USPTO PatentsView assignee record - 8 granted patents across 13 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B29D (PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE).
The verdict
Mesnac holds 8 US patents across 13 technology areas, rank #32,428 of 50,000 tracked assignees.
Mesnac Co., Ltd. has been granted 8 US utility patents between 2017 and 2025, placing Mesnac Co., Ltd. at rank #32,428 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.0 claims per patent with primary concentration in B29D (PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE). As a Foreign Corporation, Mesnac Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mesnac sits between Medizinische Universität GRAZ (8 patents, rank #32,424) and Metimedi Pharmaceuticals Co., Ltd. (8 patents, rank #32,432) - the closest US assignees by grant volume. The composite Innovation Score of 45.7/100 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 6 grants, compared with 2 in the 2015–2019 window, a +200% 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. Mesnac Co., Ltd.'s 9.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mesnac Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Mesnac's 8 grants land it in the top 22% 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.
