Portfolio overview
Donghia Inc. has been granted 11 US utility patents between 2015 and 2020, placing Donghia Inc. at rank #24,190 across all assignees tracked by PlainPatent. This portfolio spans 0 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.0 claims per patent. As a US Corporation, Donghia Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Donghia sits between Dfinity Stiftung (11 patents, rank #24,186) and Doyle Manufacturing, Inc. (11 patents, rank #24,194) - the closest US assignees by grant volume. The composite Innovation Score of 9.2/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 1 grants, compared with 10 in the 2015–2019 window, a -90% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Donghia Inc.'s 1.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 0 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Donghia Inc. against peers pursuing 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.
