Portfolio overview

Zhejiang Shenghui Lighting Co., Ltd. has been granted 53 US utility patents between 2015 and 2021, placing Zhejiang Shenghui Lighting Co., Ltd. at #6,408 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a Foreign Corporation, Zhejiang Shenghui Lighting Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhejiang sits between Velcro BVBA (53 patents, rank #6,402) and B.box For Kids Developments Pty Ltd (53 patents, rank #6,410) - 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 1 grants, compared with 52 in the 2015–2019 window, a -98% 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. Zhejiang Shenghui Lighting Co., Ltd.'s 12.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 34 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
