This portfolio spans 0 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.0 claims per patent. As a Foreign Corporation, Black Donuts Engineering OY is one of the more focused assignees in the PatentsView dataset. By volume, Black sits between Benelli ARMI S.p.a. (26 patents, rank #11,567) and Bullfrog International, LC (26 patents, rank #11,575) - the closest US assignees by grant volume.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 1 grants, compared with 25 in the 2015–2019 window, a -96% 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. Black Donuts Engineering OY'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.

How to use this portfolio

Black's 26 grants land it in the top 98% 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 - Black ranks #11,576 of 50,000. Top 50 holders
  • 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.
