Portfolio overview
ZHONGSHAN SHI SONGLIN FURNITURE CO., LTD. has been granted 22 US utility patents between 2015 and 2021, placing ZHONGSHAN SHI SONGLIN FURNITURE CO., LTD. at rank #13,806 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.2 claims per patent with primary concentration in A47C (CHAIRS; SOFAS; BEDS). As a Foreign Corporation, ZHONGSHAN SHI SONGLIN FURNITURE CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 15.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 3 grants, compared with 19 in the 2015–2019 window, a -84% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. ZHONGSHAN SHI SONGLIN FURNITURE CO., LTD.'s 1.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZHONGSHAN SHI SONGLIN FURNITURE CO., LTD. against peers pursuing similar technology classes.
