Portfolio overview

Hangzhou Silicon-magic Semiconductor Technology Co., Ltd. has been granted 14 US utility patents between 2022 and 2025, placing Hangzhou Silicon-magic Semiconductor Technology Co., Ltd. at #19,850 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, Hangzhou Silicon-magic Semiconductor Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Huaneng Clean Energy Research Institute (14 patents, rank #19,854) and Havis, Inc. (14 patents, rank #19,862) - the closest US assignees by grant volume. The composite Innovation Score of 44.4/100 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 2022 through 2025, with 14 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. Hangzhou Silicon-magic Semiconductor Technology Co., Ltd.'s 13.3 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.
