Portfolio overview

Hangzhou Bensheng Pharmaceutical Co., Ltd. has been granted 12 US utility patents between 2015 and 2018, placing Hangzhou Bensheng Pharmaceutical Co., Ltd. at rank #22,682 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, Hangzhou Bensheng Pharmaceutical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 26.0/100 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 12 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 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. Hangzhou Bensheng Pharmaceutical Co., Ltd.'s 15.3 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 Hangzhou Bensheng Pharmaceutical Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Hangzhou's 12 grants land it in the top 81% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Hangzhou ranks #22,682 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A61P - see who else leads that technology area. A61P leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
