Portfolio overview

Shoulder Friends Institute has been granted 6 US utility patents between 2022 and 2024, placing Shoulder Friends Institute at rank #42,881 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a Foreign Corporation, Shoulder Friends Institute is one of the more focused assignees in the PatentsView dataset. By volume, Shoulder sits between Shinwa Syoji Co., Ltd. (6 patents, rank #42,877) and Sichuan Golden Ridge Intelligence Science & Technology Co., Ltd. (6 patents, rank #42,885) - the closest US assignees by grant volume. The composite Innovation Score of 38.9/100 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 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Shoulder Friends Institute's 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shoulder Friends Institute against peers pursuing similar technology classes.
