQE Plc at #11,297 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.1 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, IQE Plc is one of the more focused assignees in the PatentsView dataset. By volume, IQE sits between Inserm (27 patents, rank #11,286) and Innovative Building Technologies, Llc (27 patents, rank #11,294) - the closest US assignees by grant volume. The composite Innovation Score of 38.6/100 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 17 grants, compared with 8 in the 2015–2019 window, a +113% 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. IQE Plc's 22.1 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 11 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.
