This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.2 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, SINTAI OPTICAL (SHENZHEN) CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.0/100 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 115 grants, compared with 92 in the 2015–2019 window — a +25% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. SINTAI OPTICAL (SHENZHEN) CO., LTD.'s 16.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SINTAI OPTICAL (SHENZHEN) CO., LTD. against peers pursuing similar technology classes.
