Portfolio overview

ACE Light & Electronic TECH (ningbo) Co., Ltd. has been granted 26 US utility patents between 2018 and 2021, placing ACE Light & Electronic TECH (ningbo) Co., Ltd. at #11,524 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.9 claims per patent with primary concentration in F21Y (INDEXING SCHEME ASSOCIATED WITH SUBCLASSES F21K, F21L, F21S and F21V, RELATING TO THE FORM OR THE KIND OF THE LIGHT SOURCES OR OF THE COLOUR OF THE LIGHT EMITTED). As a Foreign Corporation, ACE Light & Electronic TECH (ningbo) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, ACE sits between Eyesight Mobile Technologies Ltd. (27 patents, rank #11,520) and Allergan Sales, Llc (26 patents, rank #11,528) - the closest US assignees by grant volume. The composite Innovation Score of 21.0/100 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 6 grants, compared with 20 in the 2015–2019 window, a -70% 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. ACE Light & Electronic TECH (ningbo) Co., Ltd.'s 2.9 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

ACE's 26 grants land it in the top 92% 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 - ACE ranks #11,524 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F21Y - see who else leads that technology area. F21Y 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.
