The verdict
Shandong holds 9 US patents across 11 technology areas, rank #30,006 of 50,000 tracked assignees.
Shandong Sinocera Functional Material Co., Ltd. has been granted 9 US utility patents between 2020 and 2025, placing Shandong Sinocera Functional Material Co., Ltd. at rank #30,006 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a Foreign Corporation, Shandong Sinocera Functional Material Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shandong sits between Serene Medical, Inc. (9 patents, rank #30,002) and Shanghai Jadic Optoelectronics Technology Co., Ltd (9 patents, rank #30,010) - the closest US assignees by grant volume. The composite Innovation Score of 40.8/100 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. Historical data spans 2020 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Shandong Sinocera Functional Material Co., Ltd.'s 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shandong Sinocera Functional Material Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shandong's 9 grants land it in the top 35% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
