This portfolio spans 0 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.0 claims per patent. As a Foreign Corporation, Shuangma Plastic Manufacturing Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Shuangma sits between Shenzhen Seefaa Scitech Co., Ltd.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 2 grants, compared with 12 in the 2015–2019 window, a -83% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Shuangma Plastic Manufacturing Inc.'s 1.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 0 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
