Portfolio overview

General Plastic Industrial Co., Ltd. has been granted 41 US utility patents between 2015 and 2025, placing General Plastic Industrial Co., Ltd. at #7,851 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in G03G (ELECTROGRAPHY; ELECTROPHOTOGRAPHY; MAGNETOGRAPHY). As a Foreign Corporation, General Plastic Industrial Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, General sits between Fotonation Cayman Limited (41 patents, rank #7,844) and Gemvax & KAEL Co., Ltd. (41 patents, rank #7,852) - the closest US assignees by grant volume. The composite Innovation Score of 30.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 11 grants, compared with 28 in the 2015–2019 window, a -61% 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. General Plastic Industrial Co., Ltd.'s 15.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 5 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio

General's 41 grants land it in the top 64% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - General ranks #7,851 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G03G - see who else leads that technology area. G03G leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
