Portfolio overview

Unilumin Group Co., Ltd has been granted 43 US utility patents between 2015 and 2025, placing Unilumin Group Co., Ltd at #7,639 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in G09F (DISPLAYING; ADVERTISING; SIGNS; LABELS OR NAME-PLATES; SEALS). As a Foreign Corporation, Unilumin Group Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Unilumin sits between Tsudakoma Kogyo Kabushiki Kaisha (43 patents, rank #7,635) and Vaccinex, Inc. (43 patents, rank #7,643) - the closest US assignees by grant volume. The composite Innovation Score of 47.7/100 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 25 grants, compared with 14 in the 2015–2019 window, a +79% 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. Unilumin Group Co., Ltd's 7.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 21 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

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.
