This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 claims per patent with primary concentration in A41C (CORSETS; BRASSIERES). As a Foreign Corporation, Mast Industries (far East) Limited is one of the more focused assignees in the PatentsView dataset. By volume, Mast sits between Marmon Utility Llc (19 patents, rank #15,458) and Metabolic Technologies, Llc (19 patents, rank #15,466) - the closest US assignees by grant volume. The composite Innovation Score of 41.1/100 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 14 grants, compared with 5 in the 2015–2019 window, a +180% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Mast Industries (far East) Limited's 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mast Industries (far East) Limited against peers pursuing similar technology classes.
