Portfolio overview

Sierra Space Corporation has been granted 16 US utility patents between 2022 and 2024, placing Sierra Space Corporation at rank #18,139 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in F05D (INDEXING SCHEME FOR ASPECTS RELATING TO NON-POSITIVE-DISPLACEMENT MACHINES OR ENGINES, GAS-TURBINES OR JET-PROPULSION PLANTS). As a US Corporation, Sierra Space Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Sierra sits between Shibumi Shade, Inc. (16 patents, rank #18,135) and Smiths Medical International Limited (16 patents, rank #18,143) - the closest US assignees by grant volume. The composite Innovation Score of 55.3/100 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 2022 through 2024, with 16 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. Sierra Space Corporation's 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sierra Space Corporation against peers pursuing similar technology classes.

How to use this portfolio

Sierra's 16 grants land it in the top 7% 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 - Sierra ranks #18,139 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F05D - see who else leads that technology area. F05D 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.
