Portfolio overview

Shenzhen Grandsun Electronic Co., Ltd. has been granted 65 US utility patents between 2016 and 2025, placing Shenzhen Grandsun Electronic Co., Ltd. at #5,321 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.0 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a Foreign Corporation, Shenzhen Grandsun Electronic Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Seikagaku Corporation (65 patents, rank #5,317) and Suphatchatwong Innovation Co., Ltd. (65 patents, rank #5,325) - the closest US assignees by grant volume. The composite Innovation Score of 35.2/100 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 52 grants, compared with 12 in the 2015–2019 window, a +333% 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. Shenzhen Grandsun Electronic Co., Ltd.'s 6.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 16 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
