USPTO PatentsView assignee record - 5 granted patents across 1 technology areas, active 2015–2019. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: 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).
The verdict
Biostable holds 5 US patents across 1 technology areas, rank #45,132 of 50,000 tracked assignees.
Biostable Science & Engineering, Inc. has been granted 5 US utility patents between 2015 and 2019, placing Biostable Science & Engineering, Inc. at rank #45,132 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.4 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 US Corporation, Biostable Science & Engineering, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Biostable sits between Bionovo, Inc. (5 patents, rank #45,128) and Biotek Instruments, Inc (5 patents, rank #45,136) - the closest US assignees by grant volume. The composite Innovation Score of 22.6/100 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 0 grants, compared with 5 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Biostable Science & Engineering, Inc.'s 21.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Biostable Science & Engineering, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Biostable's 5 grants land it in the top 90% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
