Portfolio overview

Shenzhen Qianyan Technology Ltd has been granted 22 US utility patents between 2023 and 2025, placing Shenzhen Qianyan Technology Ltd at #13,682 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.9 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, Shenzhen Qianyan Technology Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Sharrow Engineering Llc (22 patents, rank #13,696) and Shoulder Innovations, Inc. (22 patents, rank #13,704) - the closest US assignees by grant volume. The composite Innovation Score of 43.8/100 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 2023 through 2025, with 22 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. Shenzhen Qianyan Technology Ltd's 3.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 9 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
