Portfolio overview
Kobayashi Pharmaceutical Co., Ltd. has been granted 90 US utility patents between 2015 and 2025, placing Kobayashi Pharmaceutical Co., Ltd. at rank #4,009 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 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, Kobayashi Pharmaceutical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.3/100 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 68 grants, compared with 22 in the 2015–2019 window — a +209% 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. Kobayashi Pharmaceutical Co., Ltd.'s 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kobayashi Pharmaceutical Co., Ltd. against peers pursuing similar technology classes.
