Portfolio overview

SCT Ltd. has been granted 21 US utility patents between 2020 and 2025, placing SCT Ltd. at #14,251 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in G09G (ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION). As a Foreign Corporation, SCT Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SCT sits between Sayfa R&D PTY Ltd (21 patents, rank #14,241) and Shanghai Easy-use Tools Enterprise Co., Ltd (21 patents, rank #14,249) - the closest US assignees by grant volume. The composite Innovation Score of 41.0/100 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 2020 through 2025, with 21 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. SCT Ltd.'s 15.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 14 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
