Portfolio overview

Meishan BOYA Advanced Materials Co., Ltd. has been granted 31 US utility patents between 2020 and 2025, placing Meishan BOYA Advanced Materials Co., Ltd. at rank #10,095 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in C30B (SINGLE-CRYSTAL GROWTH ; UNIDIRECTIONAL SOLIDIFICATION OF EUTECTIC MATERIAL OR UNIDIRECTIONAL DEMIXING OF EUTECTOID MATERIAL; REFINING BY ZONE-MELTING OF MATERIAL ; PRODUCTION OF A HOMOGENEOUS POLYCRYS). As a Foreign Corporation, Meishan BOYA Advanced Materials Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Meishan sits between Mahle Engine Systems UK Ltd (31 patents, rank #10,091) and Mawetal Llc (31 patents, rank #10,099) - the closest US assignees by grant volume. The composite Innovation Score of 54.8/100 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 31 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. Meishan BOYA Advanced Materials Co., Ltd.'s 17.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Meishan BOYA Advanced Materials Co., Ltd. against peers pursuing similar technology classes.
