The verdict
Dcstar holds 86 US patents across 4 technology areas, rank #4,150 of 50,000 tracked assignees.
Dcstar Inc has been granted 86 US utility patents between 2020 and 2025, placing Dcstar Inc at rank #4,150 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.2 claims per patent with primary concentration in A61M (DEVICES FOR INTRODUCING MEDIA INTO, OR ONTO, THE BODY ; DEVICES FOR TRANSDUCING BODY MEDIA OR FOR TAKING MEDIA FROM THE BODY ; DEVICES FOR PRODUCING OR ENDING SLEEP OR STUPOR). As a US Corporation, Dcstar Inc is one of the more focused assignees in the PatentsView dataset. By volume, Dcstar sits between Broadband Itv, Inc. (86 patents, rank #4,146) and Evernote Corporation (86 patents, rank #4,154) - the closest US assignees by grant volume. The composite Innovation Score of 45.6/100 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. Historical data spans 2020 through 2025, with 86 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Dcstar Inc's 5.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dcstar Inc against peers pursuing similar technology classes.

How to use this portfolio
Dcstar's 86 grants land it in the top 23% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
