Portfolio overview

Stemrim Inc. has been granted 11 US utility patents between 2018 and 2025, placing Stemrim Inc. at rank #25,189 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Stemrim Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Stemrim sits between SSW Advanced Technologies, Llc (11 patents, rank #25,185) and Stratus Technologies Ireland Ltd. (11 patents, rank #25,193) - the closest US assignees by grant volume. The composite Innovation Score of 29.3/100 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. Between 2020 and 2025 the company received 9 grants, compared with 2 in the 2015–2019 window, a +350% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Stemrim Inc.'s 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stemrim Inc. against peers pursuing similar technology classes.
