Portfolio overview

Silk Road Medical, Inc. has been granted 80 US utility patents between 2015 and 2025, placing Silk Road Medical, Inc. at rank #4,436 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 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, Silk Road Medical, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Silk sits between SK Biopharmaceuticals Co., Ltd. (80 patents, rank #4,432) and Tenacious Holdings, Inc. (80 patents, rank #4,440) - the closest US assignees by grant volume. The composite Innovation Score of 36.1/100 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 41 grants, compared with 39 in the 2015–2019 window, a +5% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Silk Road Medical, Inc.'s 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silk Road Medical, Inc. against peers pursuing similar technology classes.
